NASA’s Perseverance rover may have found traces of microscopic life once existing on the surface of Mars.
NASA’s Perseverance vehicle continues to examine rock and soil samples on the surface of the red planet Mars. A piece of rock that the vehicle has just completed examining will one day end up in the history books. “First evidence of extraterrestrial life” It has the potential to pass as .
Actually NASA’s His statement does not mean that extraterrestrial life has been definitively discovered. It means a stone sample has been discovered with properties that may result from ancient microbial activity, the agency announced on Thursday. Scientists state that the stone must be brought to our planet and examined before saying anything definitive.
It has three critical features
Cheyava Falls The rock called has three critical features. Of these features first, the presence of white veins in the rock resulting from calcium sulfate. These veins are evidence that water once passed through this rock. Secondly The rock tested positive for organic compounds, which come from carbon-based building blocks as we know them. Third as small particles on the rock associated with chemical reactions. “leopard spots” is available. This points to microbial life.
However, both organic material and leopard spots from non-biological processes may have been caused by That’s why scientists need to bring the sample back to Earth to examine it more closely. Because the Perseverance vehicle has learned everything it can using the hardware on it.
