An
Ariane 42P successfully launched SPOT 5 from Kourou, pad ELA 2, at
0131 UTC on May 4. The imaging spacecraft will be placed into a
sun-synchronous orbit of 813 km at 98.74 degrees.
The
3030 kg (6666 lbm) Satellite Probatoire de l'Observation de la
Terre (SPOT) spacecraft was built by Astrium, with payloads
provided by Alcatel Space. The satellite has
a 5 year design life, and will have a beginning of life power of
2.350 kW.

The
launch also carried two auxiliary satellites, called IDEFIX, for
France AMSAT. The 6 kg picosats will be placed into orbit without
separating from the third stage. IDEFIX are educational
satellites, involving the transmission of telemetry and
prerecorded vocal messages. They are designed for an orbital life
of 25 to 60 days and will be activated 10 - 15 days after the
launch. Both picosats will transmit NBFM voice recorded messages
and digital telemetry data, the first one on 145,840 MHz and the
other one one 435,270 MHz.
Spot
Image's main shareholders are CNES (35%), private industrial
groups, including Astrium (formerly Matra Marconi Space) which is
prime contractor for the SPOT satellites (23%), the French
National Geographic Institute (IGN - 10%), and shares held by
government and private entities in Belgium, Sweden and Italy (11%).
Only
four Ariane 4 rockets remain in the Arianespace inventory.
