Messenger Team Releases First Global Map of Mercury Washington DC (SPX) Dec 18, 2009 
NASA's Messenger mission team and cartographic experts from the U. S. Geological Survey have created a critical tool for planning the first orbital observations of the planet Mercury - a global mosaic of the planet that will help scientists pinpoint craters, faults, and other features for observation. The map was created from images taken during the Messenger spacecraft's three flybys of ... read moreDeep-Space Maneuver Positions MESSENGER For Mercury Orbit Insertion 
Laurel MD (SPX) Nov 27, 2009The Mercury-bound MESSENGER spacecraft completed its fifth and final deep-space maneuver of the mission today, providing the expected velocity change needed to place the spacecraft on course to enter into orbit about Mercury in March 2011. A 3.3-minute firing of its bi-propellant engine provided nearly all of the probe's 177 meter per second (396 mile per hour) increase in its speed ... more

Mercury probe fly-by maps mysterious inner planet
Washington (AFP) Nov 6, 2009The US space probe Messenger's third and final fly-by of the planet Mercury in September revealed an almost complete view of the solar system's smallest planet, leaving only the polar regions to be surveyed, NASA said. Flying at a low altitude, the Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging) probe's cameras have now mapped some 98 percent of Mercury's surface ... more Hidden Territory On Mercury Revealed 
Huntsville AL (SPX) Nov 04, 2009The MESSENGER spacecraft's third flyby of the planet Mercury has given scientists, for the first time, an almost complete view of the planet's surface and revealed some dramatic changes in Mercury's comet-like tail. "The new images remind us that Mercury continues to hold surprises," says Sean Solomon, principal investigator for the mission and director of the Department of Terrestrial ... more Mercury Rising 
MOffett Field CA (SPX) Nov 05, 2009A NASA spacecraft's third and final flyby of Mercury gives scientists, for the first time, an almost complete view of the planet's surface and provides new scientific findings about this relatively unknown world. The Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, known as MESSENGER, flew by Mercury on Sept. 29. The probe completed a critical gravity assist to ... more MESSENGER Gains Critical Gravity Assist For Mercury Orbital Observations 
Baltimore MD (SPX) Oct 02, 2009MESSENGER successfully flew by Mercury yesterday, gaining a critical gravity assist that will enable it to enter orbit about Mercury in 2011 and capturing images of five percent of the planet never before seen. With more than 90 percent of the planet's surface already imaged, MESSENGER's science team had drafted an ambitious observation campaign designed to tease out additional details ... more |

Magnetic Tornadoes Could Liberate Mercury's Tenuous Atmosphere
Greenebelt MD (SPX) Jun 04, 2009As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). It is also the smallest rocky planet, so its gravity is weak, only about 38 percent of Earth's. These conditions make it hard for the planet to hold on to its atmosphere, which is extremely thin, and invisible to the human eye. Howev ... more Magnesium Detected During Second Flyby Of Mercury
Baltimore MD (SPX) May 05, 2009NASA's MESSENGER spacecraft served up another curveball to a University of Colorado at Boulder team after a second flyby of the hot inner planet Oct. 6 detected magnesium - an element created inside exploding stars and which is found in many medicine cabinets on Earth - clumped in the tenuous atmosphere of the planet. Scientists had suspected magnesium would be present, but were surprised ... more An Active Mercury 
Huntsville AL (SPX) May 01, 2009A NASA spacecraft gliding over the surface of Mercury has revealed that the planet's atmosphere, magnetosphere, and its geological past display greater levels of activity than scientists first suspected. The probe also discovered a large impact basin named "Rembrandt" measuring about 430 miles in diameter - equal to the distance between Washington and Boston. These new findings and more ar ... more Mercury flyby unveiled active inner planet: studies
Washington (AFP) April 30, 2009The US space probe MESSENGER's second fly-by of the planet Mercury in October 2008 revealed the solar system's smallest planet to be far more active than previously thought, four studies said Thursday. The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging) probe's cameras took more than 1,200 images of the surface, including details of a mammoth well-preserved 692-kilom ... more |
