Solar Sailing and Barnstorming Mercury

NASA MESSENGER Sets Record for Accuracy of Planetary Flyby

"By using solar sailing - rotating the spacecraft and tilting its solar panels to use the very small pressure from sunlight to alter the spacecraft's trajectory - MESSENGER navigators have achieved a new record for the smallest miss distance between the intended and actual closest approach distance during a flyby of a planet other than Earth. On October 6, 2008, the probe flew 199.4 kilometers (123.9 miles) above the surface of the planet. "Our goal was to fly 200 kilometers from the planet's surface, and we missed that target by only 0.6 kilometers," explained MESSENGER Mission Design Lead Jim McAdams."
