Three days ago we have informed you about NASA Curiosity rover, that it had some news for us. The rover has been analyzed drilled samples on Mars in their labs more than a year. We have mentioned that the discoveries are going to be unveiled on Thursday, June 7. So, according to NASA the Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life. It was also found the new evidence in the Martian atmosphere relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface.
Curiosity rover has identified a variety of organic molecules, the carbon-based building blocks of life.
“The new findings – “tough” organic molecules in three-billion-year-old sedimentary rocks near the surface, as well as seasonal variations in the levels of methane in the atmosphere – appear in the June 8 edition of the journal Science” writes NASA.
“With these new findings, Mars is telling us to stay the course and keep searching for evidence of life,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters, in Washington. “I’m confident that our ongoing and planned missions will unlock even more breathtaking discoveries on the Red Planet.”
As the word of Eigenbrode, who is lead author of one of the two new Science papers, the Martian surface was exposed to radiation from space. Both radiation and harsh chemicals break down organic matter. And added that to find ancient organic molecules in the top five centimeters of rock, it gives them to learn the story of organic molecules on Mars with future missions that will drill deeper.
“Curiosity has not determined the source of the organic molecules,” “whether it holds a record of ancient life, was food for life, or has existed in the absence of life, organic matter in Martian materials holds chemical clues to planetary conditions and processes.”
