Although noffke makes a tantalizing case for possible signs of ancient life on mars, her report is not a definitive proof that these structures were shaped by biology getting such confirmation would involve returning rock samples to earth and conducting additional microscopic analyses, a mission that isn’t scheduled anytime in the near future. At a site selected for better preservation of ancient materials, we just may be able to determine whether these molecules came from space, from igneous rocks, from hydrothermal activity, or -- the most exciting possibility -- ancient mars life.
The evidence (via nbc news) has been found by nasa's curiosity rover, a robotic vehicle that has been conducting experiments and exploring mars for almost six years now curiosity recently discovered carbon-containing compounds in an ancient lakebed, as well as shifting levels of the organic molecule methane in the martian atmosphere.
If we found life on mars, how would we know if one is faced with tantalizing evidence of a possible 'find' of ancient life on mars, rummel said, one's first consideration would be to. Mars sample return mission — the best life detection experiment proposed is the examination on earth of a soil sample from mars however, the difficulty of providing and maintaining life support over the months of transit from mars to earth remains to be solved.
In a new 'field guide' for discovering fossils on mars, researchers say iron-rich rocks located near the sites of ancient lakes should be the priority for upcoming visits to the martian surface, because they are acting like mineral sanctuaries that could preserve signs of life from billions of years ago.
The quest for signs of ancient life on mars received a major boost today after nasa revealed that its curiosity rover has found signs of organic molecules that date back at least three billion. While we know that mars was habitable in the past, the case demonstrates just how hard it will be to ever prove the existence of past life on its surface but now new results from nasa’s curiosity rover, including the discovery of ancient organic material, have revived the hope of doing just that.
The mariner spacecraft destroyed lowell’s vision of intelligent martians when they sent back images of an arid, ancient mars, without any sign of life or its works however, scientists still thought that mars was the most likely place to find life in the solar system.
