2015 began and ended with two pioneering missions: IXV, the Intermediate Experimental Vehicle, proving Europe's ability to return autonomously from space, and LISA Pathfinder, which set out in December to test the technologies needed to detect gravitational waves and, with them, a new way to look at our Universe! But a lot has happened in between... More European astronauts have visited space and more satellites are beefing up Galileo and ESA's Earth Observation programme!
