SCIENCE RESULTS AND NEW IMAGES FROM MESSENGER'S THIRD MERCURY FLYBY

Date: September 23, 2009, at 1 p.m. EDT


Introduction:

On September 29, 2009, the MESSENGER spacecraft will pass 228 kilometers (141.7 miles) above Mercury's surface, for the mission's third flyby of its target planet. The flyby’s primary purpose is to use Mercury for a gravity assist, a crucial encounter needed to enable MESSENGER, in March 2011, to enter into an orbit around Mercury. MESSENGER's third flyby of Mercury also provides an opportunity to continue to make significant and exciting science observations and measurements. During the third Mercury encounter, MESSENGER’s camera system will again image much of the planet seen on the second Mercury flyby, but it will also view another small portion of Mercury's surface never previously seen by spacecraft. Some of the most interesting areas on Mercury's surface will be targets of simultaneous spectral measurements and high-resolution color images.
