American liquid propellant intermediate range ballistic missile, developed by Douglas in 1956-1958. 60 deployed to Britain in 1958-1962. The basis for a family of Thor and Delta space launch vehicles, remaining in production into the 2010's.

AKA: B-75; Mk. 2; PGM-17A; SM-75; W49. Payload: 1,000 kg (2,200 lb). Thrust: 666.00 kN (149,722 lbf). Gross mass: 50,000 kg (110,000 lb). Height: 19.82 m (65.02 ft). Diameter: 2.44 m (8.00 ft). Span: 2.74 m (8.98 ft).

In 1954 the USAF realized that the Soviet Union – and perhaps more worryingly, the US Army – was developing intermediate range ballistic missiles which would be deployed several years before the Air Force's Atlas ICBM. The result was Thor, a crash December 1955 program to produce an Air Force intermediate range ballistic missile with the same range as the Army's Jupiter. USAF Missile Czar General Bernard Schriever dictated that the missile would be air-transportable in a C-124 Globemaster, use the inertial guidance, re-entry vehicle, and nuclear warhead being developed for Atlas. A single Rocketdyne 150,000 lb (68-metric-ton) thrust lox/kerosene engine would power the missile. This was to have been used as the sustainer engine for Atlas when the requirement was to launch a 2700 kg thermonuclear warhead over an intercontinental range. When it became apparent that the warhead could be reduced to less than half that weight, Atlas was downsized, and the large sustainer motor was no longer required. But the design was a perfect fit for Thor (related designs from Rocketdyne with the same thrust were under development for the Navaho cruise missile and the Jupiter).

Douglas was selected as prime contractor in December 1955 for one of the most accelerated crash programs in history. 'Chief Designer' of the Thor was Jack Bromberg, hired by Donald Douglas in the 1930's. Although not educated formally as an engineer, he was smart and dynamic, and a major influence in Douglas' winning bid to the USAF. Bromberg managed to fly a first prototype only thirteen months after go-ahead. In September 1958 the first of sixty Thors were deployed to missile sites in Great Britain under Project Emily. Deployment to four bases was completed in 1960, but at the end of 1962 the Thors were withdrawn from Britain as part of the secret codicil of Kennedy's deal to end the Cuban Missile Crisis. A few continued in an offensive military role as a nuclear-tipped anti-satellite system, based on Johnson Atoll in the Pacific, until the 1970's. Surplus Thors were used for a variety of suborbital re-entry vehicle tests. However Thor remained in production as a space launch vehicle, with a variety of upper stages. Dubbed the Delta by NASA, with solid rocket boosters, upgrades to the main engine, stretches to the first stage, and improvements to the upper stage, it became a workhorse of the American space program. Still in production in the 2010's, Jack Bromberg's stop-gap design became America's most reliable, most economical, and longest-lived launch vehicle.

Douglas SM-75-PGM-17 Thor

The Thor was the first Intermediate Range Ballistic Missile (IRBM) deployed by the U.S. armed forces. Although its military career was relatively short, its descendants are still in use as space launch vehicles.

Development began in 1954 with USAF studies about a 2400 km (1500 miles) range ballistic missile to complement the long-range ICBM. Soviet ballistic missile progress resulted in a decision in 1955 to develop an IRBM, to be named Thor, as quickly as possible. Using existing components (the Rocketdyne S-3D liquid-fuel rocket motor from the Army's SM-78-PGM-19 Jupiter IRBM, and the inertial guidance unit and Mk.2 reentry vehicle from the SM-65D-CGM-16D Atlas), and requiring the missile to be air-transportable by C-124 Globemaster transport aircraft, the basic design and overall dimensions of the Thor were quickly determined. Go-ahead for development was given in September 1955, and in December 1955, Douglas was selected as prime contractor for the SM-75 Thor IRBM.

Because of the many existing components development was extremely quick, and production of test missiles began as soon as the drawings were completed in August 1956. Testing of the XSM-75 missile began in December 1956, but the first launch attmepts all failed - sometimes in spectacular explosions - and the first successful flight finally occurred in September 1957. Other than the later production missiles, the first XSM-75s had small stabilizing fins at the base of the rocket. After the Soviet Sputnik launch in October 1957, the IRBM program was again accelerated, and Thor was ordered into full production in November 1957. In the next month, the first flight with a fully operational guidance system succeeded. All operational SM-75 missiles were stationed in Great Britain beginning in September 1958. Deployment was completed in June 1960 with 60 missiles at four bases. By then, the Royal Air Force had taken over the operation of the Thor bases and missiles.

The SM-75 was a single-stage rocket, powered by a single Rocketdyne S-3D (designated LR79-NA by the USAF) engine fueled by kerosene and liquid oxygen. The complete main propulsion system was designated as MB-3. Two small Rocketdyne LR101 vernier engines were used for fine-tuning thrust and directional control. The Thor could carry a 1.45 MT W-49 thermonuclear warhead to a distance of 2400 km (1500 miles), and the all-inertial guidance unit achieved an accuracy of 300+ m (1000+ ft) CEP. To protect them from conventional attacks and the weather, the missiles were stored horizontally in soft shelters at the base. After the launch order, the missile would be raised into the vertical, for fueling and launch. This resulted in an overall reaction time of about 10 minutes. Unarmed training missiles were designated USM-75.

During 1962, the Thor was used in a series of exo-atmospheric nuclear tests (called "Starfish", "Bluegill", and "Kingfish"), including the explosion of a 1.4 MT device at an altitude of 450 km (280 miles). Also in 1962, the USAF already started to plan the retirement of the SM-75 IRBM. The intended replacements were the GAM-87-AGM-48 Skybolt ALBM (Air-Launched Ballistic Missile), which was later cancelled, and the Navy's UGM-27 Polaris SLBM (Submarine-Launched Ballistic Missile). The first Thor was removed from base in November 1962, and by September 1963, all Thors had been deactivated and moved back to the USA. Production of Thor IRBMs totaled about 225, with a peak deployment level of 60 missiles.

In June 1963, shortly before its retirement in the UK, all Thor missiles were redesignated in the PGM-17 series as follows:

Old Designation New Designation
XSM-75 XPGM-17A
SM-75 PGM-17A
USM-75 PTM-17A

The final chapter in the military career of the Thor was its use as an anti-satellite weapon. In February 1962 the USAF had started Program 437 to provide for a nuclear ASAT (anti-satellite) capability. Unarmed tests of Thors as ASAT missiles began in February 1964, and by September 1964 the ASAT Thor was declared operational. From that time until the retirement in December 1972, the ADC (Air Defense Command) always had two Thor ASAT launchers on 24h alert. The designation of the Thor in the ASAT role was apparently still PGM-17A, although a redesignation to PIM-17A would have been appropriate.

After retirement as an IRBM, disarmed PGM-17As, as well as new-built Thors, were used by the USAF as space launch vehicles under the basic designation of SLV-2. The Thor was developed by McDonnell-Douglas (now Boeing) into the very successful Delta family of space launchers, still in use today. In 1990 the official designation of SB-3A was assigned to the USAF's Delta II rockets.

Subtopics

Thor DM-18 American orbital launch vehicle. Single stage vehicle adapted from Thor IRBM with no upper stage.

Delta American orbital launch vehicle. The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced.

(2) Develop a recoverable animal carrying satellite using rhesus monkeys; four flights during fiscal 1959. (3) Lunar impact missions could be attempted with a high probability of success by adding a Vanguard third stage to the Thor and Vanguard second stage vehicle; four vehicles should be planned for this mission beginning during the last quarter of 1958, (4) Four vehicles should be assigned the mission of circumlunar flight. Total cost of these programs was estimated at $26.8 million during fiscal 1958, and $30.4 million in fiscal 1959 including ground equipment and Thor production would have to be increased by two units per, month if the entire astronautics program were adopted as proposed.

In addition, the Thor missile was to be used as a booster for (1) "Able" re-entry tests; (2) recoverable satellites; (3) and moon impact. The latter program was not yet finally approved but planning actions were authorized to "expedite this project immediately upon receipt of DOD approval" and $1 million had been set aside to cover initial project costs.

    These were tentatively allocated as follows: three were assigned to Phase I "Able" series flights, six were assigned to the program for recoverable satellites, and five were assigned to Phase II "Able" for continued development leading to a Thor ICBM capability. (For a time Thor plus a second stage and warhead was considered as a means of acquiring an early emergency ICBM inventory well ahead of Atlas and Titan.) However, only eight additional launchings could be scheduled through 1958--three for Phase I "Able", three for recoverable satellites to be launched one a month beginning in October, and two in support of Phase II "Able" precisely guided reentry vehicles. Thus this appeared to be the maximum effort possible in the category of space related experimental flights essential to a more advance program. If a greater effort was desirable it would be necessary to obtain additional launching facilities, a problem that might be quickly and easily solved by modifying Navaho launch stands to accept Thor vehicles.

    These recommendations "should be undertaken promptly by the Air Force. " Other than the first project, converting Thor into an intercontinental range weapon by adding a second stage, the recommendations concerned the following space proposals: (1) develop and orbit a satellite equipped with a small television transmitter to furnish weather information. A Thor plus a second stage could accomplish the first orbital launch by September 1958.: (2) Develop a recoverable satellite equipped to carry a variety of payloads which might be ejected from orbit by decelerating devices. This project would also use a Thor booster with an added Vanguard second stage which could be launched by July 1958. (3) A Thor-Hustler (later called Agena) second stage to launch a 300 pound scientific satellite by October 1958., (4) As previously recommended, the Air Force was prepared to launch a moon rocket by using a Thor plus two Vanguard upper stages. Said the secretary: "In addition to the scientific data that can be obtained from such a flight, the United States could make a major international psychological gain by beating the Russians to the moon. I urge that this Air Force approach be used. " (Memo, SAF J. H. Douglas to the SOD, 14 Feb 58, subj: Thor and WS 117L Program.)

    The general Air Research and Development Command headquarters outline of the immediate planning task centered about designing a manned vehicle within a weight limitation of 2, 700-3,000 pounds which would have to contain a man, a life support system with a capacity to remain aloft for 48 hours, telemetry-communications, and a recovery system. The Air Force Ballistic Missile Division approach was directed to a more distant goal, K "Man on the Moon and Return. " By the second day of the conference general agreement on program objectives had been reached. Technical recommendations included selection of an improved thrust Thor with a fluorine-hydrazine second stage, 2, 700-3, 000 pound spacecraft and a General Electric guidance system. As then planned the complete experimental and test program would require approximately 30 Thor boosters, 8 to 12 Vanguard second stages and about 20 fluorine-hydrazine second stages for testing and advanced phases of the program. By the third day an abbreviated dra.ft development plan had been completed. The conference was pervaded by a strong sense of urgency, motivated by the dramatic Air Force mission to get a man in space at the earliest possible time. Those attending the conference anticipated accelerated program approval and scheduled contractor selection to begin on or about 10 April 1958., (Memo, Col C. H.

  • The Air Force Ballistic Missile Division published the development plan for an Air Force Manned Military Space Systems Program. - . Spacecraft: Man-In-Space-Soonest, Lunex.

    The objective was to ". achieve an early capability to land a man on the moon and return him safely to earth. The program represented a reasonable level of accomplishment with a minimum of time and money and called for start of a high priority program (similar to that enjoyed by ballistic missiles) characterized by "concurrency" and single Air Force agency management. The complete program would be carried out in four phases: first, "Man-In-Space-Soonest," was to determine functional capabilities and limitations of man in space by means of earth orbital flights--beginning with an instrumented 2,900 pound re-entry body, then a primate passenger and, finally, a manned capsule. The second, designated "Man-In-Space-Sophisticated," would use a drag type 3, 200 pound re-entry vehicle, capable of a 14 day manned space flight. This device would be used for earth orbital flight only but it would perform experiments essential to the final phase of the lunar program. The third phase, "Lunar Reconnaissance," would explore the moon by television camera and by means of a soft landing of an instrumented package on the moonIs surface. The final phase of the projected program was "Manned Lunar Landing and Return, " which would first test equipment by circumlunar flights returning to earth with instrumented capsules containing animals. At this stage of project development payload capacity would be increased to 9,000 pounds. The spacecraft would then undertake a full scale flight to the moon and safe return to earth with an animal passenger. The climax of the entire project would then be a manned lunar landing, brief surface exploration, and return to earth. This would be followed by other circumlunar flights to fully explore the moon's surface and gather additional physical data. The program was scheduled for completion in December of 1965 at a total estimated cost of $1.5 billion. Program cost estimates were based on use of Air Force rocket hardware and available ground facilities thus eliminating much new development and construction funding. However, new launch vehicle combinations would have to be developed progressing in performance as follows: a Thor-Vanguard second stage, a Thor-fluorine second stage, a "super" Titan with a fluorine-hydrazine second and third stages. Methods of landing involved use of retrorockets to insure a soft landing on the moon and return to earth through re-entry to a predetermined landing area.

    The proposed system was built around an Atlas booster, no second stage, mounting a light double walled capsule which would rely on a steel mesh drag chute for deceleration and recovery. The proposal was analyzed by Air Force space specialists who concluded that the plan was feasible but offered little margin for error. Furthermore, weight estimates were optimistic, its orbital endurance and altitude were low and it possessed no growth potential although use of Atlas as a booster appeared to have merit. Air Force Ballistic Missile Division felt adoption of the proposal would only gain three or four months over the much more versatile Thor-fluorine combination vehicle which would also be free from the major limitations inherent in the AVCO-Convair proposal.

However, Air Force headquarters considered it a certainty that direction of an Atlas boosted manned space flight would be given to the Air Force at an early date, that funds for the project would probably total $66 million and that a series of Thor boosted, instrument and animal capsule flights would precede the Atlas full sized instrumented capsule, chimpanzee, and manned shots. The Air Force would probably re-program to obtain whatever additional funds were required to support the program. The ballistic missile division was advised that while waiting for an authoritative "go ahead" it should continue preparation of work statements for industry competition and contractor selection so they might be coordinated with the Advanced Research iProjects Agency and the National Advisory Committee for Aeronautics.

  • Air Force Ballistic Missile Division received its first specific request.from the civilian space agency to support a "preliminary research program leading to manned space flight." - . Spacecraft: Man-In-Space-Soonest, Mercury.

    The division was requested to procure one Atlas C ballistic missile booster with its associated control and guidance equipment." '... This request was a forerunner of a support effort for a program "requiring approximately thirteen (13) ballistic missile boosters of the Thor and Atlas class."' The space agency would procure the payload, scheduled for May 1959 delivery. The missile division was to furnish detailed plans, subject to the approval of the National Aeronautics and Space Administration, for the design, construction and launching of this vehicle. One million dollars was immediately transferred to the Air Force with more money to be supplied as it was requested. (Msg, no cite number, Hq NASA, to Cmds. AFBMD, 25 Nov 58.)

    An Air Force Thor/Agena A booster vehicle lifted Discoverer II into orbit from Vandenberg AFB. Discoverer II became the world's first satellite to be stabilized in orbit in all three axes, to be maneuvered on command from earth, to separate a reentry vehicle on command, and to send its reentry vehicle back to earth. The capsule ejector system malfunctioned, causing the capsule to impact near Spitsbergen on 14 April rather than near Hawaii as planned. KH-1 prototype; tested capsule recovery techniques; did not carry camera; capsule recovery failed. Because of a timing error, the US believed that the capsule landed somewhere on the island of Spitsbergen, north of Norway, instead of landing in the recovery zone near Hawaii. The capsule was never found; and CIA officials suspect it may have been snatched by the Soviets. The search for this capsule formed the basis of the book and film 'Ice Station Zebra'.

    In the winter of 1960/1961, a US Discovery spy satellite capsule was found by loggers near Kalinin, 200 km north of Moscow. The loggers cracked it open with an axe. Sergei Khrushchev believed this to be the Discoverer 2 capsule. What was left was examined by Soviet engineers but didn’t reveal much information - it was a polished aluminium sphere, 30 cm in diameter, gilded on the exterior. Some said it was found as early as the winter of 1959.

    The first Oscar Phase I amateur satellite was launched piggyback with Discover 36. A group of enthusiasts in California formed Project OSCAR and persuaded the United States Air Force to replace ballast on the Agena upper stage with the 4.5 kg OSCAR I package. The satellite was box shaped with a single monopole antenna and battery powered. The 140 mW transmitter onboard discharged its batteries after three weeks. 570 Amateurs in 28 countries reported receiving its simple 'HI-HI' morse code signals on the VHF 2 meter band (144.983 MHz) until January 1, 1962. The speed of the HI-HI message was controlled by a temperature sensor inside the spacecraft. OSCAR I re-entered the atmosphere January 31, 1962 after 312 revolutions. Additional Details: here....

  • Space Systems Division awarded a letter contract to the Douglas Aircraft Company for the design, development, fabrication, assembly, and pre-flight testing of one Douglas Space Vehicle 2C (DSV-2C) spa - .

    This was originally proposed by the company in June 1961. The DSV-2C, later SLV-2A in Air Force nomenclature, was the Thrust Augmented Thor (TAT) that was the first attempt to combine solid and liquid fuel engines in a single space booster. Intended to fill the gap between the basic Thor booster (LV-2) and the Atlas (SLV-3), the TAT was to use three TX-33-52 solid-pro-pellant Sergeant rocket motors installed around the engine section and attached to the three main thrust beams. Each of the solid-rocket motors would generate 54,500 pounds of thrust for 27 seconds after lift-off. This increased the total thrust of the vehicle to over 330,000 pounds, vastly improving its payload capabilities. The new TAT would have a 50 percent improvement in payload capacity since it could place 1,450 pounds into a 300-NM circular orbit when launched from Cape Canaveral - a 500-pound increase over the present Thor/Agena booster.

    OSCAR II was launched piggyback with a United States Air Force satellite. OSCAR II was very similar to OSCAR I. Differences included (1) changing the surface thermal coatings to achieve a cooler internal spacecraft environment, (2) modifying the sensing system so the satellite temperature could be measured accurately as the batteries decayed, and (3) lowering the transmitter power output to 100 mW to extend the life of the onboard battery. OSCAR II lasted 18 days ceasing operation on June 20, 1962 and re-entered June 21, 1962.

    Successful high-altitude test of a Thor IRBM with a live nuclear warhead. The payload included test instrumentation and a W-49 warhead/Mk-4 re-entry vehicle. The 1.45 megaton bomb exploded at an altitude of 400 km. The explosion was visible 2,600 km away, at Kwajalein Atoll; an artificial aurora lasted seven minutes. The unforeseen and most militarily significant effect was the electromagnetic pulse (EMP) generated by the test. This caused power mains surges in Oahu, knocking out street lights, blowing fuses and circuit breakers, and triggering burglar alarms (and this in the days before microelectronics). The explosion supercharged the Van Allen radiation belts, resulting in several satellites malfunctioning.

    First test of a side-looking radar from outer space. The mission lasted only four days, as planned, before the batteries ran out of power during orbits 72-73. The radar operated 14 times in orbit, between 22 and 26 December, imaging swaths of the northeastern and western United States. Data collected from the 14 radar passes were transmitted over a wideband (UHF) data link as they were obtained ("real time") to the Vandenberg or New Boston ground station in view. In addition, during the first seven radar passes data were recorded on film on board the satellite, and on 23 December, during the 33rd orbit, the reentry capsule was jettisoned and recovered. The vehicle and payload performance were within acceptable limits on all parameters. The radar maps covered about 80,000 square miles and the resolution was better than 15 feet in azimuth and 80 feet in ground range. The mission, not declassified until 2012, proved the feasibility of space-based surveillance, leading to the operational Lacrosse satellites of the 1980's.

Decay Date: 1981-09-17 . USAF Sat Cat: 1620 . COSPAR: 1965-081A. Apogee: 1,515 km (941 mi). Perigee: 419 km (260 mi). Inclination: 87.4000 deg. Period: 104.40 min.

    OGO 2 was a large observatory instrumented with 20 experiments designed to make simultaneous, correlative observations of aurora and airglow emissions, energetic particles, magnetic field variations, ionospheric properties, etc., especially over the polar areas. Soon after achieving orbit, difficulties in maintaining earth lock with horizon scanners caused exhaustion of attitude control gas by October 23, 1965, 10 days after launch. At this time, the spacecraft entered a spin mode (about 0.11 rpm) with a large coning angle about the previously vertical axis. Five experiments became useless when the satellite went into this spin mode. Six additional experiments were degraded by this loss of attitude control. By April 1966, both batteries had failed, so subsequent observations were limited to sunlit portions of the orbit. By December 1966, only eight experiments were operational, five of which were not degraded by the spin mode operation. By April 1967, the tape recorders had malfunctioned and only one third of the recorded data could be processed. Spacecraft power and periods of operational scheduling conflicts created six large data gaps so that data were observed on a total of about 306 days of the 2-yr, 18-day total span of observed satellite data to November 1, 1967. The spacecraft was shut down on November 1, 1967, with eight experiments still operational. It was reactivated for 2 weeks in February 1968 to operate the rubidium vapor magnetometer experiment.

USAF Sat Cat: 1726 . COSPAR: 1965-089A. Apogee: 2,269 km (1,409 mi). Perigee: 1,120 km (690 mi). Inclination: 59.4000 deg. Period: 120.30 min.

    The primary objective of GEOS-A was to provide global geodetic measurements for determining the positions of fiducial control points on the Earth to an accuracy of 10 meters in an Earth centre of mass co-ordinate system, and to determine the structure of the Earth's gravity field to 5 parts in 10 million. Instrumentation included (1) four optical beacons, (2) laser reflectors, (3) a radio range transponder, (4) Doppler beacons, and (5) a range and range rate transponder. These were designed to operate simultaneously to fulfil the objectives of locating observation points (geodetic control stations) in a three dimensional earth centre-of-mass co-ordinate system within 10 m of accuracy, of defining the structure of the earth's irregular gravitational field and refining the locations and magnitudes of the large gravity anomalies, and of comparing results of the various systems onboard the spacecraft to determine the most accurate and reliable system. In January 1967, a failure in the satellite's command system rendered several geodetic systems inoperable. Radio doppler measurements and the passive laser reflector experiment could continue indefinitely, however. Additional Details: here....

  • Space Systems Division announced the purchase of newly designed Long Tank Thor (SLV-2G) space boosters to replace the Thrust Augmented Thor (SLV-2A). - .

    The Long Tank Thrust Augmented Thor (LTTAT) would be 14 feet longer than the older SLV-2A and would have a 40 percent increase in the volume of the liquid propellant fuel tanks. The additional fuel would give the Long Tank Thor a longer burn time than the Thrust Augmented Thor, 216 seconds versus 146 seconds. As a result of this improvement and the replacement of the Castor I (TX-33-52) solid-rocket booster motors with Thiokol's Castor II (TX-354-5) motors of 70.540 pounds of thrust, the new SLV-2G, dubbed the Thorad, would provide a 20 percent increase in payload capacity over the SLV-2A.

    Earth magnetic tail measurements. Lunar Orbit (Selenocentric). The Westinghouse Aerospace Division, under contract to National Aeronautics and Space Administration's Goddard Space Flight Center, engaged in the system design, integration, assembly and launch support for Anchored Interplanetary Monitoring Platform Satellite, officially designated Explorer 35 by the National Aeronautics and Space Administration. It was launched on July 19, 1967, with the primary objectives of investigation of interplanetary plasma and the interplanetary magnetic field out to and at the lunar distance, in either a captured lunar orbit or a geocentric orbit of the earth. In the geocentric orbit, the apogee was near or beyond the lunar distance. In a lunar orbit, additional objectives included obtaining data on dust distribution, lunar gravitational field, ionosphere, magnetic field, and radiation environment around the moon. AIMP-E also studied spatial and temporal relationships of geophysical and interplanetary phenomena simultaneously being studied by several other National Aeronautics and Space Administration satellites. The investigation in the vicinity of the moon provided for measurements of the characteristics of the interplanetary dust distribution, solar and galactic cosmic rays, as well as a study of the magnetohydrodynamic wake of the earth in the interplanetary medium at the lunar distances.

    OGO 4 was a large observatory instrumented with experiments designed to study the interrelationships between the aurora and airglow emissions, energetic particle activity, geomagnetic field variation, ionospheric ionization and recombination, and atmospheric heating which take place during a period of increased solar activity. After the spacecraft achieved orbit and the experiments were deployed into an operating mode, an attitude control problem occurred. This condition was corrected by ground control procedures until complete failure of the tape recording systems in mid-January 1969. At that time, due to the difficulty of maintaining attitude control without the tape recorders, the attitude control system was commanded off, and the spacecraft was placed into a spin-stabilized mode about the axis which was previously maintained vertically. In this mode, seven of the remaining experiments were turned off since no meaningful data could be observed by them. On October 23, 1969, the satellite was turned off. It was reactivated again in January 1970 for 2 months to obtain VLF observations.

    Biological capsule recovered. The scientific payload, consisting of 13 select biology and radiation experiments, was exposed to microgravity during 45 hours of Earth-orbital flight. Experimental biology packages on the spacecraft contained a variety of specimens, including insects, frog eggs, microorganisms and plants. The planned three-day mission was recalled early because of the threat of a tropical storm in the recovery area, and because of a communication problem between the spacecraft and the tracking systems. The primary objective of the Biosatellite II mission was to determine if organisms were more, or less, sensitive to ionizing radiation in microgravity than on Earth. To study this question, an artificial source of radiation was supplied to a group of experiments mounted in the forward part of the spacecraft.

    The geodetic instrumentation systems included (1) four optical beacons, (2) two C-band radar transponders, (3) a passive radar reflector, (4) a sequential collation of range radio range transponder, (5) a Goddard range and range rate transponder, (6) laser reflectors, and (7) Doppler beacons. Non-geodetic systems included a laser detector and a Minitrack interferometer beacon. The objectives of the spacecraft were to optimise optical station visibility periods and to provide complementary data for inclination-dependent terms established by the Explorer 29 (GEOS 1) gravimetric studies. The spacecraft was placed into a retrograde orbit to accomplish these objectives. Operational problems occurred in the main power system, optical beacon flash system, and the spacecraft clock, and adjustments in scheduling resulted in nominal operations.

    OGO 6 was a large observatory instrumented with 26 experiments designed to study the various interrelationships between, and latitudinal distributions of, high-altitude atmospheric parameters during a period of increased solar activity. On June 22, 1969, the spacecraft potential dropped significantly during sunlight operation and remained so during subsequent sunlight operation. This unexplained shift affected seven experiments which made measurements dependent upon knowledge of the spacecraft plasma sheath. During October 1969, a string of solar cells failed, but the only effect of the decreased power was to cause two experiments to change their mode of operation. Also during October 1969, a combination of manual and automatic attitude control was initiated, which extended the control gas lifetime of the attitude control system. In August 1970, tape recorder (TR) no. 1 operation degraded, so all recorded data were subsequently taken with TR no. 2. By September 1970, power and equipment degradation left 14 experiments operating normally, 3 partially, and 9 off. From October 14, 1970, TR no. 2 was used only on Wednesdays (world days) to conserve power and extend TR operation. In June 1971, the number of 'on' experiments decreased from 13 to 7, and on June 28, 1971, the spacecraft was placed in a spin-stabilized mode about the yaw (Z) axis and turned off due to difficulties with spacecraft power. OGO 6 was turned on again from October 10, 1971, through March 1972, for operation of experiment 25 by The Radio Research Laboratory, Japan.

    Biological capsule reentered 7/7/69. The intent had been to fly a 6 kg male pig-tailed monkey (Macaca nemestrina) named Bonnie in Earth-orbit for 30 days. However, after only 8.8 days in orbit, the mission was terminated because of the subject's deteriorating health. High development costs were a strong incentive for maximising the scientific return from the mission. Because of this, the scientific goals had become exceedingly ambitious over time, and a great many measurements were conducted on the single research subject flown. Although the mission was highly successful from a technical standpoint, the science results were apparently compromised. Additional Details: here....

    Space Electric Rocket Test; the ion engines aboard were operated until 1981. The SERT 2 development program started in 1966 and included thruster ground tests of 6742 hours and 5169 hours duration. A prototype version of the SERT 2 spacecraft was ground-tested for a period of 2400 hours with an operating ion engine. In addition to diagnostic equipment and related ion engine hardware, the spacecraft had two identical 15 cm diameter, mercury ion engines. Flight objectives included in-space operation for a period of 6 months, measurement of thrust, and demonstration of electromagnetic compatibility. The thruster maximum power level was 0.85 kW, and this provided operation at a 28 mN thrust level at 4200 s specific impulse. Flight data were obtained from 1970 to 1981 with an ion engine operating intermittently in one of three different modes, namely, HV ion extraction, discharge chamber operation only, or just neutralizer operation. Major results were that two mercury engines thrusted for periods of 3781 hours and 2011 hours. Test duration was limited due to shorts in the ion optical system. Thrust measured in space and on the ground agreed within the measurement uncertainties. Up to 300 thruster restarts were demonstrated. One power-processing unit accumulated nearly 17,900 hours during the course of the mission. Additionally, the ion propulsion system was electromagnetically compatible with all other spacecraft systems.

    KH-4B. The launch vehicle had a very cold boattail due to a hose discovered to be leaking away warming air to the boattail. The boattail was colder than usual, below freezing. Based on earlier tests of the Thor for just that condition, as relayed by Ed Dierdorf, Thor chief engineer at the time, the temp low was of no concern.

    The only problem was that those tests were made with a Thor that carried a Rocketdyne engine lubricated with "lube oil". The Thor being launched used a fuel additive, "Orinite" (like STP "super snot"). The technician that pumped the Orinite into its cannister later stated, "It wasn't for lack of orinite. I put it in just like the procedure said, and I could feel when it was full (with the hand pump). To make sure, I gave it another slug."

    That "other slug" cracked the output valve that was only supposed to be cracked by turbopump output pressure. When it cracked the output valve a bit of the "honey" squirted down the tube toward engine bearing jets. This line had a low spot in it by design. The Orinite settled there. When it was chilled by the low temp air at lox loading, the Orinite formed a plug.

    Unaware of this chain of circumstances, Launch Director Philip Payne made the decision to launch. The rocket (carrying Agena D and payload) flew for 18 seconds, then wiped out its gears, causing the turbine to overspeed and shed its vanes. These punctured various parts in the boattail like machine gun bullets. With loss of power, the rocket fell not far from the launch pad into Bear Creek canyon.

    The final cause was therefore found to be loss of engine lubrication at startup.

    LAGEOS (Laser Geodetic Satellite) was a very dense (high mass-to-area ratio) laser retroreflector satellite which provided a permanent reference point in a very stable orbit for such precision earth-dynamics measurements as crustal motions, regional strains, fault motions, polar motion and earth-rotation variations, solid earth tides, and other kinematic and dynamic parameters associated with earthquake assessment and alleviation. The performance in orbit of LAGEOS was limited only by degradation of the retroreflectors, so many decades of useful life can be expected. The high mass-to-area ratio and the precise, stable (attitude-independent) geometry of the spacecraft, together with the orbit, made this satellite the most precise position reference available. Because it is visible in all parts of the world and has an extended operation life in orbit, LAGEOS can serve as a fundamental standard for decades. Additional Details: here....

    International Sun-Earth Explorer; later renamed the International Cometary Explorer. Measured interaction between solar wind and Earth; rendezvoused with comet Giacobini-Zinner September 11, 1985. After several passes through the Earth's magnetotail, with gravity assists from lunar flybys in March, April, September and October of 1983, a final close lunar flyby (119.4 km above the moon's surface) on December 22, 1983, ejected the spacecraft out of the Earth-Moon system and into a heliocentric orbit ahead of the Earth, on a trajectory intercepting that of Comet Giacobini-Zinner. A total of fifteen propulsive maneuvers (four of which were planned) and five lunar flybys were needed to carry out the transfer from the halo orbit to an escape trajectory from the earth-moon system into a heliocentric orbit. The primary scientific objective of ICE was to study the interaction between the solar wind and a cometary atmosphere. As planned, the spacecraft traversed the plasma tail of Comet Giacobini-Zinner on September 11, 1985, and made in situ measurements of particles, fields, and waves. It also transited between the Sun and Comet Halley in late March 1986, when other spacecraft (Giotto, Planet-A, MS-T5, VEGA) were also in the vicinity of Comet Halley on their comet rendezvous missions. ICE became the first spacecraft to directly investigate two comets. An update to the ICE mission was approved by NASA headquarters in 1991. It defined a Heliospheric mission for ICE consisting of investigations of coronal mass ejections in coordination with ground-based observations, continued cosmic ray studies, and special period observations such as when ICE and Ulysses are on the same solar radial line. As of January 1990, ICE was in a 355 day heliocentric orbit with an aphelion of 1.03 AU, a perihelion of 0.93 AU and an inclination of 0.1 degree. This will bring it back to the vicinity of the earth-moon system in August, 2014. Termination of operations of ISEE 3 was authorized May 5, 1997.

    International Sun-Earth Explorer 3 spacecraft, also known as the International Cometary Explorer after its trip to P/Giacobini-Zinner in 1985, returned to the vicinity of the Earth in August 2014 following 30 years in solar orbit. On April 18 ISEE 3 was in a 0.927 x 1.034 AU x 0.06 deg solar orbit at a distance of 28.9 million km from Earth. A group of enthusiasts attempted to revive the spacecraft. ISEE 3 was the first spacecraft at the Earth-Sun L1 Lagrange point. However, in a special 1986 ceremony NASA Administrator James Fletcher transferred ownership of the spacecraft from NASA to the Smithsonian Institution. Additional Details: here....

    Flight P78-2 was successfully launched by SAMSO's Space Test Program. The mission was designated SCATHA (Spacecraft Charging at High Altitudes) and gathered data on the build-up of electrical charges on satellites operating at geosynchronous altitude. It was sponsored jointly by NASA and the Air Force. Spacecraft charging experiments. The SCATHA spacecraft had two charged particle injection systems, one of which was the Satellite Positive-Ion-Beam System (SPIBS). This was a xenon ion source which included some of the technologies used in thrusters: however, the discharge chamber was not performance optimized as was done with ion engines. Maximum operating power was 0.045 kW, and the ion source could produce a thrust of about 0.14 mN at a specific impulse of 350 s. Ions could be ejected at 1 keV or 2 keV. Neutralization was accomplished by a tantalum filament. The specific impulse was low because there was no attempt to optimize the propellant efficiency. The SPIBS system was ground-tested for a period of 600 hours. The SCATHA spacecraft was placed in a near geosynchronous orbit. Ion beam operations were performed intermittently over a 247 day period. The SCATHA flight demonstrated that a charged spacecraft, and the dielectric surfaces on it, could be safely discharged by emitting a very low energy (<50 eV) neutral plasma -- in effect shorting the spacecraft to the ambient plasma before dangerous charging levels could be reached.

    Relay Mirror Experiment; also known as Losat-R. RME validated stabilization, tracking, and pointing technologies for Strategic Defense Initiative (SDI) missions through a credible demonstration of a space-based relay mirror system. The Wideband Angular Vibration Experiment (WAVE) measured low-level angular vibrations affecting performance of acquisition, tracking, and pointing systems. The experiment demonstrated that a laser beam can be accurately relayed from the earth to an orbiting satellite 450 kilometers away and then back to a 3-meter target on the ground. It achieved relay beam pointing accuracy which was 16 times better than the technical requirement. WAVE demonstrated the capability to discern platform disturbance amplitudes of a few nanoradians at discrete frequencies and is therefore a candidate to fulfill similar requirements for future ATP experiments.
