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...

Scientists are excited about solving some of the mysteries surrounding our smallest and hottest planet; the findings are expected to broaden our understanding of rocky planets, more and more of which are being discovered in other solar systems At 8:45 p.m. EDT on March 17, the MESSENGER spacecraft will execute a 15-minute maneuver that will place it into orbit around Mercury, making it the first craft ever to do so, and initiating a one-year science campaign to understand the innermost...

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...

NASA will host a media teleconference at 1 p.m. EDT on Tuesday, March 15, to discuss the first spacecraft to orbit Mercury. NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging, or MESSENGER, will enter orbit at approximately 9 p.m. EDT on Thursday, March 17. The spacecraft has conducted more than a dozen laps through the inner solar system for the past 6.6 years. Media teleconference participants are: -- Andy Calloway, MESSENGER mission operations manager, Johns Hopkins...

After more than a dozen laps through the inner solar system, NASA's MESSENGER spacecraft will move into orbit around Mercury on March 17, 2011. The durable spacecraft--carrying seven science instruments and fortified against the blistering environs near the sun--will be the first to orbit the innermost planet. At 8:45 p.m. EDT, MESSENGER--having pointed its largest thruster very close to the direction of travel--will fire that thruster for nearly 14 minutes, with other thrusters firing for an...

Nine days from now "“ on March 17 "“ the MESSENGER spacecraft will execute a 15-minute maneuver that will place it into orbit about Mercury, making it the first craft ever to do so, and initiating a one-year science campaign to understand the innermost planet. Starting Monday, antennas from each of the three Deep Space Network (DSN) ground stations began a round-the-clock vigil, allowing flight control engineers at the Johns Hopkins University Applied Physics Laboratory (APL) in...

Part of the answer to how and why primates differ from other mammals, and humans differ from other primates, may lie in the repetitive stretches of the genome that were once considered "junk." A new study by researchers at the University of Iowa Carver College of Medicine finds that when a particular type of repetitive DNA segment, known as an Alu element, is inserted into existing genes, they can alter the rate at which proteins are produced -- a mechanism that could contribute to the...

NASA's MESSENGER probe is about set a milestone for spacecraft as it becomes the first probe to orbit Mercury. MESSENGER's team outlined details to scientists at a conference in Washington DC. The spacecraft has already made three flybys of Mercury and is set to enter orbit around the rocky world on March 17. NASA's Mariner 10 spacecraft made several passes of the planet in the 1970s and sent pictures back of what appeared to be an uninteresting planet compared with Venus, Mars and the...

What would our solar system look like if visitors from other worlds took a series of pictures? NASA's MESSENGER spacecraft did just that by piecing together the first portrait of our solar system from the inside looking out. Comprised of 34 images, the mosaic provides a complement to the solar system portrait--from the outside looking in--taken by Voyager 1 in 1990. "Obtaining this portrait was a terrific feat by the MESSENGER team," says MESSENGER principal investigator Sean Solomon, of the...

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...
