One of these, LYRA, is a UV-meter that can draw a timeline of the radiation "behaviour" of the sun. The other, the SWAP telescope, constructs a film using images of the sun's activity. The satellite, which uses one-twentieth of the power of an average refrigerator, cost €18 million for development and construction.
The Proba-2 launch comes eight years after launch of Proba-1, Belgium's first satellite, which is still in orbit. The satellite will be transported together with the ESA's SMOS satellite. Data from Proba-2 will be processed in Redu in the Ardennes.
