PASADENA, Calif., Dec. 11 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to...

NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to examine Mars in unprecedented detail during its next two-year phase of science operations. Among the major findings...

China and Russia have plans to send two satellite probes to Mars and one of its moons in October 2009, according to a Shanghai Space Administration official.Chen Changya, who is also deputy designer-in-chief of China's Mars rover, reported plans on Wednesday at an aerospace exhibition in Shanghai.China intends to send a small spacecraft called Yinghuo-1 into orbit by August 2010. Yinghuo-1 will collect scientific data using two cameras while in orbit. It will constantly transmit data back to...

The U.S. space agency says it is postponing the launch of its Mars Science Laboratory until 2011. National Aeronautics and Space Administration officials said the original October 2009 launch is no longer feasible because of testing and hardware challenges that must be addressed to ensure mission success. NASA said the relative positions of Earth and Mars are favorable for flights to Mars only a few weeks every two years. The next launch opportunity after 2009 is in 2011. We will not lessen...

The U.S. space agency says it has, most likely -- after a month of fruitless attempts -- reached the end of communications with its Phoenix Mars Lander. The National Aeronautics and Space Administration said it has ceased its daily attempts to communicate with the spacecraft and has stopped using its Mars orbiters to hail the lander and listen for its signals. The final communication from Phoenix remains a brief signal received via NASA's Mars Odyssey orbiter on Nov. 2, the space agency said....

As much as a third of Mars could have been underwater, UA scientists say An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. "We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface, and an inner shoreline believed...

NASA's Phoenix Mars Lander has ceased communications after operating for more than five months. As anticipated, seasonal decline in sunshine at the robot's arctic landing site is not providing enough sunlight for the solar arrays to collect the power necessary to charge batteries that operate the lander's instruments. Mission engineers last received a signal from the lander on Nov. 2. Phoenix, in addition to shorter daylight, has encountered a dustier sky, more clouds and colder temperatures...

European space scientists are getting closer to unravelling the origin of Mars' larger moon, Phobos. Thanks to a series of close encounters by ESA's Mars Express spacecraft, the moon looks almost certain to be a "Ëœrubble pile', rather than a single solid object. However, mysteries remain about where the rubble came from. Unlike Earth, with its single large moon, Mars plays host to two small moons. The larger one is Phobos, an irregularly sized lump of space rock measuring just...

By MARC KAUFMAN By Marc Kaufman The Washington Post WASHINGTON Icy snow falls from high in the Martian atmosphere and may even reach the planet's surface, scientists working with NASA's Phoenix Mars lander reported Monday. Laser instruments aboard the lander detected the snow in clouds about 2 1/2 miles above the surface and followed the precipitation as it fell more than a mile toward the ground. But because of limitations with the technology, it was unclear whether any of the...

PASADENA, Calif. "“ NASA's Mars Reconnaissance Orbiter has revealed hundreds of small fractures exposed on the Martian surface that billions of years ago directed flows of water through underground Martian sandstone. Researchers used images from the spacecraft's High Resolution Imaging Science Experiment, or HiRISE, camera. Images of layered rock deposits at equatorial Martian sites show the clusters of fractures to be a type called deformation bands, caused by stresses below the...
