French visible astronomy satellite. One launch, 2006.12.27.
European COnvection ROtation and planetary Transits satellite, designed to detect transits of planets down to earth size as they pass in front of their stars, and convection currents on stellar surfaces. The satellite was to use its 27-cm-diameter telescope to scan 120,000 stars during its 30-month mission.
The COROT satellite consisted of :
- A Proteus bus , designed for 500 kg class satellites operating in low earth orbit. COROT was the third mission to use this platform and the associated generic ground control segment after Jason-1 and Calipso.
- The scientific payload, consisting of a 2 mirrors off axis telescope, a visible-range wide field camera, and avionics and software that handled the aperture photometry processing and calculated the angle error measurement data for the platform in fine pointing mode.
Corot had a pointing accuracy of 0.5 arcsec and could downlink 1.5 Gbit of telemetry per day. It would operate in a pure (not sun-synchronous) polar circular orbit (90-degree inclination) at an altitude of 896 km. During alternating 20 and 150 day observation runs the spacecraft would be 3-axis stabilized with asterocentric pointing. The jitter of stars as received by the detector was then less than 0.5 arcsec (0.2 pixel). The seismology channel provided the platform with the angular data feeding the attitude control system.

Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...
Associated Launch Vehicles
Soyuz Russian orbital launch vehicle. The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...

Associated Launch Sites
Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
