For the people that are looking for life on Mars, the red planet , we know that there are good times and bad times. Nearly 35 years after NASA’s twin Viking robots landed onto its ruddy surface, there is no
evidence that living organisms ever existed on the fourth planet from the sun.sun. Few researchers accept that the 1976 Viking experiment detected life. The brief frenzy over possible fossils in a Mars meteorite has fizzled.
“In recent years the case has been made again and again that life is or was possible there.” Undergirding this new optimism are reams of data—from Earth-based telescopes as well as Mars orbiters, landers, and rovers—that have slowly painted a much more complete and complicated picture of the Mars environment stretching back billions of years, providing intriguing hints that microbes might have once evolved there, and might yet endure said Bruce Jackosky.
