Mars rover finds conditions 'more conducive to life'

More than four years after they were gathered, hard-to-interpret data from the Mars rover Spirit have finally been cracked. They reveal carbonate minerals to be a major component of a rock formation known as Comanche in the Columbia Hills region of the Gusev Crater.

"The discovery is significant," says Oded Aharonson, a planetary scientist at the California Institute of Technology in Pasadena who was not directly involved in the find, "because of the intimate connection between the formation of carbonates and persistent liquid water." That connection helps to solidify the view that Mars was once warm, wet and perhaps capable of supporting life.

A geologic mapping project using NASA spacecraft data offers new evidence that expansive lakes did exist long ago on Mars.

A series of sedimentary deposits indicates the presence of large standing bodies of water in Hellas Planitia located in the southern hemisphere of Mars, said by Dr. Leslie Bleamaster, research scientist at the Planetary Science Institute.

These deposits resulted from erosion and transport of highland rim materials into a basin-wide standing body of water, Bleamaster said.

Hellas basin, more than 2,000 km across and 8 km deep, is the largest recognized impact structure on the Martian surface, according to him.
