MESSENGER, MErcury Surface, Space ENvironment, GEochemistry and Ranging, is an unmanned NASA and APL spacecraft. It is orbiting and studying the planet Mercury. It was launched on August 3, 2004 at Cape Canaveral Air Force Station. It was aboard a Boeing Delta II rocket. After launch, the probe did several fly-bys and deep space manoeuvres to gain the right trajectory and speed. It completed 30% mapping of Mercury on January 14, 2008. MESSENGER made one more pass by Mercury in 2009, and on March 18, 2011 began to orbit Mercury. 100% mapping was completed in March 2013 and the probe continued its studies.
