COROT (Convection, Rotation and Planetary Transits), a CNES satellite for astroseismology and extrasolar planet transit photometry search, using the Proteus bus. 600 kg mass. Launch mid 2006 by Soyuz-2-1b No. 001 from Baykonur within 14D23 upper stage engine and Fregat No. 1013 fourth stage and S (4m) fairing. ESA provides the 0.30m telescope. There are two 0.27m afocal off-axis parabolic mirrors.
Launch mass 626 kg. (605 kg PK). Size 4.10m long 1.98m dia. Box-cyl + 2 panels. Height 9m in orbit. Span unknown.
Prop system with 90m/s delta-V. The telescope is by LAM/Marseille, the detector by LEISA/Paris-Meudon. Control from Toulouse. Spacecraft by Alcatel Alenia Space/Cannes.
After a successful mission the science operations ended in 2012. The spacecraft's orbit was lowered in Jan 2014 and the vehicle was decommissioned in Jun 2014.
