NASA will release the first orbital image of Mercury's surface, including previously unseen terrain, on Tuesday afternoon, March 29. Several other images will be available Wednesday, March 30, in conjunction with a media teleconference at 2 p.m. EDT to discuss these initial orbital images taken from the first spacecraft to orbit Mercury. NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging, or MESSENGER, entered orbit March 17 after completing more than a dozen laps within the...

Data from its first three days in orbit about Mercury have confirmed the initial assessment of the spacecraft team that MESSENGER is in its intended orbit and operating nominally. "The team is relieved that things have gone so well, but they remain busy as they continue to configure the spacecraft for orbital operations and monitor its health and safety in the new environment," says MESSENGER Project Manager Peter Bedini, of the Johns Hopkins University Applied Physics Laboratory in Laurel,...

PHOENIX, March 18, 2011 /PRNewswire/ -- On the evening of March 17, 2011, NASA's MESSENGER spacecraft fired its main engine for 15 minutes to perform a Mercury capture maneuver and became the first spacecraft in history to orbit the innermost planet to the Sun. This event marks the culmination of over six and a half years of interplanetary cruise in an ever-tightening spiral toward Mercury, where MESSENGER performed six gravity-assist planet flybys: one of Earth, two of Venus, and three...

After a journey spanning more than six years and nearly five billion miles, the Messenger spacecraft successfully entered orbit around Mercury at approximately 9pm EDT Thursday, NASA officials have announced. Messenger, which launched on August 3, 2004 from Cape Canaveral Air Force Station in Florida, is the first spacecraft to ever enter Mercury's orbit, and the first of any kind to visit the smallest planet in the solar system since the Mariner project some three-plus decades ago. "For the...

A small NASA spacecraft called Messenger will enter into the orbit of the planet Mercury on St. Patrick 's Day, circling as close as 125 miles from the rocky planet's surface and revealing parts of Mercury never before seen by human eyes. Coincidentally, a few days earlier will be the best time this year for people here on Earth to see Mercury with the naked eye, the Associated Press reported. Despite being the planet closest to the sun, some scientists believe Mercury contains tons of ice in...

The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...
