The ESA-developed Sentinel satellite – Sentinel-2A – has launched successfully today, adding a high-resolution optical imaging capability to the European Union’s Copernicus environmental monitoring system. The 1.1 tonne satellite was carried on a Vega rocket from Europe’s Spaceport in Kourou, French Guiana at 01:52 GMT on 23 June (03:52 CEST; 22:52 local time, 22 June). The first stage separated 1 min 52 sec after lift-off, followed by the second stage and fairing at 3 min 37 sec and 3 min 54 sec, respectively, and the third stage at 6 min 32 sec.
After a first ignition, 7 min 42 sec after lift-off, followed by two reignitions, Vega’s upper stage delivered Sentinel-2A into the targeted Sun-synchronous orbit. The satellite separated from the stage 54 min 43 sec into the flight.
Telemetry links and attitude control were then established by controllers at ESA’s operations centre in Darmstadt, Germany, allowing activation of Sentinel’s systems to begin. The satellite’s solar panel has already been deployed. After this first phase, which typically lasts three days, controllers will begin checking and calibrating the instruments to commission the satellite. The mission is expected to begin operations in three or four months.
