2000-F02
The first ICO Global Communications satellite was lost when its Zenit-3SL launch vehicle failed on Mar 12. ICO F-1 was a 2750 kg Hughes HS-601M satellite and would have entered a 10300 km x 45 deg circular orbit. The Zenit-3SL vehicle took of from Boeing Sea Launch's Odyssey platform in the Pacific at 154W 0N. The second stage shut down 7 min into flight because of a prelaunch commanding error in the vernier system, A second stage valve remained open and by the time of ignition had lost more than 60 percent of its pressure. The satellite fell in the South Pacific, possibly south of Pitcairn. ICO's satellites carry multiple spot beams for mobile communications.
The satellite fell in the ocean 4300 km from the launch site in the S Pacific, perhaps around 25S 130W.
Planned orbit was 10390 x 10390 x 45. Presumably MECO-1 orbit was planned to be around 200 x 10390 x 40.
