Sentinel-2A

European optical imaging satellite

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. It will perform terrestrial observations in support of services such as forest monitoring, land cover changes detection, and natural disaster management.[4]

Quick Facts Mission type, Operator ...

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

Mission history

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.[5]

Orbital operation

The satellite captured its first image 100 hours after launch, making a 290 km wide swath from Sweden through Central Europe to Algeria.[6][7]: 8  Commissioning occurred in October 2015.[7]: 8 

Between 20 and 23 January 2017 the spacecraft suffered a mission planning anomaly which resulted in loss of data from the Multi-Spectral Imager.[8]
