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.


European Space Agency mission to study Venus' atmosphere, geological activity, and climate.

Atmospheric Remote sensing Infrared Exoplanet Large survey mission (ARIEL) is an ESA telescope. During its 4-year mission, ARIEL will observe 1000 planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. For a selected number of exoplanets, ARIEL will also perform a deep survey of their cloud systems and study seasonal and daily atmospheric variations.
