SAN FRANCISCO -- Layers on Mars are yielding history lessons revealed by instruments flying overhead and rolling across the surface. Some of the first radar and imaging results from NASA's newest Mars spacecraft, the Mars Reconnaissance Orbiter, show details in layers of ice-rich deposits near the poles. Observed variations in the layers' thickness and composition will yield information about recent climate cycles on the red planet. NASA's Mars Exploration Rover Opportunity has photographed...

WASHINGTON, Dec. 6 /PRNewswire/ -- NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years. "These observations give the strongest evidence to date that water still flows occasionally on the surface of Mars," said Michael Meyer, lead scientist for NASA's Mars Exploration Program, Washington. Liquid water, as opposed to the water ice and water vapor known to exist at Mars, is...

NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years. "These observations give the strongest evidence to date that water still flows occasionally on the surface of Mars," said Michael Meyer, lead scientist for NASA's Mars Exploration Program, Washington. Liquid water, as opposed to the water ice and water vapor known to exist at Mars, is considered necessary for life. The new...

New images from NASA's Mars Reconnaissance Orbiter show three additional NASA spacecraft that have landed on Mars: the Spirit rover active on the surface since January 2004 and the two Viking landers that successfully reached the surface in 1976. The orbiter's high-resolution camera took a dramatic photograph of Spirit's twin rover, Opportunity, at the edge of a Martian crater two months ago. Besides providing new portraits of these robotic emissaries, the images provide scientists valuable...

The University of Arizona-based team that operates the high-resolution camera on NASA's Mars Reconnaissance Orbiter, in conjunction with NASA, is releasing the first of what will be a non-stop flood of incredibly detailed Mars images taken during the spacecraft's two-year primary science mission. The High Resolution Science Imaging Experiment (HiRISE) camera took almost 100 images during the first two weeks of its main science mission, which began Nov. 7. "There's no Earth analog for some...

Pasadena, Calif. -- NASA's Mars Global Surveyor has likely finished its operating career. The spacecraft has served the longest and been the most productive of any mission ever sent to the red planet. "Mars Global Surveyor has surpassed all expectations," said Michael Meyer, NASA's lead scientist for Mars exploration at NASA Headquarters, Washington. "It has already been the most productive science mission to Mars, and it will yield more discoveries as the treasury of observations it has...

An orbiting NASA spacecraft just starting to study Mars with six science instruments has successfully tested another key part of its payload, a versatile radio for relaying communications with robots on the surface of Mars. During its first relay test since reaching Mars in March, the Mars Reconnaissance Orbiter used this radio payload, called Electra, in a two-way link with NASA's Mars Exploration Rover Spirit. The orbiter has dual roles as a science mission and a telecommunications...

By ROBERT JABLON, Associated Press Writer LOS ANGELES - NASA's Mars Global Surveyor has been out of contact with Earth for nearly a week and engineers tried Friday to re-establish communication with the craft, which may be showing its age after 10 years in space. The space agency's Jet Propulsion Laboratory in Pasadena lost contact with the probe for two days last week, then received a weak carrier signal with no data on Sunday. Since then, Surveyor has not confirmed receiving a command to...

Engineers are striving to restore full communications with NASA's Mars Global Surveyor on the 10th anniversary of the spacecraft's Nov. 7, 1996, launch. The orbiter is the oldest of five NASA spacecraft currently active at the red planet. Its original mission was to examine Mars for a full Martian year, roughly two Earth years. Once that period elapsed, considering the string of discoveries, NASA extended the mission repeatedly, most recently on Oct. 1 of this year. The orbiter has operated...

Every day for the past decade, the U.S. has had a presence at Mars, using spacecraft to understand this extreme world and its potential as a past or present habitat for life. During that time, all spacecraft have become virtually incommunicado for about two weeks every two years. The reason is solar conjunction, which occurs again from October 18-29, 2006. Solar conjunction is the period when Earth and Mars, in their eternal march around the Sun, are obscured from each other by the fiery orb...
