Tucson (UPI) Aug 27, 2010 A NASA spacecraft with a high-resolution camera has photographed a young Mars crater and found frozen water in it, scientists say. A recent image from NASA's Mars Reconnaissance Orbiter HiRISE camera shows water ice at the bottom of a 20-foot-wide crater on the planet's surface, SPACE.com reported Friday. Researchers suspect the crater in the northern hemisphere formed recently, no earlier than April 2004, Nathan Bridges, a HiRISE science team member at the University of Arizona, said. The crater appeared in photos taken between June 6 and July 7. "It's showing we're getting ice pretty far south," Bridges said. "As we continue to look at these things it's a good way to determine where shallow ice is on Mars." The ice patch covers an area of up to 20 square feet. It "is probably at the same depth and has a similar origin to that excavated by the Phoenix lander back in 2008," he said. NASA's Phoenix Mars Lander landed in the Martian arctic in May 2008 and found evidence of water ice just beneath the surface. During the next Martian summer "the HiRISE team will likely take additional pictures to check up on the crater," Bridges said.

Wet Era On Early Mars Was GlobalParis, France (SPX) Jun 28, 2010 Conditions favourable to life may once have existed all over Mars. Detailed studies of minerals found inside craters show that liquid water was widespread, not only in the southern highlands, but also beneath the northern plains. ESA's Mars Express and NASA's Mars Reconnaissance Orbiter have discovered hydrated silicate minerals in the northern lowlands of Mars, a clear indication that wat ... read more |
