NASA has refuted the statement of a former researcher of his, Gilbert Levinque, who said last week that the space agency "found evidence of life" on Mars during the unmanned Viking missions (1975-80), one of whose experiments was directed for him, Fox News reports.
"The vast majority of the scientific community does not believe that the results of the Viking mission experiments alone reach the level of extraordinary evidence," said NASA spokesman Allard Beutel in an email to Fox News.
According to Beutel, one of the agency's main objectives remains the search for life in the universe. "Although we still have to find signs of extraterrestrial life, NASA is exploring the Solar System and beyond to help us answer fundamental questions, including whether we are alone in the universe," the spokesman added.RELATED
In addition, he stressed that for this purpose the space agency directs scientific missions to Mars, Enceladus (Saturn satellite) and Europe (Jupiter satellite) and seeks bio-signatures in the atmosphere of planets outside the solar system.
"We found evidence of life on Mars"
Gilbert Levin, once a scientist at the service of NASA, published on October 10 a text entitled 'I am convinced that we found evidence of life on Mars in the 70s', in which he maintains that the Viking Lander mission detected the First concrete test of biological life outside our planet.
That space mission, in which Levin participated, took samples of Martian soil, and the results, he explains, seemed to indicate that carbon dioxide was "being regenerated, possibly by microorganisms such as on Earth." However, unable to detect signs of organic matter, the experiment concluded that he had found a substance that "mimicked life, but is not life."
The expert regrets that in the 43 years since this mission, "none of the subsequent modules of NASA has brought to Mars a life detection instrument, to give continuity to these exciting results."
