The Atlas rocket, originally developed as America's first ICBM, was the basis for most early American space exploration and was that country's most successful medium-lift commercial launch vehicle. It launched America's first astronaut into orbit; the first generations of spy satellites; the first lunar orbiters and landers; the first probes to Venus, Mars, Mercury, Jupiter, and Saturn; and was America's most successful commercial launcher of communications satellites. Its innovative stage-and-a-half and 'balloon tank' design provided the best dry-mass fraction of any launch vehicle ever built. It was retired in 2004 after 576 launches in a 47-year career.

Atlas began with a US Army Air Corps request for proposal in October 1945 for long-range missile designs. By 10 January 1946, Consolidated-Vultee's engineers, under the leadership of Belgian-born Karel Bossart, submitted their proposals for two 6,000-nautical mile missiles: one subsonic, winged, and jet powered; the other supersonic, ballistic, and rocket powered. New technologies proposed for the ballistic missile included extremely low structural weight through use of steel monocoque single-wall construction tanks, kept rigid by internal tank pressure; gimbaled rocket engines; a detachable warhead section; and nearly single-stage to orbit performance through the ‘stage-and-a-half' approach of jettisoning the booster engines during the ascent.

On 19 April Convair received a contract for $1,893,000 to fabricate and test ten MX-774 Hiroc missiles to verify Bossart's innovative ballistic missile concepts. Captive testing of the MX-774 research rockets began in San Diego in 1947. In June, Consolidated Vultee was notified that it had lost the cruise missile competition; Northrop and Martin received contracts for development of their subsonic jet-powered cruise missile designs. Defense cutbacks forced the Air Force to terminate the MX-774 contract in July 1947, only three months before the first scheduled flight. The remaining contract funds allowed three MX-774's to be test-launched at White Sands Proving Ground in July-December 1947. Further work at Convair was reduced to ‘Mafia' low-level design activity using company funds.

The outbreak of the Korean war and the beginning of the cold war loosened the federal purse strings. Convair received a new contract (MX-1593) in September 1951 to begin design of a ballistic missile incorporating the design features validated by the MX-774. In 1953 the now-Convair Division of General Dynamics presented a plan to the Air Force for an accelerated program.

A major propulsion problem in the early 1950's was that liquid rocket motor ignition reliability was less than 50 percent. This led to the stage-and-a-half concept, with all engines ignited prior to lift-off and the booster engines jettisoned during flight. This allowed confirmation that all engines were functioning correctly before releasing the missile for flight.

A full go-ahead for the Atlas design was ordered in January 1955 as Weapon System WS107A-l. At Convair the project was known the Model 7 (in Russia, Korolev was working on the competing R-7 ICBM - evidently both sides wanted to use the lucky number). In September 1955, faced with intelligence reports of Russian progress on their ICBM, the Atlas received the highest national development priority. The project became one of the largest and most complex production, testing, and construction programs ever undertaken. The first propulsion system and component tests were conducted in June 1956; the first captive and flight-test missiles were completed later the same year.

The first Atlas A flight took place on 11 June 1957. In a tremendous national effort, by 1959 a peak of 33,000 personnel were working on the project. Total cost of the Atlas ICBM program to the United States was $8 billion. About a quarter of this went to Convair to design and develop the missile and launch facilities. The balance was for the tremendous cost of the ICBM launch facilities. For all of this effort, the Atlas was quickly obsolete, and the facilities were closed by 1966 after five years of service. However surplus ICBM's were stored, refurbished, and used as space launch vehicles until the last was flown in 1995 - 33 years after it was manufactured.

The first operational missile, the Atlas D, was the basis for launching the Mercury manned spacecraft into orbit. By use of Agena and Centaur upper stages, the Atlas became the medium-lift workhorse of American manned, reconnaissance, planetary, and geosynchronous-orbit space programs. After the retirement of the Atlas-Agena in 1978, the Centaur stage became standard on Atlas launch vehicles.

Centaur began with a contract awarded to General Dynamics by the Advanced Research Project Agency in 1958. The first space vehicle to use liquid hydrogen, Centaur was a pioneering project that solved the many technical problems of using the super-cryogenic and highly volatile fuel. Pratt & Whitney Aircraft was awarded the contract to develop Centaur's RL-10 engines. The US Air Force had already built the first large-quantity liquid hydrogen production facility for the deep black Suntan reconnaissance program.

In 1962, with the hydrogen propulsion technology being vital to the success of the Apollo program, Centaur management was transferred to NASA's Lewis Research Center. Lewis had fired their first experimental Lox/LH2 engine of 5,000 pounds thrust in 1953. The Centaur project was given the highest DX priority, but suffered delays due to management problems at both NASA and Convair. The first successful flight of Centaur atop Atlas occurred in November 1963. However thereafter von Braun's Saturn S-IV stage, using six of the RL-10 motors, leapfrogged the Centaur program . By the time of the first operational Centaur mission in May 1966, the S-IV had already completed its test series of six orbital flights. Yet thirty years later, the Saturn was long gone, and the Centaur continued, having been launched or planned for launch from Atlas, Titan, Delta, and Shuttle vehicles. Production continued into the 21st century, and no replacement for the RL-10 engine, the ultimate engine using the ultimate propellants, was ever put into production.

Associated Launch Sites
  • White Sands White Sands Missile Range occupies an area 160 x 65 km in the Tularosa Basin of southern New Mexico, across the Sacramento Mountain range from Roswell. In the 1930's, Robert Goddard, after surveying weather conditions and population densities, had selected Roswell for his pioneering rocket tests. White Sands, a true desert area, was even more unpopulated than Roswell. German advances in rocketry during World War II impelled the US Army to begin programs to exploit this technology. The White Sands Proving Ground was established for testing German and American long-range rockets on 9 July 1945. Seven days later the first atomic bomb was exploded at Trinity Site, near the north boundary of the range. The first launch of a Tiny Tim rocket was on 26 September 1945. On 11 October a Tiny Tim boosted a WAC Corporal rocket from the tower. This was the first use of Launch Complex 33, later to be used for V-2, Nike, Viking, Corporal, Lance and Multiple Launch Rocket System testing. More...
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...

Atlas Chronology


1945 October 31 - . LV Family: Atlas; Mace; Matador; Navaho; Snark. Launch Vehicle: Rascal.
  • US Strategic Missile Programs Begin - . Nation: USA. Program: Navaho. Request For Proposals were issued to 17 contractors by the US Army Air Force for studies of a 10-year R&D program of four missile types. The missiles were to be air-, rail-, road-, or ship- transportable, and fit in three range categories: 280 to 800 km; 800 to 2400 km; and 2400 to 8000 km. Minimum speed was 970 kph, requiring turbojet, ramjet, or rocket propulsion.

1946 January 11 - . LV Family: Atlas. Launch Vehicle: Atlas.
  • Strategic Missile Proposals - . Nation: USA. Bids were received in response to the USAAF request for proposal of the previous October. Vultee submitted proposals for two types (glide and ballistic) of 8000-km range missiles. North American proposed a three-year development program for a supersonic 800-km range missile, culminating in a production run of 50 missiles.

March to April 1946 - . LV Family: Atlas; Mace; Matador; Navaho; Snark. Launch Vehicle: Rascal.
  • Army Air Force awards nine one-year missile study contracts. - . Nation: USA. Program: Navaho. The MX-770 contract for an 800-km range boost-glide missile derived from the German A9 concept went to North American; this would evolve into the Navaho triple-sonic intercontinental cruise missile. Martin received a contract for development of the MX-771, a subsonic ground-launched cruise missile with an 800-km range; it would evolve into the Matador and Mace missiles. Curtiss-Wright and Republic received contracts for the MX-772 and MX-773 surface-to-surface missiles; they never advanced beyond the initial study stage. Convair received the contract for long-range rocket-powered missiles; this evolved into the Atlas ICBM. Northrtop received the MX-775 contract for a 5000-km range cruise missile; this eventually flew as the Snark. Bell receives a contract to develop the MX-776, a 160-km range rocket-powered supersonic missile to be launched from B-29 bombers. This would evolve into the Rascal. McDonnell received a study contract for the MX-777 air-to-surface missile; this evolved into the anti-submarine 'hydrobomb' concept and was eventually transferred to the Navy. Goodyear received contracts for the MX-778 and MX-779 air-to-surface missiles; these never advanced beyond the preliminary study stage. Concurrently, the USAAF had the GARPA surface-to-air missile project underway, which would evolve into Bomarc; the USA Army the Corporal and Hermes (later Redstone) surface-to-surface missiles and the Nike and Hermes A1 surface-to-air missiles; and the Navy a range of missile technology development projects (Regulus, Bat, Kingfisher, Little Joe, Lark, Bumblebee, Gorgon, Dove).

  • NASA National Space Vehicle Program - . Nation: USA. Program: Apollo. After consultation and discussion with DOD, NASA formulated a national space vehicle program. The central idea of the program was that a single launch vehicle should be developed for use in each series of future space missions. The launch vehicle would thus achieve a high degree of reliability, while the guidance and payload could be varied according to purpose of the mission. Four general-purpose launch vehicles were described: Vega, Centaur, Saturn, and Nova. The Nova booster stage would be powered by a cluster of four F-1 engines, the second stage by a single F-1, and the third stage would be the size of an intercontinental ballistic missile but would use liquid hydrogen as a fuel. This launch vehicle would be the first in a series that could transport a man to the lunar surface and return him safely to earth in a direct ascent mission. Four additional stages would be required in such a mission.

Mercury-Atlas 1 (MA-1) was launched from the Atlantic Missile Range in a test of spacecraft structural integrity under maximum heating conditions. After 58.5 seconds of flight, MA-1 exploded and the spacecraft was destroyed upon impact off-shore. None of the primary capsule test objectives were met. The mission objectives were to check the integrity of the spacecraft structure and afterbody shingles for a reentry associated with a critical abort and to evaluate the open-loop performance of the Atlas abort-sensing instrumentation system. The spacecraft contained no escape system and no test subject. Standard posigrade rockets were used to separate the spacecraft from the Atlas, but the retrorockets were dummies. The flight was terminated because of a launch vehicle and adapter structural failure. The spacecraft was destroyed upon impact with the water because the recovery system was not designed to actuate under the imposed flight conditions. Later most of the spacecraft, the booster engines, and the liquid oxygen vent valve were recovered from the ocean floor. Since none of the primary flight objectives was achieved, Mercury-Atlas 2 (MA-2) was planned to fulfill the mission.

Burke of McDonnell summarized the company's studies of the redesigned Mercury spacecraft for Space Task Group's senior staff. McDonnell had considered three configurations: (1) the minimum-change capsule, modified only to improve accessibility and handling, with an adapter added to carry such items as extra batteries; (2) a reconfigured capsule with an ejection seat installed and most of the equipment exterior to the pressure vessel on highly accessible pallets; and (3) a two-man capsule, similar to the reconfigured capsule except for the modification required for two rather than one-man operation. The capsule would be brought down on two Mercury-type main parachutes, the ejection seat serving as a redundant system. In evaluating the trajectory of the two-man capsule, McDonnell used Atlas Centaur booster performance data.

Mercury-Atlas 4 (MA-4) was launched from Cape Canaveral with special vibration and noise instrumentation and a mechanical crewman simulator aboard in addition to the normal spacecraft equipment. This was the first Mercury spacecraft to attain an earth orbit. The orbital apogee was 123 nautical miles and the perigee was 86 nautical miles. After one orbit, the spacecraft's orbital timing device triggered the retrograde rockets, and the spacecraft splashed in the Atlantic Ocean 161 miles east of Bermuda. Recovery was made by the USS Decatur. During the flight, only three slight deviations were noted - a small leak in the oxygen system; loss of voice contact over Australia; and the failure of an inverter in the environmental control system. Overall, the flight was highly successful: the Atlas booster performed well and demonstrated that it was ready for the manned flight, the spacecraft systems operated well, and the Mercury global tracking network and telemetry operated in an excellent manner and was ready to support manned orbital flight.

  • STG discussed development of automatic checkout system for the entire NASA launch vehicle program - . Nation: USA. Program: Apollo. The MSFC-STG Advanced Program Coordination Board met at STG and discussed the question of the development of an automatic checkout system which would include the entire launch vehicle program from the Saturn C-1 through the Nova. It agreed that the Apollo contractor should be instructed to make the spacecraft electrical subsystems compatible with the Saturn complex.

    In further discussion, Paul J. DeFries of Marshall Space Flight Center MSFC presented a list of proposed guidelines for use in studying early manned lunar landing missions:

    • The crew should draw on its own resources only when absolutely necessary. Equipment and service personnel external to the spacecraft should be used as much as possible.
    • Early lunar expeditions would receive active external support only up to the time of the launch from earth orbit.
    • The crew would board the spacecraft only after it was checked out and ready for final countdown and launch.
    • The first Apollo crews should have an emergency shelter available on the moon which could afford several months of lift: support and protection.
    • The capability for clocking an orbital launch vehicle with a propulsion stage - the "connecting mode" - should be possible.
    • The capability of fueling an orbital launch vehicle should be made available - "fueling mode."
    • The capability of making repairs, replacements, or adjustments in orbit should be developed.
    • For repairs, replacements, and adjustments on the orbital launch vehicle in earth orbit, two support vehicles would be necessary. These would be a Saturn C-1 launch vehicle manned by Apollo technicians and an unmanned Atlas-Centaur launch vehicle carrying repair kits.
    • Development of docking, testing of components, and techniques for docking and training of man in orbital operations could be carried out by a space ferry loaded with a Mercury capsule.
    Some of the points discussed in connection with these suggestions were:

    • Orbital launch operations were just as complex, if not more complex, than earth-launched operations.
    • A question existed as to how complex the orbital launch facility could be and what its function should be.
    • There was a possibility that the crew could do most of the checkout and launch operations. Studies should be made to define the role of the crew versus the role of a proposed MSFC auxiliary checkout and maintenance crew.
    After the discussion on orbital launch operations, the Board agreed that contemporary technology was inadequate to support such operations. Both STG and MSFC would need to study and develop both refueling and connector techniques.

  • NASA announced plans to develop a two-man Mercury capsule. - . Nation: USA. Related Persons: Gilruth. Program: Gemini. Spacecraft: Gemini. In Houston, Director Robert R. Gilruth of Manned Spacecraft Center announced plans to develop a two-man Mercury capsule. Built by McDonnell, it would be similar in shape to the Mercury capsule but slightly larger and from two to three times heavier. Its booster would be a modified Titan II. A major program objective would be orbital rendezvous. The two-man spacecraft would be launched into orbit and would attempt to rendezvous with an Agena stage put into orbit by an Atlas. Total cost of 12 capsules plus boosters and other equipment was estimated at $500 million. The two-man flight program would begin in the 1963-1964 period with several unmanned ballistic flights to test overall booster-spacecraft compatibility and system engineering. Several manned orbital flights would follow. Besides rendezvous flybys of the target vehicle, actual docking missions would be attempted in final flights. The spacecraft would be capable of missions of a week or more to train pilots for future long-duration circumlunar and lunar landing flights. The Mercury astronauts would serve as pilots for the program, but additional crew members might be phased in during the latter portions of the program.

First generation photo surveillance; return of camera and film by capsule; SAMOS type satellite. Reached orbit but failed to deorbit and be recovered. In his memoirs Sergei Khrushchev recounts recovery of what he believed to be a recoverable Samos, except the date given is the winter before tests of this configuration actually started. He relates that a second American capsule was recovered in the spring of 1961. It was equipped with a 30 cm lens and 100’s of metres of 10 cm wide film. Also recovered were a pear-shaped module made of fibreglass, and an inertial orientation system powered by electric motors. It may have been a SAMOS prototype. The capsule was found by tractor drivers, who disassembled it and used the film to wrap around the frame of their outhouse to provide some privacy in the treeless area. Unfortunately this ruined the film, preventing the Russians from developing it and discovering the technical capabilities of the system.

  • Small working group to discuss the feasibility of making the Gemini telemetry system a full PCM system. - . Nation: USA. Following a Lockheed briefing on pulse-code-modulation (PCM) instrumentation systems, representatives of Goddard Space Flight Center and Manned Spacecraft Center (MSC) formed a small working group to discuss the feasibility of making the Gemini telemetry system a full PCM system. PCM was a digital telemetry system which could provide more channels of information, faster data rates, improved accuracy, and less weight of equipment per data channel. Goddard had already reviewed several PCM ground station proposals and had concluded that such a system could handle future NASA programs. All who attended the meeting agreed that a full PCM telemetry system, airborne and ground, could be implemented in time to support the Gemini program. Gemini Project Office approved the formation of an MSC-Gemini PCM Instrumentation Working Group to be responsible for the implementation and compatibility of the airborne and ground PCM system for Gemini. On June 27, Walter C. Williams, MSC Associated Director, notified Goddard of NASA's decision 'to utilize a PCM telemetry system for Gemini and Agena real time data.' Ten sites were selected for the installation of PCM equipment; each of these also received dual acquisition equipment, dual digital command system, and pulse coders for distinguishing between the manned Gemini spacecraft and the Agena target when both were in orbit.

COSPAR: 1962-A-Rho-1. Mariner 2 was the first spacecraft to successfully flyby another planet. It was a backup for the Mariner 1 mission which failed shortly after launch to Venus. After launch and termination of the Agena first burn, the Agena-Mariner was in a 118 km altitude Earth parking orbit. The Agena second burn injected the Mariner 2 spacecraft into a geocentric escape hyperbola at 26 minutes 3 seconds after lift-off. Solar panel extension was completed about 44 minutes after launch. On 29 August 1962 cruise science experiments were turned on. A midcourse maneuver was initiated at 22:49:00 GMT on 4 September and completed at 2:45:25 GMT 5 September. On 8 September at 17:50 GMT the spacecraft suddenly lost its attitude control, which was restored by the gyroscopes 3 minutes later. The cause was unknown but may have been a collision with a small object. On October 31 the output from one solar panel deteriorated abruptly, and the science cruise instruments were turned off. A week later the panel resumed normal function and instruments were turned back on. The panel permanently failed on 15 November, but Mariner 2 was close enough to the Sun that one panel could supply adequate power. On December 14 the radiometers were turned on. Mariner 2 approached Venus from 30 degrees above the dark side of the planet, and passed below the planet at its closest distance of 34,773 km at 19:59:28 GMT 14 December 1962. After encounter, cruise mode resumed. Spacecraft perihelion occurred on 27 December at a distance of 105,464,560 km. The last transmission from Mariner 2 was received on 3 January 1963 at 07:00 GMT. Mariner 2 remains in heliocentric orbit. Scientific discoveries made by Mariner 2 included a slow retrograde rotation rate for Venus, hot surface temperatures and high surface pressures, a predominantly carbon dioxide atmosphere, continuous cloud cover with a top altitude of about 60 km, and no detectable magnetic field. It was also shown that in interplanetary space the solar wind streams continuously and the cosmic dust density is much lower than the near-Earth region. Improved estimates of Venus' mass and the value of the astronomical unit were made.

  • Mercury MA-8 - . Call Sign: Sigma 7. Crew: Schirra. Backup Crew: Cooper. Payload: Mercury SC16. Mass: 1,374 kg (3,029 lb). Nation: USA. Related Persons: Schirra; Cooper. Agency: NASA. Program: Mercury. Class: Manned. Type: Manned spacecraft. Flight: Mercury MA-8. Spacecraft: Mercury. Duration: 0.38 days. Decay Date: 1962-10-03 . USAF Sat Cat: 433 . COSPAR: 1962-B-Delta-1. Apogee: 285 km (177 mi). Perigee: 153 km (95 mi). Inclination: 32.5000 deg. Period: 88.80 min. The Sigma 7 spacecraft with Astronaut Walter M. Schirra, Jr., as pilot was launched into orbit by a Mercury-Atlas vehicle from Atlantic Missile Range. In the most successful American manned space flight to date, Schirra traveled nearly six orbits, returning to earth at a predetermined point in the Pacific Ocean 9 hours, 13 minutes after liftoff. Within 40 minutes after landing, he and his spacecraft were safely aboard the aircraft carrier U.S.S. Kearsarge. Schirra attempted and achieved a nearly perfect mission by sticking rigorously to mission plan.

The Ranger V lunar probe was launched from Atlantic Missile Range by an Atlas-Agena B launch vehicle. The Agena B stage attained parking orbit and 25 minutes later reignited to send Ranger V toward the moon. A malfunction in the Agena B guidance system resulted in excessive spacecraft velocity. The spacecraft's solar cells did not provide power and reversed command signals caused the telemetry antenna to lose earth acquisition. This made reception of the flight-path correction signal impossible and rendering its television cameras useless. Reversed command signals caused the telemetry antenna to lose earth acquisition, and mid-course correction was not possible. The spacecraft missed the Moon by 725 km and went into solar orbit. Gamma-ray data were collected for 4 hours prior to the loss of power. Ranger V was to have relayed television pictures of the lunar surface and rough-landed an instrumented capsule containing a seismometer. The spacecraft was tracked for 8 hours, 44 minutes, before its small reserve battery went dead. Additional Details: here....

  • NASA Headquarters' recent decision to cut the MSC budget for fiscal year 1963 from $687 million to $660 million. - . Nation: USA. Related Persons: Chamberlin. Spacecraft: Gemini; Gemini Paraglide. Wesley L. Hjornevik, Manned Spacecraft Center (MSC) Assistant Director for Administration, described to members of MSC's senior staff the implications of NASA Headquarters' recent decision to cut the MSC budget for fiscal year 1963 from $687 million to $660 million, the entire reduction to be borne by the Gemini program. Hjornevik feared that the Gemini budget, already tight, could absorb so large a cut only by dropping the paraglider, Agena, and all rendezvous equipment from the program. Gemini Project Office (GPO) reported that funding limitations had already forced Martin and McDonnell to reduce their level of activity. The first Gemini flight (unmanned) was rescheduled for December 1963, with the second (manned) to follow three months later, and subsequent flights at two-month intervals, with the first Agena (fifth mission) in August or September 1964. This four-month delay imposed by budget limitations required a large-scale reprogramming of Gemini development work, reflected chiefly in drastic reduction in the scale of planned test programs. Details of the necessary reprogramming had been worked out by December 20, when GPO Manager James A. Chamberlin reported that December 1963 was a realistic date for the first Gemini flight. Gemini funding for fiscal year 1963 totaled $232.8 million.

  • Manned Spacecraft Center informed Lockheed that Gemini program budget readjustments required reprogramming the Gemini-Agena program. - . Nation: USA. Subsequent meetings on November 2 and November 20 worked out the changes necessary to implement the Agena program at minimum cost. The overall test program for the Agena and its propulsion systems was significantly reduced, but in general neither the scope nor the requirements of the Agena program were altered. The major result of the reprogramming was a four-month slip in the scheduled launch date of the first Agena (to September 1964); this delay was about a month and a half less than had been anticipated when reprogramming began. In addition, Lockheed was to continue its program at a reduced level through the rest of 1962, a period of about six weeks, and to resume its normal level of activity on January 1, 1963.

The Model 8247 engine for the Gemini Agena's primary propulsion system was developed from the Model 8096 currently being flown in satellite and probe programs for NASA and the Air Force. Unlike the operational engine, the new engine was capable of being restarted several times in orbit, a Gemini program requirement. The principle change in the new engine was the substitution of liquid propellants for solid pyrotechnic 'starter cans' to start the gas generator. The unit tested was the development engine that had been assembled in March. In mid-April, the test engine was shipped to Arnold Engineering Development Center (AEDC), Tullahoma, Tennessee, for further development tests. At AEDC, test cell arrangements were completed April 12, with testing scheduled to begin in May.

  • NASA Headquarters approved rescheduling of the Gemini flight program as proposed by Gemini Project Office (GPO). - . Nation: USA. Spacecraft: Gemini; Gemini Parachute; Gemini Paraglide. Late delivery of the spacecraft systems coupled with the unexpectedly small number of Mercury systems incorporated in the Gemini spacecraft had forced GPO to review the flight program critically. In the revised program, the first flight was still set for December 1963 and was still to be unmanned, but it was now to be orbital rather than suborbital to flight-qualify launch vehicle subsystems and demonstrate the compatibility of the launch vehicle and spacecraft; no separation or recovery was planned. The second mission, originally a manned orbital flight, now became an unmanned suborbital ballistic flight schedule for July 1964. Its primary objection was to test spacecraft reentry under maximum heating-rate reentry conditions; it would also qualify the launch vehicle and all spacecraft systems required for manned orbital flight. The third flight, formerly planned as a manned orbital rendezvous mission, became the first manned flight, a short-duration (probably three-orbit) systems evaluation flight scheduled for October 1964. Subsequent flights were to follow at three-month intervals, ending in January 1967. Rendezvous terminal maneuvers were planned for missions 3 (if flight duration permitted) and 4, a seven-day mission using a rendezvous pod. The sixth flight was to be a 14-day long-duration mission identical to 4 except that no rendezvous maneuver missions with the Atlas-launched Agena D target vehicle. Water landing by parachute was planned for the first six flights and land landing by paraglider from flight 7 on.

Modifications of launch complexes 19 and 14, of the tracking network, and of Atlantic Missile Range checkout facilities were all on schedule, although no margin remained for complex 19 work. The Atlas and Agena presented no problems, but the Gemini launch vehicle schedule was tight; technical problems, notably stage I longitudinal oscillations and stage II engine instability, were compounded by funding difficulties. The Gemini spacecraft, suffering from late deliveries by subcontractors, was being reprogrammed.

  • Development tests of the Agena 8247 engine ended in an emergency shutdown. - . Nation: USA. Development tests of the Agena Model 8247 main engine at Arnold Engineering Development Center ended when the latch-type gas generator valve failed in testing, making an emergency shutdown of the engine necessary. The wrong choice of emergency shutdown procedures caused turbine overspeed and total failure of the engine's turbine pump assembly. As a result of this failure, the valve was redesigned. Because success of the new design was doubtful, a parallel program was initiated to design and develop an alternative valve configuration, solenoid-operated rather than latch-type. Intensive development testing followed; and in a meeting at Bell Aerosystems on November 15, the solenoid type was selected for use in the first flight system of the Agena target vehicle. The new valve allowed significant reductions in engine complexity and increased reliability, but the development effort imposed a serious delay in Preliminary Flight Rating Tests, which had been scheduled to begin in September 1963.

  • Lockheed's contract for the Gemini Agena target vehicle (GATV) was amended. - . Nation: USA. As a result of the seven-and-one-half-month relaxation of the required launch date for the first GATV, Lockheed was directed to use the improved version of the standard Agena, the AD-62 block of vehicles, instead of AD-13. The AD-62 block originally included the multistart engine, subsequently slipped to the AD-71 block. Lockheed accordingly was directed in January 1964 to substitute the AD-71 for AD-62. The combined effect of these changes was to use up much of the seven-and-one-half-month leeway. The change to AD-62 caused a two-month slip, and changing to AD-71 added a five-week slip. With much of the contingency time gone, the Agena schedule was now tight, and further slippage threatened to cause launch delays.

  • Bell Aerosystems began Preliminary Flight Rating Tests (PFRT) of the Agena primary propulsion system (PPS). - . Nation: USA. Tests were expected to be completed April 24 but were not actually concluded until late June. Testing proceeded with only minor problems through the first week of April. But in the following week PPS testing encountered what proved to be a six-week delay when the test unit's fuel and oxidizer start tanks failed. The two start tanks, stainless steel canisters with an internal bellows arrangement, supplied the propellants required to initiate the main engine start sequence. Visible longitudinal cracks in the outer shell allowed the gas which forced the propellants out of the tank to escape. Investigation revealed that the cracks had resulted from intergranular corrosion of the stainless steel tanks. The defective tanks were replaced by start tanks with a new heat-treated shell (delivered April 24), and PFRT resumed early in May.

  • Bell Aerosystems began Preliminary Flight Rating Tests (PFRT) of the Agena secondary propulsion system (SPS). - . Nation: USA. After proceeding through the acceleration and vibration test phases of PFRT without incident, the SPS began calibration firings early in April. The failure of a propellant valve in Unit I (the 16-pound thrust chamber fired prior to starting the main engine in order to orient propellant) of the SPS imposed a minor delay, but a more serious problem emerged late in April during high-temperature firings. The wall of the Unit II 200-pound thrust chamber burned through near the injector face after an accumulated PFRT firing time of 354 seconds, below the specification limit of 400 seconds although well in excess of the maximum orbital useful time of 200 seconds. The thrust chamber was replaced and testing continued, but PFRT, originally scheduled to end June 19, was first slipped to July 8, and finally completed in mid-August. To resolve the burn-through problem, Bell began a test program in September to determine the cause of failure.

  • Gemini mission plans for the first Agena rendezvous flight. - . Nation: USA. Related Persons: Aldrin. Spacecraft: Gemini; Gemini Radar. At a meeting of the Gemini Project Office's Trajectories and Orbits Panel, members of Flight Operations Division described two mission plans currently under consideration for the first Agena rendezvous flight. One was based on the concept of tangential Agena and spacecraft orbits, as proposed by Howard W. Tindall, Jr., and James T. Rose when they were members of Space Task Group. The second plan, based on a proposal by Edwin E. Aldrin, Jr., then of Air Force Space Systems Division, involved orbits which were concentric rather than tangential. The most significant advantage of the second plan was that it provided the greatest utilization of onboard backup techniques; that is, it was specifically designed to make optimum use of remaining onboard systems in the event of failure in the inertial guidance system platform, computer, or radar.

  • The propulsion test vehicle assembly (PTVA) arrived at Santa Cruz Test Base. - . Nation: USA. It consisted of a basic Agena structure with propellant pressurization, feed-and-load system, the primary propulsion system (PPS), and two secondary propulsion system (SPS) modules attached to the aft rack. The test program called for loading operations and hot firings of both propulsion systems to establish the adequacy of PPS and SPS propellant loading systems and associated ground equipment, to demonstrate proper overall system operation, and to provide engineering data on systems operation and the resulting environment. Start of testing was delayed by the PPS start tank problems which showed up during Preliminary Flight Rating Tests at Bell Aerosystems during April. Lockheed returned the PTVA main engine start tanks to Bell, where they were inspected and found to be defective. New tanks were ready by mid-May, but additional minor problems delayed the initiation of hot-firing until June 16.

  • FIRE 1 - . Nation: USA. Agency: NASA. Apogee: 837 km (520 mi). FIRE was a subscale model of the Apollo capsule used to verify the spacecraft's hypersonic flight and thermal characteristics. An Atlas D launch vehicle lifted a Project Fire spacecraft from Cape Kennedy in the first test of the heat that would be encountered by a spacecraft reentering the atmosphere at lunar-return velocity. During the spacecraft's fall toward earth, a solid-fuel Antares II rocket behind the payload fired for 30 seconds, increasing the descent speed to 40,501 kilometers (25,166 miles) per hour. Instruments in the spacecraft radioed temperature data to the ground. The spacecraft exterior reached an estimated temperature of 11,400 K (20,000 degrees F). About 32 minutes after launch, the spacecraft impacted into the Atlantic Ocean. The mission, sponsored by Langley Research Center, provided reentry heating measurements needed to evaluate heatshield materials and information on the communications blackout during reentry.

  • Lockheed began test-firing the propulsion test vehicle assembly at its Santa Cruz Test Base, after a delay caused primarily by problems with the Agena main engine start tanks. - . Nation: USA. The program, undertaken because of extensive changes in the propulsion system required to adapt the standard Agena D for use in Gemini missions, comprised three series of static-firing tests. The first series, in addition to providing base line performance for both primary and secondary propulsion systems (PPS and SPS), also subjected one SPS module to the dynamic and acoustic environment created by 55 seconds of PPS firing. The second series, successfully completed July 16, simulated a possible Gemini mission profile, including multiple firings and various coast and burn times on both PPS and SPS units. The third series, which concluded the test program on August 7, involved a maximum number of starts and minimum-impulse firings on both PPS and SPS. All firings were successful, and review of test data revealed only minor anomalies. The entire test program comprised 27 PPS firings for a run time totaling 545 seconds, 30 SPS Unit I firings totaling 286 seconds, and 11 SPS Unit II firings totaling 268 seconds. Post-test disassembly revealed no physical damage to any equipment.

COSPAR: 1964-054A. Apogee: 127,394 km (79,158 mi). Perigee: 21,446 km (13,325 mi). Inclination: 44.6000 deg. Period: 3,809.50 min. Two experiment booms failed to properly deploy, with one of the booms obscuring a horizon scanner's view of earth. As a result, the spacecraft attitude could not be earth oriented and OGO 1 remained spin stabilized at 5 rpm. Nevertheless, data from all 20 experiments on board was received, although at a 'less than expected capacity' from some of them. Twelve of the experiemnts were particle studies and two were magnetic field studies. In addition, there was one experiment for each of the following types of studies: interplanetary dust, VLF, Lyman-alpha, Gegenschein, atmospheric mass, and radio astronomy. During September 1964, acceptable data were received over 70% of the orbital path. By June 1969, data acquisition was limited to 10% of the orbital path. Spacecraft operation was restricted to Spring and Fall due to power supply limitations. There were 11 such 3-month periods prior to the spacecraft being put into stand-by mode on 25 November 1969. By April 1970 the spacecraft perigee had increased to 46,000 km and the inclination had increased to 58.8 deg. All support was terminated November 1, 1971.

Flight: Gemini 6. One change concerned a previous assumption of a 20-day Agena lifetime; it was now established that the Agena would not be modified to provide this. As a result, greater emphasis had to be placed on ensuring spacecraft launch on the same day as the Agena, primarily by relieving the constraint of no Agena maneuvers. The restriction on using Agena maneuvers had been removed to increase the probability of achieving rendezvous within the few days that the Agena would remain an acceptable target.

  • Mariner 4 - . Payload: Mariner C-3. Mass: 260 kg (570 lb). Nation: USA. Agency: NASA; JPL. Program: Mariner. Class: Mars. Type: Mars probe. Spacecraft: Mariner 3-4. USAF Sat Cat: 938 . COSPAR: 1964-077A. Mariner 4 provided the first up close pictures of Mars. The protective shroud covering Mariner 4 was jettisoned and the Agena D/Mariner 4 combination separated from the Atlas D booster at 14:27:23 GMT on 28 November 1964. The Agena D first burn from 14:28:14 to 14:30:38 put the spacecraft into an Earth parking orbit and the second burn from 15:02:53 to 15:04:28 injected the craft into a Mars transfer orbit. Mariner 4 separated from the Agena D at 15:07:09 and began cruise mode operations. The solar panels deployed and the scan platform was unlatched at 15:15:00 and Sun acquisition occurred 16 minutes later. A midcourse maneuver made on 5 December 1964.

    After a 228 day cruise, the spacecraft flew by Mars on July 14 and 15, 1965. Planetary science mode was turned on at 15:41:49 GMT on 14 July. The camera sequence started at 00:18:36 GMT on July 15 and 21 pictures plus 21 lines of a 22nd picture were taken. The images covered a discontinuous swath of Mars starting near 40 N, 170 E, down to about 35 S, 200 E, and then across to the terminator at 50 S, 255 E, representing about 1% of the planet's surface. The closest approach was 9,846 km from the Martian surface at 01:00:57 GMT 15 July 1965. The images taken during the flyby were stored in the onboard tape recorder. At 02:19:11 GMT Mariner 4 passed behind Mars as seen from Earth and the radio signal ceased. The signal was reacquired at 03:13:04 GMT when the spacecraft reappeared. Cruise mode was then re-established. Transmission of the taped images to Earth began about 8.5 hours after signal reacquisition and continued until 3 August. All images were transmitted twice to insure no data was missing or corrupt.

    The spacecraft performed all programmed activities successfully and returned useful data from launch until 22:05:07 GMT on 1 October 1965, when the distance from Earth (309.2 million km) and the antenna orientation temporarily halted signal acquisition. In 1967 Mariner 4 returned to the vicinity of Earth again and engineers decided to use the ageing craft for a series of operational and telemetry tests to improve their knowledge of the technologies that would be needed for future interplanetary spacecraft. The cosmic dust detector registered 17 hits in a 15 minute span on 15 September, part of an apparent micrometeoroid shower which temporarily changed the spacecraft attitude and probably slightly damaged the thermal shield. On 7 December the gas supply in the attitude control system was exhausted, and on December 10 and 11 a total of 83 micrometeoroid hits were recorded which caused perturbation of the attitude and degradation of the signal strength. On 21 December 1967 communications with Mariner 4 were terminated.

    Results

    The total data returned by the mission was 5.2 million bits. All experiments operated successfully with the exception of the ionization chamber/Geiger counter which failed in February, 1965 and the plasma probe, which had its performance degraded by a resistor failure on 6 December 1964. The images returned showed a Moon-like cratered terrain (which later missions showed was not typical for Mars, but only for the more ancient region imaged by Mariner 4). A surface atmospheric pressure of 4.1 to 7.0 mb was estimated and no magnetic field was detected.

  • Lockheed initiated a "Ten-point Plan for C&C Equipment." - . Nation: USA. The Agena command and communication (C and C) system comprised the electronic systems for tracking the vehicle, for monitoring the performance of its various subsystems, and for verifying operating commands for orbital operations. Because of the unique requirements of the Gemini mission, in particular rendezvous and docking, Lockheed had had to design and develop a new C and C system for the Gemini target vehicle. Numerous failures and problems calling for rework during the initial manufacturing stages of the C and C system suggested the existence of mechanical and electronic design deficiencies. Aerospace, which had assumed technical surveillance functions for the Gemini Agena in the fall of 1964, was instrumental in bringing these problems to the attention of Air Force and Lockheed top management. Among the results of the 10-point plan were several redesigned programmer circuits and packaging changes, closer monitoring of vendor work, expedited failure analysis, and improved quality control.

USAF Sat Cat: 1086 . COSPAR: 1965-010A. Returned 7137 photos before lunar impact. The Atlas- Agena B booster injected the Agena and Ranger 8 into an Earth parking orbit at 185 km altitude 7 minutes after launch. Fourteen minutes later a 90 second burn of the Agena put the spacecraft into lunar transfer trajectory, and several minutes later the Ranger and Agena separated. The Ranger solar panels were deployed, attitude control activated, and spacecraft transmissions switched from the omni-directional antenna to the high-gain antenna by 21:30 GMT. On 18 February at a distance of 160,000 km from Earth the planned mid-course manoeuvre took place, involving reorientation and a 59 second rocket burn. During the 27 minute manoeuvre, spacecraft transmitter power dropped severely, so that lock was lost on all telemetry channels. This continued intermittently until the rocket burn, at which time power returned to normal. The telemetry dropout had no serious effects on the mission. A planned terminal sequence to point the cameras more in the direction of flight just before reaching the Moon was cancelled to allow the cameras to cover a greater area of the Moon's surface.

    Ranger 8 reached the Moon on 20 February 1965. The first image was taken at 9:34:32 GMT at an altitude of 2510 km. Transmission of 7,137 photographs of good quality occurred over the final 23 minutes of flight. The final image taken before impact has a resolution of 1.5 meters. The spacecraft encountered the lunar surface in a direct hyperbolic trajectory, with incoming asymptotic direction at an angle of -13.6 degrees from the lunar equator. The orbit plane was inclined 16.5 degrees to the lunar equator. After 64.9 hours of flight, impact occurred at 09:57:36.756 GMT on 20 February 1965 in Mare Tranquillitatis at approximately 2.67 degrees N, 24.65 degrees E. Impact velocity was slightly less than 2.68 km/s.

USAF Sat Cat: 1294 . COSPAR: 1965-023A. Ranger 9, last of the series, returned 5814 images before lunar impact. The target was Alphonsus, a large crater about 12 degrees south of the lunar equator. The probe was timed to arrive when lighting conditions would be at their best. The Atlas- Agena B booster injected the Agena and Ranger 9 into an Earth parking orbit at 185 km altitude. A 90 second Agena 2nd burn put the spacecraft into lunar transfer trajectory. This was followed by the separation of the Agena and Ranger. The initial trajectory was highly accurate; uncorrected, the craft would have landed only 650 km north of Alphonsus. 70 minutes after launch the command was given to deploy solar panels, activate attitude control, and switch from the omni-directional antenna to the high-gain antenna. The accuracy of the initial trajectory enabled delay of the planned mid-course correction from 22 March to 23 March when the manoeuvre was initiated at 12:03 GMT. After orientation, a 31 second rocket burn at 12:30 GMT, and reorientation, the manoeuvre was completed at 13:30 GMT. Ranger 9 reached the Moon on 24 March 1965. At 13:31 GMT a terminal manoeuvre was executed to orient the spacecraft so the cameras were more in line with the flight direction to improve the resolution of the pictures. Twenty minutes before impact the one-minute camera system warm-up began. The first image was taken at 13:49:41 at an altitude of 2363 km. Transmission of 5,814 good contrast photographs was made during the final 19 minutes of flight. The final image taken before impact has a resolution of 0.3 meters. The spacecraft encountered the lunar surface with an incoming asymptotic direction at an angle of -5.6 degrees from the lunar equator. The orbit plane was inclined 15.6 degrees to the lunar equator. After 64.5 hours of flight, impact occurred at 14:08:19.994 GMT at approximately 12.83 S latitude, 357.63 E longitude in the crater Alphonsus. Impact velocity was 2.67 km/s. Millions of Americans followed the spacecraft's descent via real time television coverage provided to the three networks of many of the F-channel images (primarily camera B but also some camera A pictures) were provided for this flight.

    The pictures showed the rim and floor of the crater in fine detail: in those just prior to impact, objects less than a foot in size were discernible.

    A panel of scientists presented some preliminary conclusions from Ranger IX at a press conference that same afternoon. Crater rims and ridges inside the walls, they believed, were harder and smoother than the moon's dusty plains, and therefore were considered likely sites for future manned landings. Generally, the panel was dubious about landing on crater floors however. Apparently, the floors were solidified volcanic material incapable of supporting a spacecraft. Investigators believed several types of craters were seen that were of nonmeteoric origin. These findings reinforced arguments that the moon at one time had experienced volcanic activity. Later the images were shown to the press as a continuous-motion movie, leading astronaut Wally Schirra to yell ‘bail out you fool!’ just before the final frame.

An Atlas D booster propelled the instrumented probe, called a "flying thermometer," into a ballistic trajectory over 805 km (500 mi) high. After 26 minutes of flight, when the spacecraft began its descent, a solid-fueled Antares rocket accelerated its fall.

    The probe entered the atmosphere at a speed of 40,877 km (25,400 mph) and generated temperatures of about 11,206K (20,000 degrees F). Data on heating were transmitted to ground stations throughout the descent. Thirty-two minutes after the launch - and but six minutes after the Antares was fired - the device impacted in the Atlantic about 8,256 km (5,130 mi) southeast of the Cape.

USAF Sat Cat: 2394 . COSPAR: 1966-073A. Lunar Orbiter I was launched from Cape Kennedy Launch Complex 13 at 3:26 p.m. EDT August 10 to photograph possible Apollo landing sites from lunar orbit. The Atlas-Agena D launch vehicle injected the spacecraft into its planned 90-hour trajectory to the moon. A midcourse correction maneuver was made at 8 p.m. the next day; a planned second midcourse maneuver was not necessary. A faultless deboost maneuver on August 14 achieved the desired initial elliptic orbit around the moon, and one week later the spacecraft was commanded to make a transfer maneuver to place it in a final close-in elliptic orbit of the moon.

    During the spacecraft's stay in the final close-in orbit, the gravitational fields of the earth and the moon were expected to influence the orbital elements. The influence was verified by spacecraft tracking data, which showed that the perilune altitude varied with time. From an initial perilune altitude of 58 kilometers, the perilune decreased to 49 kilometers. At this time an orbit adjustment maneuver began an increase in the altitude, which was expected to reach a maximum after three months and then begin to decrease again. The spacecraft was expected to impact on the lunar surface about six months after the orbit adjustment.

    During the photo-acquisition phase of the flight, August 18 to 29, Lunar Orbiter I photographed the 9 selected primary potential Apollo landing sites, including the one in which Surveyor I landed; 7 other potential Apollo landing sites; the east limb of the moon; and 11 areas on the far side of the moon. Lunar Orbiter I also took photos of the earth, giving man the first view of the earth from the vicinity of the moon (this particular view has been widely publicized). A total of 207 frames (sets of medium- and high-resolution pictures) were taken, 38 while the spacecraft was in initial orbit, the remainder while it was in the final close-in orbit. Lunar Orbiter I achieved its mission objectives, and, with the exception of the high-resolution camera, the performance of the photo subsystem and other spacecraft subsystems was outstanding. At the completion of the photo readouts, the spacecraft had responded to about 5,000 discrete commands from the earth and had made about 700 maneuvers.

    Photographs obtained during the mission were assessed and screened by representatives of the Lunar Orbiter Project Office, U.S. Geological Survey, DOD mapping agencies, MSC, and Jet Propulsion Laboratory. The spacecraft was deliberately crashed into moon after the mission was completed.

COSPAR: 1966-084A. Soft lunar landing attempt failed. Surveyor II was launched from Cape Kennedy at 8:32 a.m. EDT. The Atlas-Centaur launch vehicle placed the spacecraft on a nearly perfect lunar intercept trajectory that would have missed the aim point by about 130 kilometers. Following injection, the spacecraft successfully accomplished all required sequences up to the midcourse thrust phase. This phase was not successful because of the failure of one of the three vernier engines to ignite, causing eventual loss of the mission. Contact with the spacecraft was lost at 5:35 a.m. EDT, September 22, and impact on the lunar surface was predicted at 11:18 p.m. on that day.

USAF Sat Cat: 2534 . COSPAR: 1966-100A. Lunar Orbiter II was launched at 6:21 p.m. EST from Launch Complex 13 at Cape Kennedy, to photograph possible landing sites on the moon for the Apollo program. The Atlas-Agena D booster placed the spacecraft in an earth-parking orbit and, after a 14-minute coast, injected it into its 94-hour trajectory toward the moon. A midcourse correction maneuver on November 8 increased the velocity from 3,051 to 3,133 kilometers per hour. At that time the spacecraft was 265,485 kilometers from the earth.

    The spacecraft executed a deboost maneuver at 3:26 p.m., November 10, while 352,370 kilometers from the earth and 1,260 kilometers from the moon and traveling at a speed of 5,028 kilometers per hour. The maneuver permitted the lunar gravitational field to pull the spacecraft into the planned initial orbit around the moon. On November 15, a micrometeoroid hit was detected by one of the 20 thin-walled pressurized sensors.

    The spacecraft was transferred into its final close-in orbit around the moon at 5:58 p.m. November 15 and the photo-acquisition phase of Lunar Orbiter II's mission began November 18. Thirteen selected primary potential landing sites and a number of secondary sites were to be photographed. By the morning of November 25, the spacecraft had taken 208 of the 211 photographs planned and pictures of all 13 selected potential landing sites. It also made 205 attitude change maneuvers and responded to 2,421 commands.

    The status report of the Lunar Orbiter II mission as of November 28 indicated that the first phase of the photographic mission was completed when the final photo was taken on the afternoon of November 25. On November 26, the developing web was cut with a hot wire in response to a command from the earth. Failure to achieve the cut would have prevented the final readout of all 211 photos. Readout began immediately after the cut was made. One day early, December 6, the readout terminated when a transmitter failed, and three medium-resolution and two high-resolution photos of primary site 1 were lost. Full low-resolution coverage of the site had been provided, however, and other data continued to be transmitted. Three meteoroid hits had been detected.

The thrusters had the capability to operate at 5 setpoints from 18 to 89 microN. Thrusters were configured so they could be used for East-West station-keeping. Prior to launch, a 5 cm cesium thruster was life tested for 2245 hours at the 67 microN thrust level. However the Centaur upper stage did not achieve a second burn and the spacecraft remained attached to the Centaur in a 218 km by 760 km orbit. It was estimated that the pressure at these altitudes was between 10^-6 and 10^-8 Torr. Each of the two engines was tested on at least two occasions each over the throttling range. Combined test time of the two engines was about 10 hours over a 55 day period. The spacecraft re-entered the atmosphere on October 17, 1968. TheATS-4 flight was the first successful orbital test of an ion engine. There was no evidence of IPS electromagnetic interference related to spacecraft subsystems. Measured values of neutralizer emission current were much less than the ion beam current, implying inadequate neutralization. The spacecraft potential was about -132V which was much different than the anticipated value of about -40V.

  • Mariner 6 - . Payload: Mariner 69-3. Mass: 412 kg (908 lb). Nation: USA. Agency: NASA; JPL. Program: Mariner. Class: Mars. Type: Mars probe. Spacecraft: Mariner 6-7. USAF Sat Cat: 3759 . COSPAR: 1969-014A. Mars flyby 31 July 1969; returned 75 images of Martian surface. Ten days before the scheduled launch, a faulty switch opened the main valves on the Atlas stage. This released the pressure which supported the Atlas structure, and as the booster deflated it began to crumple. Two ground crewman started pressurizing pumps, saving the structure from further collapse. The two ground crewman, who had acted at risk of the 12-story rocket collapsing on them, were awarded Exceptional Bravery Medals from NASA.

    The Mariner 6 spacecraft was removed, put on another Atlas/Centaur, and launched on schedule. The main booster was jettisoned 4 min. 38 sec. after launch, followed by a 7.5 minute Centaur burn to inject the spacecraft into Mars direct trajectory. After Mariner 6 separated from the Centaur the solar panels were deployed. A midcourse correction involving a 5.35 second burn of the hydrazine rocket occurred on 1 March 1969. A few days later explosive valves were deployed to unlatch the scan platform. Some bright particles released during the explosion distracted the Canopus sensor, and attitude lock was lost temporarily. It was decided to place the spacecraft on inertial guidance for the Mars flyby to prevent a similar occurrence.

    On 29 July, 50 hours before closest approach, the scan platform was pointed to Mars and the scientific instruments turned on. Imaging of Mars began 2 hours later. For the next 41 hours, 49 approach images (plus a 50th fractional image) of Mars were taken through the narrow-angle camera. At 05:03 UT on 31 July the near-encounter phase began, including collection of 26 close-up images. Due to a cooling system failure, channel 1 of the IR spectrometer did not cool sufficiently to allow measurements from 6 to 14 micrometers so no infrared data were obtained over this range. Closest approach occurred at 05:19:07 UT at a distance of 3431 km from the martian surface. Eleven minutes later Mariner 6 passed behind Mars and reappeared after 25 minutes. X-band occultation data were taken during the entrance and exit phases. Science and imaging data were played back and transmitted over the next few days. The spacecraft was then returned to cruise mode which included engineering and communications tests, star photography TV tests, and UV scans of the Milky Way and an area containing comet 1969-B. Periodic tracking of the spacecraft in its heliocentric orbit was also done.

    Science Results

    Mariner 6 returned 49 far encounter and 26 near encounter images of Mars. Close-ups from the near encounter phases covered 20% of the surface. The spacecraft instruments measured UV and IR emissions and radio refractivity of the Martian atmosphere. Images showed the surface of Mars to be very different from that of the Moon, in some contrast to the results from Mariner 4. The south polar cap was identified as being composed predominantly of carbon dioxide. Atmospheric surface pressure was estimated at between 6 and 7 mb. Radio science refined estimates of the mass, radius and shape of Mars.

COSPAR: 1969-030A. Mars flyby 5 August 1969; returned 126 images of Martian surface. Mariner 7 was launched on a direct-ascent trajectory to Mars 31 days after Mariner 6. On 8 April 1969 a midcourse correction was made by firing the hydrazine moter for 7.6 seconds. On 8 May Mariner 7 was put on gyro control to avoid attitude control problems which were affecting Mariner 6. On 31 July telemetry from Mariner 7 was suddenly lost and the spacecraft was commanded to switch to the low-gain antenna. It was later successfully switched back to the high-gain antenna. It was thought that leaking gases, perhaps from the battery which later failed a few days before encounter, had caused the anomaly.

    At 09:32:33 GMT on 2 August 1969 Mariner 7 bagan the far-encounter sequence involving imaging of Mars with the narrow angle camera. Over the next 57 hours, ending about 5 hours before closest approach, 93 images of Mars were taken and transmitted. The spacecraft was reprogrammed as a result of analysis of Mariner 6 images. The new sequence called for the spacecraft to go further south than originally planned, take more near-encounter pictures, and collect more scientific data on the lighted side of Mars. Data from the dark side of Mars were to be transmitted directly back to Earth but there would be no room on the digital recorder for backup due to the added dayside data. At closest approach, 05:00:49 GMT on 5 August, Mariner 7 was 3430 km above the martian surface. Over this period, 33 near-encounter images were taken. About 19 minutes after the flyby, the spacecraft went behind Mars and emerged roughly 30 minutes later. X-band occultation data were taken during the entrance and exit phases. Science and imaging data were played back and transmitted over the next few days. The spacecraft was then returned to cruise mode which included engineering and communications tests, star photography TV tests, and UV scans of the Milky Way and an area containing comet 1969-B. Periodic tracking of the spacecraft in its heliocentric orbit was also done.

    Science Results

    The total data return for Mariners 6 and 7 was 800 million bits. Mariner 7 returned 93 far and 33 near encounter images. Close-ups from the near encounter phases covered 20% of the surface. The spacecraft instruments measured UV and IR emissions and radio refractivity of the Martian atmosphere.

Applications Technology Satellite; communications tests. Launch vehicle successfully put the payload into a geosynchronous transfer orbit. The spacecraft maneuvered into geostationary orbit at 108 degrees W. The purpose of this flight was to demonstrate North-South Stationkeeping of a geosynchronous satellite. ATS-5 was equipped with an ion engine package identical to that on ATS-4. Once in geosynchronous orbit the spacecraft could not be despun as planned, and thus the spacecraft gravity gradient stabilization could not be implemented. The spacecraft spin rate was about 76 revolutions per minute, and this caused an effective 4g acceleration on the cesium feed system. The high g-loading on the cesium feed system caused flooding of the discharge chamber, and normal operation of the thruster with ion beam extraction could not be performed. The IPS was instead be operated as a neutral plasma source, without high-voltage ion extraction, along with the wire neutralizer to examine spacecraft charging effects. The neutralizer was also operated by itself to provide electron injection for the spacecraft charging experiments. Positioned in geosynchronous orbit over the Americas at 105 deg W in 1969-1977; over the Americas at 70 deg W in 1977-1983.

COSPAR: 1971-051A. The first spacecraft to orbit another planet. The Mariner Mars 71 mission was planned to consist of two spacecraft on complementary missions. Mariner 8 was to map 70 % of the Martian surface and Mariner 9 was to study temporal changes in the Martian atmosphere and on the Martian surface. The launch failure of Mariner 8 forced Mariner 9 to combine the mission objectives of both. For the survey portion of the mission, the planetary surface was to be mapped with the same resolution as planned for the original mission, although the resolution of pictures of the polar regions would be decreased due to the increased slant range. The variable features experiments were changed from studies of six given areas every 5 days to studies of smaller regions every 17 days. Mariner 9 was launched on a direct trajectory to Mars. Separation from the booster occurred at 22:36 GMT. The four solar panels were deployed at 22:40 GMT. The sensors locked onto the Sun at 23:16, shortly after the spacecraft left the Earth's shadow and Canopus acquisition was achieved at 02:26 GMT 31 May. A planned midcourse maneuver was executed on 5 June. Mariner 9 arrived at Mars on 14 November 1971 after a 167 day flight. A 15 minute 23 second rocket burn put the spacecraft into Mars orbit. The insertion orbit had a periapsis of 1398 km and a period of 12 hr, 34 min. Two days later a 6 second rocket burn changed the orbital period to just under 12 hours with a periapsis of 1387 km. A correction trim maneuver was made on 30 December on the 94th orbit which raised the periapsis to 1650 km and changed the orbital period to 11:59:28 so that synchronous data transmissions could be made to the Goldstone 64-m DSN antenna.

    Imaging of the surface of Mars by Mariner 9 was delayed by a dust storm which started on 22 September 1971 in the Noachis region. The storm quickly grew into one of the largest global storms ever observed on Mars. By the time the spacecraft arrived at Mars no surface details could be seen except the summits of Olympus Mons and the three Tharsis volcanoes. The storm abated through November and December and normal mapping operations began. The spacecraft gathered data on the atmospheric composition, density, pressure, and temperature and also the surface composition, temperature, gravity, and topography of Mars. A total of 54 billion bits of scientific data were returned, including 7329 images covering the entire planet. After depleting its supply of attitude control gas, the spacecraft was turned off on 27 October 1972. Mariner 9 was left in an orbit which should not decay for at least 50 years, after which the spacecraft will enter the Martian atmosphere.

    The Mariner 9 mission resulted in a global mapping of the surface of Mars, including the first detailed views of the martian volcanoes, Valles Marineris, the polar caps, and the satellites Phobos and Deimos. It also provided information on global dust storms, the gravity field as well as evidence for surface aeolian activity.

Pioneer 11 was the second mission to investigate Jupiter and the outer solar system and the first to explore the planet Saturn and its main rings. Pioneer 11, like Pioneer 10, used Jupiter's gravitational field to alter its trajectory radically. It passed close to Saturn and then it followed an escape trajectory from the solar system. During its closest approach, December 4, 1974, Pioneer 11 passed to within 34,000 km of Jupiter's cloud tops. It passed by Saturn on September 1, 1979, at a distance of 21,000 km from Saturn's cloud tops. The spacecraft has operated on a backup transmitter since launch. Instrument power sharing began in February 1985 due to declining RTG power output. Science operations and daily telemetry ceased on September 30, 1995 when the RTG power level was insufficient to operate any experiments.

COSPAR: 1973-085A. Mariner 10 was the first spacecraft to reach Mercury. Mariner 10 was placed in a parking orbit for 25 minutes after launch, then accelerated to a trans-Venus escape trajectory. The television and ultraviolet experiments were trained on the comet Kohoutek while the spacecraft was en route to its destination. The vehicle's first planetary encounter was with Venus on February 5, 1974, at a distance of 4200 km. Mariner 10 took 4,000 photos of Venus, which revealed a nearly round planet enveloped in smooth cloud layers. The gravity of Venus bent the orbit of the spacecraft and sent it towards Mercury. It crossed the orbit of Mercury on March 29, 1974, at 20:46 GMT, at a distance of 704 km from the surface. Photographs taken during the pass revealed an intensely cratered, Moon-like surface and a faint atmosphere of mostly helium. After the first flyby, Mariner 10 entered solar orbit, which permitted two more rendezvous with Mercury. On September 21, 1974, the second Mercury rendezvous, at an altitude of about 47,000 km, provided another opportunity to photograph the sunlit side of the planet and the south polar region. The third and final Mercury encounter on March 16, 1975, at an altitude of 327 km, yielded 300 photographs and magnetic field measurements. The vehicle was turned off March 24, 1975 when the supply of attitude-control gas was depleted.

  • Pioneer Venus Orbiter - . Payload: Pioneer-Venus 1. Mass: 582 kg (1,283 lb). Nation: USA. Agency: NASA Ames. Program: Pioneer. Class: Venus. Type: Venus probe. Spacecraft: Pioneer 12. Decay Date: 1992-10-22 . USAF Sat Cat: 10911 . COSPAR: 1978-051A. The Pioneer Venus Orbiter was inserted into an elliptical orbit around Venus on December 4, 1978. After entering orbit around Venus in 1978, the spacecraft returned global maps of the planet's clouds, atmosphere and ionosphere, measurements of the atmosphere-solar wind interaction, and radar maps of 93 percent of the planet's surface. Additionally, the vehicle made use of several opportunities to make systematic UV observations of several comets. From Venus orbit insertion to July 1980, periapsis was held between 142 and 253 km (at 17 degrees north latitude) to facilitate radar and ionospheric measurements. The spacecraft was in a 24 hour orbit with an apoapsis of 66,900 km. Thereafter, the periapsis was allowed to rise (to 2290 km at maximum) and then fall, to conserve fuel. In 1991 the Radar Mapper was reactivated to investigate previously inaccessible southern portions of the planet. In May 1992 Pioneer Venus began the final phase of its mission, in which the periapsis was held between 150 and 250 km until the fuel ran out and atmospheric entry destroyed the spacecraft. With a planned primary mission duration of only eight months, the spacecraft remained in operation until October 8, 1992 when it finally burned up in Venus' atmosphere after running out of propellant.

  • Pioneer Venus 2 - . Payload: Pioneer-Venus 2. Mass: 904 kg (1,992 lb). Nation: USA. Agency: NASA Ames. Program: Pioneer. Class: Venus. Type: Venus probe. Spacecraft: Pioneer 13. Decay Date: 1978-12-09 . USAF Sat Cat: 11001 . COSPAR: 1978-078A. The Pioneer Venus Multiprobe consisted of a bus which carried one large and three small `atmospheric probes. The large probe was released on November 16, 1978 and the three small probes on November 20. All four probes entered the Venus atmosphere on December 9, followed by the bus. The small probes were each targeted at different parts of the planet and were named accordingly. The North probe entered the atmosphere at about 60 degrees north latitude on the day side. The night probe entered on the night side. The day probe entered well into the day side, and was the only one of the four probes which continued to send radio signals back after impact, for over an hour. With no heat shield or parachute, the bus survived and made measurements only to about 110 km altitude before burning up. It afforded the only direct view of the upper Venus atmosphere, as the probes did not begin making direct measurements until they had decelerated lower in the atmosphere.

  • NOAA B - . Payload: NOAA B. Mass: 1,405 kg (3,097 lb). Nation: USA. Agency: NOAA. Program: Tiros. Class: Earth. Type: Weather satellite. Spacecraft: Tiros N. Decay Date: 1981-05-03 . USAF Sat Cat: 11819 . COSPAR: 1980-043A. Apogee: 1,445 km (897 mi). Perigee: 264 km (164 mi). Inclination: 92.2000 deg. Period: 102.10 min. Unusable orbit; would have been NOAA 7. At engine start up, one of the booster engines suffered an internal fuel leak, causing it to run at about 80% thrust. As a result the booster was low on velocity and heavy on propellant over much of its flight and ran an incredible 50 seconds longer than the nominal burn. The NOAA Advanced TIROS payload was designed with no direct communication with the booster, and unaware of the booster problem, at 375 sec after liftoff attempted to separate with the booster still firing. The booster's continued thrusting defeated the payload's attempt to perform the required pitch maneuver. When the payload fired its apogee kick motor, it blew the top of the booster's liquid oxygen tank off. The spacecraft survived all this, but the resultant orbit was highly elliptical rather than the desired circular sun-synchronous. The mission was a total loss.

USAF Sat Cat: 26871 . COSPAR: 2001-031A. Apogee: 35,813 km (22,253 mi). Perigee: 35,769 km (22,225 mi). Inclination: 0.0000 deg. Period: 1,436.30 min. Launch delayed from July 12, 15 and 22. The GOES-M weather satellite was placed by the Atlas AC-142 Centaur stage into a 164 x 505 km parking orbit and then a super synchronous transfer orbit of 274 x 42275 km x 20 deg. GOES-M was a Loral 1300-series satellite with a single solar array and a solar attitude control sail. Launch mass was 2279 kg and dry mass 1042 kg. The Geostationary Operational Environmental Satellites were developed by NASA-Goddard and were transferred to the NOAA weather agency when operational. In addition to the usual weather imager/sounder, GOES-M carried a new solar soft X-ray imager. Earlier GOES satellites carried simple X-ray collimator detectors, but the new SXI was a full-fledged grazing incidence telescope similar to the SXT on Japan's Yohkoh satellite. The GOES-M satellite was redesignated GOES 12 once in orbit.

    GOES 12 was a 980 kg, 973 W spacecraft that carried an IR imager, a "sounder", and an X-ray imager. The IR imager was a Cassegrain telescope covering five wavelength channels, 0.55-0.75, 3.80-4.00, 6.50-7.00, 10.20-11.20, and 11.50-12.50 microns. It provided images covering 3,000 km x 3,000 km every 41 seconds, by scanning the area in 16 square kilometer sections. The "sounder" provided vertical distribution of temperature, moisture and ozone, by passive monitoring in 18 depth-dependent wavelengths. (Long wave IR: 14.71, 14.37, 14.06, 13.64, 13.37, 12.66, and 12.02 microns. Medium wave IR: 11.03, 9.71, 7.43, 7.02, and 6.51 microns. Short wave IR: 4.57, 4.52, 4.45, 4.13, 3.98, and 3.74 microns. There was also another band at visible wavelength 0.7 microns, to provide pictures of cloud tops.) The sounder covered an area of 3,000 km x 3,000 km in about 42 minutes. Another instrument package named SEM (Space Environment Monitor) monitored the energetic electrons and protons in the magnetosphere and the X-rays from the Sun. The above three had been carried on the earlier GOES missions, but GOES 12 carried also an X-ray imager providing an X-ray (about 0.1-1.0 nm wavelength) picture of the solar disk. For some months, the spacecraft was to be on standby, to be activated and moved to a desired longitude. As of 5 September 2001 located at 89.93 deg W drifting at 0.001 deg W per day. As of 2007 Mar 11 located at 74.73W drifting at 0.014E degrees per day.

USAF Sat Cat: 26905 . COSPAR: 2001-040A. Launch delayed from July 31. First of a new series of naval electronic intelligence satellites for the National Reconnaissance Office (NRO). The Lockheed Martin Atlas IIAS AC-160 put the vehicle in a transfer orbit. The phrasing of the launch commentary implied that the second burn left the payload in 'transfer orbit', but several observers saw the bright Centaur in the typical final deployment orbit of the earlier NOSS satellites. Therefore it seemed the first burn was to a transfer orbit of around 180 x 1100 km x 63 deg. The second burn at 1629 GMT put the Centaur and payload into an 1100 x 1100 km x 63 deg orbit. The design was apparently quite different from earlier generation NOSS satellites since only one companion satellite was deployed rather than two. Prime contractor for the new satellites was again believed to be Lockheed Martin Astronautics at Denver. The NRL probably continued to have a management and technical role in the program under overall NRO auspices.

Launch delayed from October 31, November 13 and 26, 2001 and February 6 due to contract dispute with Boeing over performance of earlier satellites of the series. The Centaur upper stage entered a 167 x 578 km parking orbit and then placed the payload into a 247 x 29135 km x 27.1 deg subsynchronous transfer orbit. NASA's TDRS-I (TDRS-9) data relay satellite used a Boeing BSS-601 bus and was to provide S, Ku and Ka band communications for the Shuttle and International Space Station. After launch a problem developed with the fuel supply from one of the satellite's four propellant tanks. The tanks were paired, so losing one tank cuts the propellant supply in half. A test burn of the General Dynamics R-4D apogee motor raised the orbit to 433 x 29146 km x 26.4 deg on March 11 and a larger perigee burn raised the apogee to geostationary altitude, 429 x 35800 km, on March 13. A further burn on March 19, raised the orbit to 3521 x 35789 km and lowered the inclination to 21.4 deg. A burn on March 25 raised the orbit further to 8383 x 35811 km and lowered inclination to 17.4 deg. As of 2007 Mar 11 located at 62.04W drifting at 0.008W degrees per day.
