Mission details:

• Bonum is a subsidiary of Media Most, a major private Russian media group. They already operate pay TV from Gals 1, Gals 2 and TDF 2. The contract calls for in-orbit delivery together with the control center and training of the staff.
• 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.
• Television broadcasting; 8 Ku-band, Siberia or Europe, selected.
