ENVISION on-board application software development (ECSS Cat.B)

TELETEL has signed a multi-million Euro contract to design, develop, validate and qualify the complete application software of the ENVISION spacecraft.

EnVision is a European Space Agency (ESA) orbiter mission, in partnership with NASA, scheduled to launch in 2032 to conduct a comprehensive, holistic study of Venus. It will investigate the planet’s interior, surface, and atmosphere to understand how and why Venus and Earth evolved differently, specifically focusing on its current geological activity and climate.
