MESSENGER Set for Historic Mercury Flyby
NASA will return to Mercury for the first time in almost 33 years on January 14, 2008, when the MESSENGER spacecraft makes its first flyby of the
Sun’s closest neighbor, capturing images of large portions of the planet never before seen. The probe will make its closest approach to Mercury at
2:04 p.m. EST that day, skimming 200 kilometers (124 miles) above its surface. This encounter will provide a critical gravity assist needed to keep
the spacecraft on track for its 2011 orbit insertion around Mercury.
“The MESSENGER Science Team is extremely excited about this flyby,” says Dr. Sean C. Solomon, MESSENGER principal investigator, from the Carnegie
Institution of Washington. “ We are about to enjoy our first close-up view of Mercury in more than three decades, and a successful gravity assist
will ensure that MESSENGER remains on the trajectory needed to place it into orbit around the innermost planet for the first time.”
