Curiosity Finds Simple Organics, But Big Questions

Remain

 

 

 

 ” The Curiosity rover has detected organic compounds on Mars, NASA scientists announced at a press conference today. But the source of these carbon-containing molecules, which are essential to sustaining life, is still up in the air. Using Curiosity’s Sample Analysis at Mars (SAM) suite of instruments, researchers found traces of water, sulfur, and small amounts of organics in the form chlorine-containing compounds, though the researchers were quick to point out that they’re still trying to determine the source of the organics—they could very well could be from residual earth contaminants, the scientists warned. “[SAM] has made this detection of simple, organic compounds; we just don’t know if they’re indigenous to Mars or not,” said project scientist John Grotzinger. “

Speculation Centers on Organic Molecules

 

 ” Much of the internet isbuzzing over upcoming “big news” from NASA’s Curiosity rover, but the space agency’s scientists are keeping quiet about the details.

The report comes by way of the rover’s principal investigator, geologist John Grotzinger of Caltech, who said that Curiosity has uncovered exciting new results from a sample of Martian soil recently scooped up and placed in the Sample Analysis at Mars (SAM) instrument.

“This data is gonna be one for the history books. It’s looking really good,” Grotzinger told NPR in an segment published Nov. 20. Curiosity’s SAM instrument contains a vast array of tools that can vaporize soil and rocks to analyze them and measure the abundances of certain light elements such as carbon, oxygen, and nitrogen – chemicals typically associated with life. “
