A new satellite destined to be Europe’s prime mission for monitoring and tracking carbon dioxide emissions from human activity is being put through its paces at ESA’s Test Centre in the Netherlands.

A telecommunications satellite that can be reprogrammed in-orbit, offering unprecedented mission reconfiguration capacity, has successfully passed its in-orbit acceptance review.

Solar Orbiter is returning to Earth for a flyby before starting its main science mission to explore the Sun and its connection to ‘space weather’. During the flyby Solar Orbiter must pass through the clouds of space debris that surround our planet, making this manoeuvre the riskiest flyby yet for a science mission.
