• Lewis - . Payload: SSTI/Lewis. Nation: USA. Agency: NASA, TRW. Manufacturer: Chantilly. Class: Earth. Type: Earth resources satellite. Spacecraft Bus: T200. Spacecraft: Lewis satellite. Decay Date: 1997-09-28 . USAF Sat Cat: 24909 . COSPAR: 1997-044A. Apogee: 134 km (83 mi). Perigee: 124 km (77 mi). Inclination: 97.50 deg. Period: 87.10 min. Reentered Sep 28.

• Lunar Prospector - . Payload: Discovery 3. Mass: 295 kg (650 lb). Nation: USA. Agency: NASA Ames. Manufacturer: Lockheed. Program: Discovery series. Class: Moon. Type: Lunar probe. Spacecraft Bus: LM-100. Spacecraft: Lunar Prospector. Decay Date: 1999-07-31 . USAF Sat Cat: 25131 . COSPAR: 1998-001A.

  The Lunar Prospector was designed for a low polar orbit investigation of the Moon, including mapping of surface composition and possible polar ice deposits, measurements of magnetic and gravity fields, and study of lunar outgassing events. Data from the 1 to 3 year mission will allow construction of a detailed map of the surface composition of the Moon, and will improve understanding of the origin, evolution, current state, and resources of the Moon. After launch, the Lunar Prospector had a 105 hour cruise to the Moon, followed by insertion into a near-circular 100 km altitude lunar polar orbit with a period of 118 minutes. The nominal mission duration was one year.

• 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.

• Ikonos 1 - . Mass: 726 kg (1,600 lb). Nation: USA. Agency: Martin. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft Bus: LM-900. Spacecraft: Ikonos.

  Tracking stations downrange did not pick up the spacecraft. It was later determined that the rocket nose fairing failed to separate four minutes after launch. The extra mass caused the vehicle to reenter over the South Pacific on the first partial orbit. Space Imaging's Ikonos 1 was to have been the first commercial imaging satellite with a high a resolution camera.

• Ikonos - . Mass: 726 kg (1,600 lb). Nation: USA. Agency: SpaceIm. Manufacturer: Lockheed. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft Bus: LM-900. Spacecraft: Ikonos. USAF Sat Cat: 25919 . COSPAR: 1999-051A. Apogee: 679 km (421 mi). Perigee: 678 km (421 mi). Inclination: 98.10 deg. Period: 98.30 min. Commercial / civilian high resolution (1 metre resolution) photograhic satellite..

• Starshine 3 - . Mass: 67 kg (147 lb). Nation: USA. Agency: USAF. Class: Earth. Type: Geodetic satellite. Spacecraft: Starshine. Decay Date: 2003-01-21 . USAF Sat Cat: 26929 . COSPAR: 2001-043A. Apogee: 472 km (293 mi). Perigee: 472 km (293 mi). Inclination: 67.00 deg.

  Possibly last Athena flight. Launch delayed from September 1, 18, 22, 23, 25, 28. This was the first orbital launch from Alaska's Kodiak Island launch site (Foul weather and auroral conditions had delayed the launch many times) . The Lockheed Martin Athena-1's Orbit Adjust Module's (OAM) four MR-107 hydrazine engines fired for 12 minutes to put the payloads in a 237 x 815 km transfer orbit. After a coast to apogee above East Africa, a second burn at 0337 GMT circularized the orbit. USAF Space Test Program satellites Picosat, Sapphire and PCSat were deployed into an 790 x 800 km x 67 deg orbit between 0344 and 0352 GMT; the OAM then made a perigee lowering burn to a 470 x 800 km orbit. Another burn half an orbit later put OAM in a 467 x 474 km orbit, from wish Starshine 3 was deployed. Finally, the OAM made a perigee-lowering depletion burn which left in a 215 x 403 km x 67.2 deg orbit from which would reenter in a few months.

  Starshine-3 was a 90 kg, 0.9 m geodetic sphere that was to be observed by students. The NASA satellite was basically a passive light-reflecting sphere, consisting of 1,500 student-built mirrors (polished by kindergarten and grade school students from many countries) and 31 laser "retroreflectors". A few solar cells provide enough power to send a beacon at 145.825 MHz every minute. Ham operators around the world were expected to obtain signal strengths from which the decay (due to magnetic torque) of its spin rate could be determined. The project was managed by NASA GSFC and Starshine was built by the Naval Research Laboratory.

• PCSat - . Mass: 67 kg (147 lb). Nation: USA. Agency: USN. Class: Communications. Type: Amateur radio communications satellite. Spacecraft: Oscar. USAF Sat Cat: 26931 . COSPAR: 2001-043C. Apogee: 796 km (494 mi). Perigee: 789 km (490 mi). Inclination: 67.00 deg. Period: 100.70 min.

  PCSat (Prototype Communications SATellite) was to act as a relay for UHF/VHF amateur radio transmissions. It was built by the midshipmen at the US Naval Academy. It was to augment the existing worldwide Amateur Radio Automatic Position Reporting System; mass was around 10 kg.

• Picosat - . Mass: 67 kg (147 lb). Nation: USA. Agency: USAF. Manufacturer: Surrey. Class: Technology. Type: Navigation technology satellite. Spacecraft: SSTL-70. USAF Sat Cat: 26930 . COSPAR: 2001-043B. Apogee: 795 km (493 mi). Perigee: 788 km (489 mi). Inclination: 67.00 deg. Period: 100.70 min.

  STP P97-1 Picosat was built by Surrey Satellite for the USAF using a Uosat-type bus. The 68 kg satellite was to test electronic components/systems in space conditions. It carried four test payloads: Polymer Battery Experiment (PBEX), Ionospheric Occultation Experiment (IOX), Coherent Electromagnetic Radio Tomagraphy (CERTO) and an ultra-quiet platform (OPPEX). Called Picosat 9 by some Agencies although not related to other satellites in that series.

• Sapphire - . Mass: 67 kg (147 lb). Nation: USA. Agency: Lockheed. Manufacturer: Stanford. Class: Technology. Type: Navigation technology satellite. Spacecraft: Sapphire. USAF Sat Cat: 26932 . COSPAR: 2001-043D. Apogee: 796 km (494 mi). Perigee: 790 km (490 mi). Inclination: 67.10 deg. Period: 100.70 min. SAPPHIRE (a US DoD-funded microsatellite) was built by Stanford University students and carried experimental infrared horizon sensors, a voice synthesizer and a digital camera. The satellite was about 0.5m in size and had a mass of 16 kg..
