The MESSENGER spacecraft launched from Cape Canaveral on August 3, 2004 and returned to Earth for its first gravity boost on the way to Mercury a year later on August 2, 2005. MESSENGER took hundreds of high-res digital photos during its Earth flyby and they've been sequenced into an amazing movie of Earth rotating over 24 hours as the spacecraft swung past at thousands of miles per hour.
