In 1976, when two NASA Viking landers came full stop on the Red Planet, the stationary spacecraft were seeking to answer a weighty question: Is there life on Mars?
Gilbert Levin was the principal investigator of the Viking Labeled Release (LR) life detection experiment. The instrument at both landing locales got positive responses.
However, a consensus of scientists did not agree his results were proof of life. In 1997 Levin concluded that the experiment had, indeed, detected life on Mars – and he’s championed that belief ever since.
Take a look at my new story up today on Space.com regarding this ongoing discussion about life detection on Mars – decades ago!
