Mission description

TRUTHS (Traceable Radiometry Underpinning Terrestrial- and Helio-Studies) is a a ‘standards laboratory in space’, setting the ‘gold standard’ reference for climate measurements. Carrying a cryogenic solar absolute radiometer and a hyperspectral imaging spectrometer as well as a novel onboard calibration system, TRUTHS is designed to make continuous measurements of incoming solar radiation and reflected radiation to evaluate Earth’s energy-in to energy-out ratio.

Ariane Launch Area 1 (ELV)

Guiana Space Centre, French Guiana

The Guiana Space Centre is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
