NASA Curiosity rover digs Mars, finds sulfur, chlorine and organic traces of unknown@ 2012/12/04
What's Mars made of? Well, after scooping up some loose sand, Curiosity's Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instruments found a menagerie of chemicals, including sulfur, chlorine, and traces of carbon-based materials. Don't get carried away thinking there's life on Mars just yet, however, because NASA's boffins aren't sure the organic molecules are native -- they may have come from Earth on this, or a previous mission. Still, the analysis is a significant step in unlocking Mars' secrets, and the high quality data resulting from it will keep NASA's best and brightest busy as Curiosity continues sampling Martian dirt in the coming months.
