Nasa Tests Earth Camera Prototype for Terra Spacecraft

26 October 2010

Nasa's Jet Propulsion Laboratory and the University of Arizona's College of Optical Sciences have successfully conducted the first test flight of a prototype Earth camera for the Terra spacecraft.

The multiangle spectropolarimetric imager (MSPI) is a multidirectional multiwavelength, high-accuracy polarisation camera for the spacecraft.

An airborne prototype version of the instrument, the AirMSPI has been tested on one of Nasa's high-altitude ER-2 Earth Resources aircraft during a two-hour flight from the Dryden Aircraft Operations Facility.

Terra, a next-generation satellite, will survey the impacts of aerosols and clouds on global climate change.
