Former NASA scientist: We found life on Mars in the 1970s”

Levin, a principal investigator on a NASA experiment that sent Viking landers to Mars in 1976, said that the experiment's positive results were proof that life on the red planet existed. It seemed we had answered that ultimate question.

Levin actually criticized the space agency for not taking into account the RL findings, even if the company said that they found a substance that's mimicking life, but it's not actually life. It mentioned, "The Labeled Release experiment on the Viking mission reported positive results, although most have dismissed them as inorganic chemical reactions". He argues that in NASA's long history of exploring Mars, it has failed - since the 1976 missions - to search for direct evidence of life, despite the search being "among its highest priorities".

The experiment called the Labeled Release (LR) placed nutrients in Mars soil samples, assuming that if life were present, it would consume the food and leave carbon dioxide traces.

NASA scientists recently described how they found an ancient oasis on Mars which was an important discovery for evaluating habitability on Mars.

The upcoming mission of NASA's rover will, however, be searching for past evidence of life on Mars. "The astonishing fact is that there is none", he wrote.

The Mars Curiosity Rover has recovered new panorama pictures on Vera Rubin Ridge. "From studying water on Mars, probing promising 'oceans worlds, ' such as Enceladus and Europa, to looking for biosignatures in the atmospheres of planets outside our solar system, NASA's science missions are working together with a goal to find unmistakable signs of life beyond Earth". Now, he and LR co-test Patricia Ann Straat are calling for further investigation. Scientists have taken a look before and, generally speaking, there's no consensus that those particular experiments indicate that there is, or ever has been, life on Mars.

He proposed that the LR experiment be repeated on March, with certain amendments, and then have its data studied by a panel of experts. He claims: "Such an objective jury might conclude, as I did, that the Viking LR did find life". It has a instrument for the search of previous indicators of life on Mars-the Scanning Liveable Environments with the Raman & Luminescence instrument, SHERLOC.

In a Scientific American article published today, Levin explains how two separate craft landed on the surface of the red planet and conducted a series of tests to determine if there were was life. The former NASA scientist also argued that lab tests confirmed microorganisms have the potential to survive the Martian environment.
