There's no air to breathe, it's 400 degrees Celsius and you are six long years away from home. Welcome to Mercury, the smallest and perhaps most mysterious planet in the Solar System. The European Space Agency (ESA) is aiming to increase our knowledge of the Sun's closest neighbor by launching its BepiColombo spacecraft to the planet Mercury in 2014. One of the key challenges faced by the mission is not just getting there, but also how to apply the brakes against the Sun’s gravitational pull when you do... and that's where QinetiQ's solar-electric ion propulsion system comes in. The company has just announced a £23m contract with EADS Astrium for the supply of its system for the BepiColombo mission.
