An ancient lake on Mars was capable of supporting life for tens or hundreds of thousands of years, researchers reported today based on findings from NASAs Curiosity rover. In March, NASA announced that the lake was once capable of supporting microbial life, but little more was known. There would have been some snow, maybe ice up in the mountains around the crater rim, John Grotzinger, project scientist for Curiosity, said at a press conference this morning. Not long after touching down in the Gale Crater last August, NASAs Curiosity rover was driven over to Yellowknife Bay, a trough over 16-feet deep made up of basaltic sandstones.
