WASHINGTON - For the first time, Earth has a regular orbiting eye- in-the-sky spying on planet Mercury. NASA's spacecraft Messenger successfully veered into a pinpoint orbit Thursday night after a 6 1/2-year trip and 4.9 billion miles and tricky maneuvering to fend off the gravitational pull of the sun. It is the fifth planet in our solar system that NASA has orbited, in addition to the Earth and the moon.
WASHINGTON | America's first man in space, Alan Shepard, is honored on a new Forever postage stamp being issued Wednesday at the Kennedy Space Center. The stamp is part of a two-stamp set recalling Shepard and the Messenger Mission, the first spacecraft to orbit Mercury. The stamps are valid for first-class mail. The issuance marks the 50th anniversary of America's first manned space flight.
WASHINGTON, June 16, 2011 /PRNewswire-USNewswire/ -- NASA scientists are making new discoveries about the planet Mercury. Data from MESSENGER, the first spacecraft to orbit Mercury, is giving scientists important clues to the origin of the planet and its geological history and helping them better understand its dynamic interior and exterior processes.

Traveling into outer space? Don't forget your quilt. In this case, the traveler is the Mercury Messenger spacecraft. It was launched into the heavens Aug. 2, aimed toward the planet Mercury. It's a 5 billion-mile trip, not a direct flight; it has to do-si-do with Earth, Venus and Mercury a couple of times before it gets to orbit Mercury. The Messenger will arrive at its destination in March 2011. It is the first spacecraft to orbit Mercury.
