Finally NASA succeeds: Confirming life of Human Beings on Mars

NASA confirms presence of water on Mars. The much awaited result by NASA confirms the hope of life on Mars. According to the researchers Liquid Water runs down canyons and crater walls over the summer months on Mars.

The trickles leave long, dark stains on the Martian terrain that can reach hundreds of metres downhill in the warmer months, before they dry up in the autumn as surface temperatures drop.

The Lead Scientist on NASA’s Mars Exploration Programme, Michael Mayer said,” There is liquid water today on the surface of Mars, because of this, we suspect that it is at least possible to have a habitable environment today”.

But occasionally, Mars probes have found hints that the planet might still be wet. Nearly a decade ago, NASA’s Mars Global Surveyor took pictures of what appeared to be water bursting through a gully wall and flowing around boulders and other rocky debris. In 2011, the high-resolution camera on NASA’s Mars Reconnaissance Orbiter captured what looked like little streams flowing down crater walls from late spring to early autumn. Not wanting to assume too much, mission scientists named the flows “recurring slope linear” or RSL.

“These may be the best places to search for extant life near the surface of Mars,” said Alfred McEwen, a planetary geologist at the University of Arizona and senior author on the study. “While it would be very important to find evidence of ancient life, it would be difficult to understand the biology. Current life would be much more informative.”

“The mystery has been, what is permitting this flow? Presumably water, but until now, there has been no spectral signature,” Meyer said. “From this, we conclude that the RSL are generated by water interacting with perchlorates, forming a brine that flows downhill.”
