Sealaunch Demo

NSSDCA/COSPAR ID: 1999-014A

Description

DemoSat was the first Boeing Sea Launch mission. The Zenit-3SL booster rocket lifted off from the Odyssey floating platform on the equator at 154 degrees W longitude. The DemoSat payload was an instrumented dynamic model of an HS-702 satellite built by Boeing Commercial Space/Kent. Thirteen minutes after launch, the Block DM-SL upper stage completed its first burn and entered a 180 km x 735 km x 1.2 degree parking orbit. A second burn 47 minutes after launch placed the satellite in a 638 x 36,064 km x 1.2 degree geostationary transfer orbit. Three hours later, a third DM-Sl burn lowered the stage's perigee so that it would re-enter quickly.
