Mercury In 3D Coming Soon
Berlin, Germany (SPX) Mar 21, 2011
Early on 18 March 2011, a spacecraft swung into orbit around Mercury for the first time: NASA's MESSENGER began orbiting the planet at 01:45 CET. The mission carries scientific instruments designed to map Mercury and analyse the structure and composition of its surface. Scientists at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) will analyse the data received from three of the instruments on MESSENGER. As far as the planets of the Solar System are concerned, Mercury ... read more
