For its 10th and final launch of the year — and the fifth in 2020 with the Soyuz medium launcher — Arianespace will send the CSO-2 Earth observation satellite, intended for defense and security applications, into Sun-synchronous orbit. CSO-2 will be launched for the French CNES (Centre National d’E...
The CSO-2 (Composante Spatiale Optique-2) satellite is the second of three new-generation high-resolution optical imaging satellites for the French military, replacing the Helios 2 spy satellite series.
Launched called success on webcast, Arianespace CEO and head of Roscosmos both tweeted that sat is in planned orbit
Liftoff
The 2.1a version includes conversion from analog to digital flight control system and uprated engines on the booster and the first stage with improved injection systems. The new digital flight control and telemetry systems allow the rocket to launch from a fixed rather than angled launch platform and adjust its heading in flight. A digital control system also enables the launch of larger commercial satellites with wider and longer payload fairings such as the ST-type fairing. These fairings introduce too much aerodynamic instability for the old analog system to handle. This stage continues to use the RD-0110 engine. The 2.1a/ST version is sometimes called Soyuz ST-A.
Progress Rocket Space Centre, formerly known as TsSKB-Progress, is a space science and aerospace research company which is known for manufacturing launch vehicles and satellites. Most notably, Progress Rocket Space Centre is the manufacturer of Soyuz launch vehicles.
