Copernicus Satellite Sentinel-1A Rides Into Space
Sentinel-1 is the first in the family of satellites for Europe’s Copernicus program. It carries an advanced radar to scan Earth’s surface in all weather conditions day and night. Cameras mounted on the Soyuz Fregat upper stage that sent Sentinel-1A into space on April 3 captured this footage from liftoff to separation. The 2.3 tonne satellite lifted off on a Soyuz rocket from French Guiana. The first stage separated 118 sec later, followed by the fairing (209 sec), stage 2 (287 sec) and the upper assembly (526 sec). After a 617 sec burn, the Fregat upper stage delivered Sentinel into a Sun-synchronous orbit at 693 km altitude. The satellite separated from the upper stage 23 min 24 sec after liftoff.
