I was in the Blockhouse at Complex 11 while a static test was performed on an Atlas Able on Complex 12. It did explode. Did it ever! After a couple of hours the six of us were allowed out of the blockhouse and saw all the damage to our complex...I had a tiny piece of that missile for a long time that somehow wound up on my person...labeled 9C.

    The next Atlas Able would not fly until over a year later, using the Atlas D as the booster stage.

  • Ranger 1 - . Payload: NASA P-32 (RA-1). Mass: 306 kg (674 lb). Nation: USA. Agency: NASA. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 1-2. Decay Date: 1961-08-30 . USAF Sat Cat: 173 . COSPAR: 1961-Phi-1. Apogee: 446 km (277 mi). Perigee: 179 km (111 mi). Inclination: 32.9000 deg. Period: 90.60 min. Lunar probe; failed to leave Earth orbit. Ranger 1, a test version of the spacecraft which would attempt an unmanned crash landing on the moon, was launched from the Atlantic Missile Range by an Atlas-Agena B booster. The 306 kg spacecraft did not attain the scheduled extremely elongated orbit because of the misfiring of the Agena B rocket. Although the spacecraft systems were tested successfully, only part of the eight project experiments could be carried out. Ranger 1 reentered on August 29 after 111 orbits. Ranger 1's primary mission was to test the performance of those functions and parts that are necessary for carrying out subsequent lunar and planetary missions using essentially the same spacecraft design.

1961 November 18 - . 08:12 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 117D (AA2) / Agena B 6002 (AA2). FAILURE: Agena B Second Stage failed to restart.. Failed Stage: 2.
  • Ranger 2 - . Payload: NASA P-33 (RA-2). Mass: 304 kg (670 lb). Nation: USA. Agency: NASA. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 1-2. Decay Date: 1961-11-20 . USAF Sat Cat: 206 . COSPAR: 1961-A-Theta-1. Apogee: 242 km (150 mi). Perigee: 150 km (90 mi). Inclination: 33.3000 deg. Period: 88.30 min. This was a flight test of the Ranger spacecraft system designed for future lunar and interplanetary missions. The spacecraft was launched into a low earth parking orbit, but an inoperative roll gyro prevented Agena restart resulting in Ranger 2 being stranded in low earth orbit. The orbit decayed and the spacecraft reentered Earth's atmosphere on 20 November 1961.

1962 January 26 - . 20:30 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 121D (AA3) / Agena B 6003 (AA3). FAILURE: Agena B second stage guidance system failure. Failed Stage: 2.
  • Ranger 3 - . Payload: NASA P-34 (RA-3). Mass: 327 kg (720 lb). Nation: USA. Agency: NASA. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 3-4-5. USAF Sat Cat: 221 . COSPAR: 1962-Alpha-1. Lunar impact probe; missed the moon by 36,874 km and went into solar orbit. A malfunction in the booster guidance system resulted in excessive spacecraft speed. Reversed command signals caused the telemetry antenna to lose earth acquisition, and mid-course correction was not possible. Some useful data were obtained from the flight. Of four scientific experiments only one was partially completed: gamma-ray readings of the lunar surface. Attempts to relay television pictures of the moon and to bounce radar signals off the moon at close range were unsuccessful.

1962 April 23 - . 20:50 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 133D (AA4) / Agena B 6004 (AA4).
  • Ranger 4 - . Mass: 328 kg (723 lb). Nation: USA. Agency: NASA. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 3-4-5. Decay Date: 1962-04-26 . USAF Sat Cat: 280 . COSPAR: 1962-Mu-1. Ranger IV was launched by an Atlas-Agena B booster from the Atlantic Missile Range, attained a parking orbit, and was fired into the proper lunar trajectory by the restart of the Agena B engine. Failure of a timer in the spacecraft payload caused loss of both internal and ground control over the vehicle. The Goldstone Tracking Station maintained contact with the spacecraft until it passed behind the left edge of the moon on April 26. It impacted at a speed of 9,617 km per hour, the first American spacecraft to land on the lunar surface. The Agena B second stage passed to the right of the moon and later went into orbit around the sun. Lunar photography objectives were not achieved.

1962 July 22 - . 09:21 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 145D (AA5) / Agena B 6901 (AA5). FAILURE: Destroyed by range safety.. Failed Stage: U.
  • Mariner 1 - . Payload: Mariner R-1. Mass: 200 kg (440 lb). Nation: USA. Agency: NASA. Program: Mariner. Class: Venus. Type: Venus probe. Spacecraft: Mariner 1-2. Decay Date: 1962-07-22 . COSPAR: F620722A. Summary: Venus probe..

1962 August 27 - . 06:53 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 179D (AA6) / Agena B 6902 (AA6).
  • Mariner 2 - . Payload: Mariner R-2. Mass: 201 kg (443 lb). Nation: USA. Agency: NASA. Program: Mariner. Class: Venus. Type: Venus probe. Spacecraft: Mariner 1-2. USAF Sat Cat: 374 . 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.

1962 October 18 - . 16:59 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 215D (AA7) / Agena B 6005 (AA7).
  • Ranger 5 - . Mass: 340 kg (740 lb). Nation: USA. Agency: NASA. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 3-4-5. USAF Sat Cat: 439 . COSPAR: 1962-B-Eta-1. 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....

1964 January 30 - . 15:49 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 199D (AA8) / Agena B 6008 (AA8).
  • Ranger 6 - . Payload: RA-6. Mass: 362 kg (798 lb). Nation: USA. Agency: NASA; JPL. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 6-7-8-9. Decay Date: 1964-02-02 . USAF Sat Cat: 747 . COSPAR: 1964-007A. Impacted Moon but TV camera malfunctioned. A midcourse trajectory correction was accomplished early in the flight by ground control. On February 2, 1964, 65.5 hours after launch, Ranger 6 impacted the Moon on the eastern edge of Mare Tranquillitatis (Sea of Tranquility). No camera data were obtained, probably because of failure due to an arc-over in the TV power system when it inadvertently turned on during the period of booster-engine separation.

1964 April 14 - . 21:42 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas D. LV Configuration: Atlas D 263D.
  • 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.

1964 July 28 - . 16:50 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 250D (AA9) / Agena B 6009 (AA9).
  • Ranger 7 - . Mass: 362 kg (798 lb). Nation: USA. Agency: NASA; JPL. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 6-7-8-9. Decay Date: 1964-07-31 . USAF Sat Cat: 842 . COSPAR: 1964-041A. First successful Ranger; returned 4,308 photos before lunar impact. The Atlas- Agena B inserted the Agena and Ranger into a 192 km altitude Earth parking orbit. Half an hour after launch a second burn of the Agena engine injected the spacecraft into a lunar intercept trajectory. After separation from the Agena, the solar panels were deployed, attitude control activated, and spacecraft transmissions switched from the omniantenna to the high-gain antenna. The next day the planned mid-course maneuver was successfully initiated at 10:27 GMT. The only anomaly during flight was a brief loss of two-way lock on the spacecraft by the DSIF tracking station at Cape Kennedy following launch.

    Ranger 7 reached the Moon on 31 July. The F-channel began its one minute warm up 18 minutes before impact. The first image was taken at 13:08:45 GMT at an altitude of 2110 km. Transmission of 4,308 photographs of excellent quality occurred over the final 17 minutes of flight. The final image taken before impact had a resolution of 0.5 meters. The spacecraft encountered the lunar surface in direct motion along a hyperbolic trajectory, with an incoming asymptotic direction at an angle of -5.57 degrees from the lunar equator. The orbit plane was inclined 26.84 degrees to the lunar equator. After 68.6 hours of flight, Ranger 7 impacted in an area between Mare Nubium and Oceanus Procellarum (subsequently named Mare Cognitum) at approximately 10.35 S latitude, 339.42 E longitude. Impact occurred at 13:25:48.82 GMT at a velocity of 2.62 km/s.


1964 September 5 - . 01:23 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena B. LV Configuration: Atlas Agena B 195D (AA10) / Agena B 6501 (AA10).
  • OGO 1 - . Payload: OGO A. Mass: 487 kg (1,073 lb). Nation: USA. Agency: NASA Greenbelt. Class: Earth. Type: Magnetosphere satellite. Spacecraft: OGO. Decay Date: 1980-08-10 . USAF Sat Cat: 879 . 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.

1964 November 28 - . 14:22 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC12. LV Family: Atlas. Launch Vehicle: Atlas Agena D. LV Configuration: Atlas Agena D 288D (AA12) / Agena D 6932 (AA12).
  • 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.

  • Ranger 8 - . Payload: RA-8. Mass: 366 kg (806 lb). Nation: USA. Agency: NASA; JPL. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 6-7-8-9. Decay Date: 1965-02-20 . 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.

  • Ranger 9 - . Payload: RA-9. Mass: 366 kg (806 lb). Nation: USA. Agency: NASA; JPL. Program: Ranger. Class: Moon. Type: Lunar probe. Spacecraft: Ranger 6-7-8-9. Decay Date: 1965-03-24 . 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.

  • FIRE 2 - . Nation: USA. Agency: USAF. Apogee: 817 km (507 mi). Suborbital reentry heating experiment using the FIRE subscale Apollo capsule. 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.

All 21 experiments returned good data. At the time, this was the largest experimental complement ever put into orbit. There were 4 cosmic ray instruments (1 of which included a gamma-ray spectrometer), 4 plasma, 2 trapped radiation, 2 magnetic fields, 5 ionosphere, 3 radio/optical, and 1 micrometeoroid detectors. OGO 3 maintained 3-axis stabilization for 46 days. At that point, an attitude controller failed and the spacecraft was put into a spin on 23 July 1966. The spin period varied from 90-125 seconds. By June 1969, data acquisition was limited to 50% of the orbital path. Routine spacecraft operation was discontinued on December 1, 1969, after which only data from Heppner's experiment (Rubidium + Fluxgate magnetometer) was acquired. By March 1971 spacecraft perigee had increased to 16,400 km and the inclination had increased to 75.8 deg. All spacecraft support terminated on February 29, 1972.
