MESSENGER Completes Second Flyby of Venus,
Makes Its Way toward First Flyby of Mercury in 33 Years

NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft swung by Venus for the second time early this evening for a gravity assist that shrank the radius of its orbit around the Sun, pulling it closer to Mercury. At nearly 15,000 miles per hour, this change in MESSENGER's velocity is the largest of the mission. [more]
