By Warren E. Leary Pictures of Martian gullies taken several years apart strongly suggest that water still flows at least occasionally on the surface of the planet, scientists have announced.
NASA sees hint of liquid water on Mars WASHINGTON, Dec. 6 (Xinhua) -- Images sent back by NASA's Mars Global Surveyor orbiter suggest the existence of liquid water on Mars which heightens the potential for microbial life on the Red Planet, NASA scientists said on Wednesday.
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.
Liquid water has flowed on the surface of Mars within the past few years, leaving behind new deposits in gullies monitored by the now-lost Mars Global Surveyor. The results seem to boost the chances that Mars could harbour life.
During its first week of observations from low orbit, NASA's newest Mars spacecraft is already revealing new clues about both recent and ancient environments on the red planet.
The climate on Mars is showing a warming trend and recent images have shown the first evidence of seismic activity on Earth's neighbor planet, scientists said on Tuesday.
New gullies that did not exist in mid-2002 have appeared on a Martian sand dune. Boulders tumbling down a Martian slope left tracks that weren't there two years ago. Those are just two of the surprising discoveries that have resulted from the extended life of NASA's Mars Global Surveyor, which this month began its ninth year in orbit around Mars.
NASA's Mars Reconnaissance Orbiter, launched on Aug. 12, has completed one of the first tasks of its seven-month cruise to Mars, a calibration activity for the spacecraft's Mars Color Imager instrument.
NASA has selected eight proposals to provide instrumentation and associated science investigations for the mobile Mars Science Laboratory rover, scheduled for launch in 2009. Proposals selected today were submitted to NASA in response to an announcement of opportunity released in April.
