Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...

BONUM Chronology


1998 November 22 - . 23:54 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. Launch Pad: SLC17B. LV Family: Delta. Launch Vehicle: Delta 7925-9.5. LV Configuration: Delta 7925-9.5 D263.
  • BONUM-1 - . Nation: Russia. Agency: Telenor. Manufacturer: El Segundo. Program: BONUM. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 376. USAF Sat Cat: 25546 . COSPAR: 1998-068A. Apogee: 35,794 km (22,241 mi). Perigee: 35,778 km (22,231 mi). Inclination: 0.2000 deg. Period: 1,436.10 min. BONUM-1 provided domestic Russian television service for Media Most, a Moscow media enterprise, broadcasting 50 channels to western Russia from a geostationary orbit at 36 degrees E. Mass was 1426 kg at launch, 800 kg of that propellant. BONUM-1 carried 8 Ku-band transponders. The Delta upper stage raised the initial 157 km x 189 km at 29.2 degree parking orbit to 159 km x 1304 km and then 1228 km x 1683 km at 26.7 degrees. A Thiokol Star 48B solid third stage boosted BONUM-1 to a 1285 x 36703 km x 19.5 degree geostationary transfer orbit, with the Thiokol Star 30 apogee kick motor placing the satellite in its final geostationary orbit. After separation of the spacecraft, the Delta made a final depletion burn to lower its orbit to 274 km x 1552 km x 25.6 degree to ensure it would quickly decay and burn up in the atmosphere. Geostationary at 35.9 degrees E. From 8 August 2000 position was 56.0 degrees E. Positioned in geosynchronous orbit at 36 deg E in 1998-1999 55 deg E in 2000. As of 5 September 2001 located at 56.03 deg E drifting at 0.016 deg W per day. As of 2007 Mar 10 located at 55.94E drifting at 0.008W degrees per day.
