Un altro bel lancio per VEGA :clap:

La costellazione Copernicus è un programma decisamente interessante anche, ma non solo, per la decisione di rendere pubblici i dati acquisiti.

Mentre si avvicina alla fine della sua vita operativa, Sentinel-2A sperimenta la “visione notturna”.

L’articolo sul sito di ESA.

:newspaper: Sentinel-2 explores night vision

In essence, the current generation of Sentinel-2 satellites, which will also include Sentinel-2D in the future, were never designed to image at night – but the plan is that the follow-on Sentinel-2 Next Generation mission will indeed do so over certain regions.

As Sentinel-2A approaches the end of its operational life, it continues to support the operational Sentinel-2 mission – but, in addition, engineers and scientists are using some its remaining time in orbit to test new ideas for the future and to prepare for the Next Generation mission. One such experiment has been to see how it would fare when switching it on at night.
