In preparation activity at Baikonur Cosmodrome, the Fregat M upper stage undergoes a fit-check with the adapter on which MetOp-B will be installed for this European weather satellite’s Soyuz launch on May 23.
The Fregat M upper stage for Starsem’s Soyuz launch of the MetOp-B weather satellite is undergoing its checkout in preparation for a May 23 liftoff from Kazakhstan’s Baikonur Cosmodrome on the Arianespace affiliate company’s 25th commercial mission.
Built by Russia’s Lavochkin Research and Production Association, the Fregat M stage is an autonomous and highly flexible orbital vehicle that can be restarted up to 20 times in flight – enabling it to carry out complex mission profiles.
For Starsem’s upcoming flight, Fregat will place MetOp-B into polar orbit, joining the nearly identical MetOp-A spacecraft – which was launched in October 2006 by Starsem on another Soyuz mission from Baikonur Cosmodrome.
A total of three MetOp-series spacecraft are being developed as a joint undertaking between the European Space Agency and EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites), providing continuous weather observations until 2020.
The upcoming Starsem launch will use a Soyuz 2 modernized version of Russia’s medium-lift workhorse launcher, which also is in service with Arianespace at the Spaceport in French Guiana.
