Description
NASA's MESSENGER Discovery mission used one Earth, two Venus, and three Mercury gravity assists to become the first spacecraft to orbit Mercury, then mapped and characterized the planet for more than four years.
Destination
Mercury orbit from 18 March 2011 to 30 April 2015 for global mapping and study of the planet’s surface composition, geology, internal magnetic field, exosphere, and polar water ice; the first spacecraft to orbit Mercury, ending in a controlled impact after propellant depletion
End Date
2015-04-30
Launch Site
Outcome
Success. MESSENGER became the first spacecraft to orbit Mercury, globally mapped the planet, characterized its composition and magnetic field, documented its geological history, and confirmed that its polar deposits are dominated by water ice. After exhausting usable propellant, it completed the mission with a predicted impact on Mercury on April 30, 2015.
