NASA is finally receiving data on Martian soil samples from Curiosity, its rover currently traversing the red planet. The results from the soil samples hint at something exciting, but rover scientists are making very sure not to raise expectations. <\/p>\n
NASA had always planned to present early results from the mission this week at a press conference. But expectations for the press conference soared after one of the instruments onboard the rover appeared to detect organic molecules. <\/p>\n
Having already found signs of water on Mars, finding signs of organic material would be another piece of evidence that there might might, might have once been life on Mars. <\/p>\n
Paul Mahaffy, the lead scientist on Curiosity's main analysis instrument, known as the Sample Analysis at Mars, or SAM, device, says no news yet. <\/p>\n
\"SAM has no definitive detection to report of organic compounds with these first set of experiments,\" he told a meeting of the American Geophysical Union in San Francisco on Monday. <\/p>\n
Mahaffy says SAM definitely saw simple organic compounds compounds made of carbon when it analyzed its first soil sample last month. It also saw compounds made with chlorine. <\/p>\n
\"The reason we're saying we have no definitive detection of Martian organics,\" Mahaffy says, \"is that we have to be very careful to make sure both the carbon and the chlorine are coming from Mars.\" <\/p>\n
