• ROCSAT-1 - . Mass: 400 kg (880 lb). Nation: Taiwan. Agency: NSPO. Manufacturer: TRW. Class: Earth. Type: Seismology satellite. Spacecraft Bus: T200. Spacecraft: ROCSAT. USAF Sat Cat: 25616 . COSPAR: 1999-002A. Apogee: 523 km (324 mi). Perigee: 479 km (297 mi). Inclination: 34.96 deg. Period: 94.63 min.

  Taiwan's first satellite, with experimental communications, ocean imagery, and ionospheric studies instruments. The Primex OAM placed itself and the payload into an elliptical transfer orbit. A second OAM burn circularized the orbit, and ROCSAT separated into a 588 x 601 km x 35.0 deg orbit.

• USA 142 - . Payload: DSP-1 Block 18 F19. Mass: 2,380 kg (5,240 lb). Nation: USA. Agency: USAF. Manufacturer: TRW. Class: Surveillance. Type: Early warning satellite. Spacecraft: DSP. USAF Sat Cat: 25669 . COSPAR: 1999-017A. Apogee: 35,800 km (22,200 mi). Perigee: 720 km (440 mi). Inclination: 28.00 deg.

  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.

• Chandra - . Payload: OV-102. Nation: USA. Agency: NASA Huntsville. Manufacturer: TRW. Class: Astronomy. Type: X-ray astronomy satellite. Spacecraft: Chandra. USAF Sat Cat: 25867 . COSPAR: 1999-040B. Apogee: 128,769 km (80,013 mi). Perigee: 20,046 km (12,455 mi). Inclination: 45.10 deg. Period: 3,808.60 min.

  The Chandra Advanced X-ray Astrophysics Facility was one of NASA's four Great Observatories (along with Hubble Space Telescope, Compton Gamma Ray Observatory, and the SIRTF). Chandra will study the composition and nature of galaxies, stellar objects and interstellar phenomena as well as basic issues in theoretical physics using the most sensitive X-ray telescope ever built. The IUS under-performed and placed Chandra in an orbit about 900 km lower than planned. Therefore Chandra's own IPS propulsion system had to be used to make up the difference. The first such manoeuvre was at 01:11 GMT on July 25 when the IPS engines fired for 5 minutes to raise perigee to 1192 km. Further perigee burns on July 31, August 4, and August 7 raised the orbit to its final 10,000 km x 140.000 km. Additional Details: here....

  Final DSP launch. The series was to be replaced by SBIRS, which was in the middle of a troubled development program. The Delta 4H performed well after problems on its first launch. The RL10-powered upper stage made three burns before releasing the early-warning satellite in its final geosynchronous orbit. Total cost of the flight was $700 million, with the DSP worth $400 million. The DSP carried a special 25 kg supplementary payload designed to detect extremely small nuclear tests in space. The payload was required by a secret White House/National Security Council directive to detect any attempted covert nuclear tests by Iran or North Korea.
