Kiritimati Kiritimati (Christmas Island) in the Pacific Ocean was originally selected by Von Braun in his Collier magazine series of the early 1950's as an ideal equatorial launch site. A half century later, Boeing Sea Launch used an offshore location for orbital launches. The launch platform was a seagoing converted Norwegian offshore oil rig. Between missions it was berthed in Long Beach, California. It was towed to a location off Kiritimati for launches of the Ukrainian Zenit-3 launch vehicle. More...

Payload: HS 702. Mass: 4,500 kg (9,900 lb). Nation: USA. Agency: SeaLaunch. Manufacturer: Kent. Class: Technology. Type: Navigation technology satellite. USAF Sat Cat: 25661 . COSPAR: 1999-014A. Apogee: 36,045 km (22,397 mi). Perigee: 658 km (408 mi). Inclination: 0.7000 deg. Period: 645.00 min. The first Boeing Sea Launch mission. The Zenit-3SL lifted off from the Odyssey floating platform on the equator at 154 degrees West longitude. The DemoSat payload was an instrumented dynamic model of an HS-702 satellite built by Boeing Commercial Space/Kent. 13 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 DemoSat in a 638 km 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.
