A commission of military officers and chief designers reviewed the incident and requested changes to equipment and procedures, especially as regarded liquid oxygen handling. Another source reports that the explosion occurred during the fuelling of the Block E upper stage, and was due to hydrogen peroxide being present in a lox line filter and a confusion between fuel and lox lines. This error had always been possible, but had never happened in the 20 years of use of the booster before the explosion. The launch pad was badly damaged and not put back into service until April 1983.

The failure was caused by a loss of lubricating oil to one of the booster engines, causing the engine to fail approx 200 milliseconds before it was to have shut down on guidance command. The asymmetric thrust pivoted the booster around approximately 180 degrees, where it stabilized in a retrofire attitude with the sustainer engine still firing. It descended back toward earth through its own exhaust flame and exploded a couple of minutes later.

  • USA 52 - . Payload: RME. Mass: 1,040 kg (2,290 lb). Nation: USA. Agency: SDIO. Class: Military. Type: Strategic defense satellite. Spacecraft: RME. Decay Date: 1992-05-24 . USAF Sat Cat: 20497 . COSPAR: 1990-015B. Apogee: 281 km (174 mi). Perigee: 261 km (162 mi). Inclination: 43.1000 deg. Period: 89.90 min. 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.

The Titan 4B placed the IUS upper stages and DSP-1 Block 14 ballistic missile launch detection satellite. payload into a 188 km x 718 km x 28.6 deg parking orbit. The first stage of the IUS burned at 18:14 GMT and put the second stage and payload into a geosynchronous transfer orbit. The IUS second stage fired at 23:34 GMT in order to place the spacecraft in geosynchronous orbit. However, at least one connector remained attached between the stages, and the second stage motor nozzle did not extend properly. When the stage fired, the vehicle tumbled wildly during the burn. Separation of the DSP was achieved. Although it could not perform its primary mission, it did provide a good test case in that the effects of radiation on its systems could be monitored as they underwent twice-daily passages of the Van Allen Radiation Belts. However after some weeks the hydrazine propellant aboard the satellite vented into space due to a broken fuel line. It was believed this had been induced by the wild ride aboard the IUS-2 stage.

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.

The Essaim demonstrator was a system of several micro-satellites (Essaim means 'swarm' in French) for 'analysis of the electro-magnetic environment of the Earth's surface' (electronic intelligence). DGA, the French Ministry of Defence's procurement agency, developed the project. The system also comprised a ground control segment and a ground station for data processing. It was called a 'demonstrator' since the mission's objective was to assess the operational capability of such a system, paving the way for the next generation. The Essaim satellites were based on EADS Astrium's Myriade multipurpose micro-satellite. In early 2000, the DGA awarded the contract for the development, manufacturing of this turnkey system of micro-satellites and associated ground segment. Under the contract, EADS Astrium was also responsible for personnel training and system operations during the three-year life duration of the programme.

The system also include payloads installed on Molniya-orbit signals intelligence satellite (USA 184 and USA 200). The spacecraft carry an infrared telescope with a large focal plane infrared array to monitor large areas of the Earth at once. An internal moving mirror scans the visible disk of the Earth to detect and track possible missile launches. It also has capabilites to track high-altitude aircraft and thermal events on the surface. The new SBIRS network will succeed 23 DSP satellites launched from 1970 to 2007. GEO-1 was inserted into geostationary transfer orbit by the booster and used its own on Leros-1 apogee motor to maneuver into geosynchronous orbit.
