Nasa gears up for Maven mission to Mars
US space agency Nasa is preparing to launch its Mars Atmosphere and Volatile Evolution (Maven) spacecraft next month to probe the atmosphere on the Red Planet.
Maven will study Mars to help scientists work out how it managed to lose an atmosphere that was once believed to be thicker than that of Earth.
The mission is due to launch on 18 November from Florida and arrive on Mars on 22 September 2014.
