Last night a crucial step in the European Space Agency’s eclipse-making Proba-3 mission was completed: the two spacecraft, flying jointly since launch, have successfully separated. This leaves them ready to begin their cosmic dance in the world’s first-ever precision formation-flying mission. Read more »

In future missions to Mars, astronauts will need to maximise the use of all resources available on site to produce essential supplies like oxygen, water and fuel. A team from Spanish technological centre Tekniker and the University of Cantabria is developing a system that uses sunlight to turn carbon dioxide and wastewater into methane, which can be used as fuel.

A team of researchers from two universities in the Philippines made use of ESA’s Large Diameter Centrifuge to test the growth of bone cells in hypergravity. The results of their experiment could improve bone implant technology, as well as help support seaweed farming communities across the country. Read more »

Four pioneering ESA Technology CubeSats reentered Earth’s atmosphere over the last few months. Each was only about the size of a shoebox or smaller, but despite their diminutive dimensions the missions left an outsize legacy in terms of demonstrating innovative space technology, industrial capacity building and scientific data return.  Read more »

A key element of ESA’s role as Europe’s space agency is the expansion of space knowhow, by encouraging new actors into the field. Case in point: a Polish software company previously specialising in smartphone apps took on the challenge of designing the operating system for the main instrument of Proba-3 – an ambitious double spacecraft mission to reveal secrets of the Sun’s fiery atmosphere, the corona.

Video: 00:02:32  ESA’s eclipse-making Proba-3 double satellite mission has made it to space! Learn more about Proba-3 from the mission team as they bid farewell to their spacecraft, while ESA's Director General Josef Aschbacher wishes the team the best of luck. The latest member of ESA’s family of in-orbit demonstration missions, Proba-3 is in fact two spacecraft being launched together, which will perform precise formation flying, accurate to a single millimetre, about the thickness of an average fingernail. To prove their performance, Proba-3 has been devoted to an ambitious scientific goal. The pair will line up precisely with the Sun 150 m apart so that one casts a precisely controlled shadow onto the other. By blocking out the fiery disc of the Sun, Proba-3’s ‘Occulter’ spacecraft will mimic a terrestrial total solar eclipse, to open up views of the Sun’s faint surrounding atmosphere, or ‘corona’, which is a million times fainter than its parent star. Proba-3’s second ‘Coronagraph’ spacecraft hosts the optical instrument that will observe the solar corona. Read more »
