NASA spacecraft to visit Mercury
Published: Jan. 10, 2008 at 1:50 PM
On Monday, the Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, called MESSENGER, will make the first of three flights past the planet, NASA said Thursday in a release.
MESSENGER's cameras and other instruments will collect more than 1,200 images and make other observations during the mission. It will make the first up-close measurements since Mariner 10 spacecraft's third flyby on March 16, 1975.
"This is raw scientific exploration and the suspense is building by the day," Alan Stern, associate administrator for NASA's Science Mission Directorate said in a statement. "What will MESSENGER see? Monday will tell the tale."
NASA said the visit will provide a "critical gravity assist needed to keep the spacecraft on track for its March 2011 orbit insertion, beginning an unprecedented yearlong study of Mercury." The flyby also will gather essential data for mission planning.
MESSENGER, launched in 2004, is slightly more than halfway through its 4.9 billion-mile journey.

A glow appears as the Boeing Delta II rocket with its MESSENGER spacecraft on top starts its mission from Launch Pad 17-B, Cape Canaveral Air Force Station on August 3, 2004. MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) is on a seven-year, 4.9-billion-mile journey to the planet Mercury. The spacecraft will fly by Earth, Venus and Mercury several times, as well as circling the sun 15 times, to burn off energy before making its final approach to the inner planet on March 18, 2011. MESSENGER was built for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. UPI Photo/NASA)
