Vega-C | TRUTHS

TRUTHS

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.

Vega-C

Vega-C is a single-body rocket nearly 35 m high with that weighs 210 tonnes on the launch pad. As with Vega, its main elements are three solid-propellant stages, an upper stage powered by a reignitable liquid-propellant engine and a payload fairing. Vega-C's P120C first stage replaces Vega’s smaller P80 to provide a significant increase in thrust at liftoff. It is also used as boosters (2 or 4) for the Ariane 6 rocket.
