2002-053A
SES satellite ordered 1998 from Aerospatiale. It is the first Spacebus 4000. The Spacebus 4000 is also called Spacebus 3000B3S; but is different from the Spacebus 3000B3, e.g. Eurasiasat 1. 1K has the Spacebus 3000 avionics, unlike later SB4000 model. Astra 1K is to replace Astra 1B, and provide extra capacity for eastern Europe. It will also carry Ka-band capacity to back up Astra 1H. The Ku-band 10.7-11.7 GHz payload provides pan-European coverage. Beams cover UK/Ireland, continental Europe, and European CIS. Mass will be 5250 kg.
SCS (Societe Commune des Satellites) formed 1998 to merge Alcatel and Aerospatiale/Cannes built the satellite.
Launch mass 4650 kg.
MES-2 terminated after 1s with excessive fuel flow to DM engine followed by SC sep. DM vented fuel shortly after and reentered empty on Nov 28. Astra 1K was deorbited on command.
Reentry time based on TLEs was around 0120 UTC, not 0200 UTC as reported by SES.
The spacecraft was not registered by Luxembourg; an Alcatel fact sheet described Alcatel's role as a ground delivery of the satellite combined with provision of on-orbit testing (as opposed to on-orbit delivery). This implies that the owner of the satellite during the launch was SES and not Alcatel even if the former delegated operational control to the latter, and thus that Luxembourg was a launching state together with Russia.
