The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, or ‘corona’, the source of the solar wind and space weather. Usually, the corona can only be glimpsed for a few minutes during terrestrial total solar eclipses. Proba-3 aims to reproduce such eclipses for up to six hours at a time, in a highly

Satellite communication underpins everyday life, enabling fundamental improvements not just in communication, but also in transport, healthcare, safety and security, and environmental services. The Advanced Research in Telecommunications Systems (ARTES) 4.0 programme enables European and Canadian industry to explore, through research and development, innovative concepts that stimulates the wider economy, creating new business and jobs across nearly every industry. ARTES 4.0 supports the production of market-leading and cutting-edge products and services within a fiercely competitive global satellite communications market.
