Mercury Flyby 2

Overview

On October 6, 2008, the MESSENGER spacecraft passed a mere 200 kilometers (124 miles) above Mercury's surface for the mission's second flyby of its target planet. The flyby�s primary purpose was to use Mercury for a gravity assist, a crucial encounter needed to enable MESSENGER, in 2011, to become the first spacecraft ever to enter into an orbit around Mercury. Though the gravity assist was the top priority for the flyby, MESSENGER's second flyby of Mercury also provided an opportunity to make significant and exciting science observations and measurements.
