Sentinel-2A

Sentinel-2A is a European optical imaging satellite launched in 2015. It is the first Sentinel-2 satellite launched as part of the European Space Agency's Copernicus Programme. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. Its observations support services such as forest monitoring, land cover change-detection, natural disaster management and water quality monitoring.

On 7 March 2017 the Sentinel-2A was joined in orbit by its sister satellite, Sentinel-2B.

Launch
Sentinel 2A was launched by the Vega VV05 rocket on 23 June 2015 at 01:52 UTC. The satellite separated from the upper stage 54 min 43 s after liftoff.

Orbital operation
The satellite captured its first image 100 hours after launch, covering a 290 km wide swath from Sweden through Central Europe to Algeria. Commissioning occurred in October 2015.

Between 20 and 23 January 2017 the spacecraft suffered a mission planning anomaly which resulted in loss of data from its instrument, the Multi-Spectral Imager.
