MESSENGER, MErcury Surface, Space ENvironment, GEochemistry and Ranging, is an unmanned NASA and APL spacecraft.[1] It is orbiting and studying the planet Mercury.[1] It was launched on August 3, 2004[1][2] at Cape Canaveral Air Force Station. It was aboard a Boeing Delta II rocket.[2] After launch, the probe did several fly-bys and deep space manoeuvres to gain the right trajectory and speed.[1] 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.[1][3] 100% mapping was completed in March 2013 and the probe continued its studies.
