The @NASA astrobiology community mourns the loss of Dr. Gil Levin. He passed away on July 26, 2021 at the age of 97. Dr. Levin was part of NASA’s 1976 Viking mission to Mars, and led the Viking Labeled Release life detection experiment.
Very sad to learn that Gil Levin has died. He was one of the original researchers on the Viking mission & the first successful landers on Mars. He insisted that Viking *had* found life there. Right or wrong, he challenged us and moved science forward.
