Engineering model of Proba-V's imager - known as the Structural and Thermal Model (STM) - being prepared for testing by OIP engineers Jorg Versluys and Nico Van Vooren in ESA's Mechanical Systems Laboratory on 15 March 2010. Thermocouples have been added to the STM in advance of it being placed inside a vacuum chamber where it would be subjected to space-like hard vacuum and temperature extremes.
