Ex-NASA Scientist Says Life Was Discovered on Mars in the 1970s

Now, a former NASA scientist, Gilbert V. Levin, is claiming that the space programme had confirmation of life on Mars nearly 40 years ago. "In keeping with well-established scientific protocol, I believe an effort should be made to put life detection experiments on the next Mars mission possible", Levin writes in his article.

Unfortunately, NASA discarded the results of the LR experiment because the Viking Molecular Analysis Experiment failed to detect organic matter.

It was the same objective that NASA's Viking program in the '70s had, and it involved several experiments, including the Labeled Release (LR) led by engineer and principal investigator Gilbert Levin.

Levin recounts how "amazingly" the initial results of the experiment were positive for microorganisms - and corroborated by both separate Mars landers some 4,000 miles apart.

In the op-ed, Levin criticized the space agency for not following up on the LR findings, even if NASA concluded that it "found a substance mimicking life, but not life".

Other experiments yielded different results, though, so they dismissed the positive result as a false positive. The data curves signalled the detection of microbial respiration on the Red Planet. And, he argued, Nasa must do more to follow them up - because they could pose a significant threat to life on Earth.

Much to Levin's dismay, NASA's 2020 lander mission will not be including a life-detection test.

NASA goal has continued to drag its fee t, in Levin's eyes.

Any life there might threaten them, and us upon their return. "Thus, the issue of life on Mars is now front and center".

In the experiment, the Viking probes placed nutrients in Mars soil samples - if life were present, it would consume the food and leave gaseous traces of its metabolism, which radioactive monitors would then detect.

While it's true that the results aren't necessarily a "smoking gun" in the search for life, part of Levin's argument remains valid. But perhaps most strongly of all, he said there had been no experiment that had provided an alternative explanation for the results that came back from the LV experiment.

Before now a couple of years, there's been a slew of evidence to assist the concept of Mars, at some point up to now, had massive bodies of water and an atmosphere. "Furthermore, laboratory studies have shown that some terrestrial microorganisms could survive and grow on Mars".

However, we are once again seeing promising signs of life on Mars thanks to the work of NASA's Curiosity rover.
