NASA: New evidence of water on
Mars
BEIJING,
Dec. 7 (Xinhuanet) -- NASA scientists searching for clues of "ancient water" on
Mars now feel they have photographic evidence of recent water flow in some of
the gullies that lace the planet's surface.
The changing appearance of gullies on Mars over the
last seven years suggests that liquid water flowed recently on the Red Planet
and may still seep out in brief bursts, researchers said Wednesday.
New images of known gullies on Mars show evidence of
new flows and deposits, pointing to explosive events in which some form of water
burst from crater walls and ran down their slopes and support what researchers
call "the squirting gun" theory.
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.
NASA scientists made the judgement based on images
taken in 2004 and 2005 revealing 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. [1] [2] [3] [4] [5] [6] [7]
