The spacecraft was delivered to its final orbit in a complex series of five engine burns by three rocket stages. The Delta's second stage demonstrated its restart capability in 4 burns: Burn 1 placed the rocket and payload into a low circular orbit; Burn 2 raised the apogee to 1400 km; Burn 3 circularised the orbit at 1400 km. The second stage then separated, and Burn 4 lowered the spent stage's perigee to a low altitude to ensure the stage would decay quickly and not add to the space junk already on orbit. Stage 3 burned once to place the payload and its kick motor into a high 1400 km perigee geosynchronous transfer orbit. The Stage 4 Star 30 apogee kick motor circularised the spacecraft's orbit at geostationary altitude. Geostationary at 0.8 degrees W.

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.

  • 2001 Mars Odyssey - . Mass: 725 kg (1,598 lb). Nation: USA. Agency: JPL. Class: Mars. Type: Mars probe. Spacecraft: Mars Odyssey. USAF Sat Cat: 26734 . COSPAR: 2001-013A. The 2001 Mars Odyssey probe (formerly the Mars Surveyor 2001 Orbiter) was the first spacecraft in the revamped NASA Mars Exploration Program. Built by Lockheed Martin Astronautics (Denver) and JPL, the satellite was similar to Mars Climate Orbiter. It carried a 6-meter boom with a gamma ray spectrometer for remote sensing of Martian surface mineralogy, as well as an infrared imager and a radiation environment monitor. The probe had a dry mass of 376 kg and carried 349 kg of propellant. 2001 Mars Odyssey entered a 195 x 215 km x 52 deg parking orbit 10 minutes after launch. After a 12 minute coast the Delta second stage fired again and separated from the third stage, which placed the probe on an Earth escape trajectory into a 0.982 x 1.384 AU x 3.05 deg solar orbit. It escaped Earth's nominal gravitational sphere of influence at around 19:00 GMT on April 10.

    The 2001 Mars Odyssey probe entered Mars orbit on October 24, 2001. The orbit insertion burn with the main 640 N bipropellant N2O4/hydrazine engine began at 0218 GMT lasted 20 min 19 sec. Mass of the spacecraft was then 456 kg, including 79 kg of fuel left. Initial orbit was was 272 x 26818 km x 93.42 deg with periapsis near the Martian north pole. 76 days of aerobraking began on October 26 to slowly circularise the orbit to its 400 km altitude, 2 hour period sun synchronous operational orbit. The solar panels reached 180 deg C as Odyssey skimmed through upper atmosphere of Mars on each orbit.

    After reaching the operational orbit, the probe was to conduct a 917 day mapping program. It was to also serve as a communications relay for American and international landers expected to arrive in 2003/2004. In the Martian orbit, it was to map the distribution of elements and minerals on the surface, the distribution of hydrogen (embedded in water ice) and the radiation environment. The second was to assess the likelyhood of past or present life, and the third was to assess the radiation hazard to manned missions. The three major instruments on board were THEMIS (Thermal Emission Imaging System at the visible and infrared light) for the distribution, at 100 meter resolution, of minerals that form only in the presence of water, GRS (Gamma Ray Spectrometer) for determining hydrogen and other elements, and MARIE (presumably, MArs RadIation Environment) for determining the radiation hazard. THEMIS was to also enable site selection for a future manned landing. THEMIS was expected to provide 15,000 images, each covering 20 x 20 km. GRS carried two neutron monitors also. The gamma rays and neutrons come out of the surface in distinct, element-specific energies, released by cosmic ray bombardment.

Spacecraft: GPS Block 2R. USAF Sat Cat: 28874 . COSPAR: 2005-038A. Apogee: 20,187 km (12,543 mi). Perigee: 20,006 km (12,431 mi). Inclination: 55.0000 deg. Period: 714.50 min. Delayed from December 2004; February 1, March 17, 2005. Moved up from May 20 2005. Then delayed from May 4, July 29, August 26, September 22, 2005. Became operational at 23:30 GMT on 16 December. First GPS Block IIR-M version, which added extra navigation signals for both civil and military users. The NASA-funded L2C tracking demonstration was managed by JPL and explored the use of a new Civilian code signal (L2C). The data was collected with Trimble NetRS receivers L2C-enabled firmware. The sites were globally distributed: South Africa, Norway, Antarctica, Hawaii, and Alaska.

USAF Sat Cat: 29240 . COSPAR: 2006-024A. Apogee: 36,222 km (22,507 mi). Perigee: 184 km (114 mi). Inclination: 25.2500 deg. Period: 639.26 min. The Microsatellite Technology Experiment was a classified mission, believed to be a test of prototype inspect-and-disable satellites that would control the constellation of geostationary satellites on which the world depends for television reception and communications. Each microsatellite, one built by Orbital Sciences, and the other by Lockheed Martin, had a mass of about 250 kg. They were believed to be solar-powered and equipped with propulsion systems that would allow them to rendezvous with geosynchronous satellites. Once they had reached the satellite, they would presumably be capable of destroying, disabling, or jamming them. To deliver the two satellites to near-synchronous orbit, a Naval Research Laboratory liquid propellant bus equipped with a 400 N main engine and solar panels was used.
