Levin, a maverick researcher who has often run afoul of the NASA bureaucracy, has insisted for decades that “it is more likely than not that we detected life.” Now, he and LR co-experimenter Patricia Ann Straat are calling for further investigation. Afrozen sea may still be there today, buried under a layer of volcanic dust. Well, strictly speaking, you can’t. Humans have yet to even step foot on Mars, but architects are already designing homes people can live in on the distant planet for NASA. He proposed that the LR experiment be repeated on Mars, with certain amendments, and then have its data studied by a panel of experts. Over the past nine years, scientists have taken Sagan’s words very much to heart. Get the best of Smithsonian magazine by email.

Sending humans to Mars is a phenomenal undertaking by all standards and presents very real risks and challenges. Its thin atmosphere cannot block ultraviolet radiation from space, which would devastate any known living thing on the surface of the planet. A small number of bacterial species today do the same—anoxygenic photosynthesis it’s called—and Tice and Lowe suggest that such microbes, rather than the conventionally photosynthetic ones studied by Schopf and others, flourished during the early evolution of life. Other recent claims also are under assault. To support Kurzgesagt and learn more about Brilliant, go to https://www.brilliant.org/nutshell and sign up for free. The atmosphere of Mars is mostly carbon dioxide, the surface of the planet is too cold to sustain human life, and the planet’s gravity is a mere 38% of Earth’s. It also had crystals of magnetic iron oxide, called magnetite, which some bacteria produce. It allows the … According to new findings of NASA’s Mars Reconnaissance Orbiter (MRO), there is evidence that liquid water flows on present-day Mars¹. InSight is scheduled to touch down on the Red Planet at approximately noon PST (3 p.m. EST) on Nov. 26. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to study the "inner space" of Mars: its crust, mantle, and core. However, other experiments failed to find any organic material and NASA couldn’t duplicate the results in their laboratory – so they dismissed the positive result as false positives, some unknown chemical reaction rather than proof of extraterrestrial life. Some 75 percent of the scientists said they thought life once existed there, and of them, 25 percent think that Mars harbors life today. However, the hope and ambition for this purpose are well alive and present.
