Proba: Proba 2

PROBA Format 4:3 Proba was launched as a technology demonstrator within ESA's General Support Technology Programme. Once in orbit, however, the small satellite's unique capabilities and performance made it evident that it could make big contributions to science and so its nominal lifetime was extended to serve as an Earth Observation mission. Proba 2 is due for launch in 2009 as a secondary satellite in the SMOS earth observation mission.
