USA- The Viking probe, launched in 1976 by NASA to inspect Mars in search of biological findings, was successful, although scientists hypothesized that organic remains would have reached Mars due to the impact of meteorites on its surface. The mission found these remains that were removed by using a probe torch to extract material for investigation.

It was on a historic NASA mission in 1976, according to a recent study. A month ago, the most complex organic matter found on the red planet was found.
NASA detected in early June the most complex organic matter that has been found on the surface of Mars, an advance in the study of possible traces of life on the red planet.
The Curiosity vehicle also found evidence of seasonal variations in methane emissions, indicating that the source of this gas - which is often a signal of biological activity - comes from the planet and could be stored on ice sheets below the surface.
A little more than a month later, a study recently published in the journal "Journal of Geophysical Research: Planets" argues that another historic NASA mission, the Viking probes, could have made the same discovery more than 40 years ago, but its The results were accidentally burned by NASA, according to ABC of Spain
"In 1976, in fact, the two twin Viking lander modules carried out the first field experiments to search for organic matter on the neighboring planet." Back then, scientists were well aware that planets constantly receive rain. of micrometeorites rich in carbon and, often, more complex organic molecules, so they were convinced that Mars should be full of such substances, but the Vikings found nothing, leaving the scientists stupefied and with a span of noses ", says the text.
