ESA's Proba-1 Microsatellite Celebrates a Decade On-orbit

Small But Agile Proba-1 Reaches 10 Years in Orbit, ESA

"A good photographer needs agility. So it is with ESA microsatellite Proba-1, which turns in space to capture terrestrial targets. Celebrating its tenth birthday this week, Proba-1's unique images are used by hundreds of scientific teams worldwide. A technology demonstrator turned into an Earth observation mission, the microsatellite - just a cubic metre in volume - has acquired nearly 20, 000 environmental science images with its main Compact High Resolution Imaging Spectrometer (CHRIS), used by a total of 446 research groups in 60 countries."
