NASA scientist explains why no life has been found on Mars

Scientists have been looking for life beyond the Earth for many years, but so far their efforts have been unsuccessful. Attempts to detect living organisms on Mars have also proved fruitless. And although NASA is not going to give up and continue the search, the agency's astrobiologist Heather Graham told why so far they have not been able to find anything.

In a short video on the NASA channel, she explained that life on Mars could very well have existed in the past, but the current state of the planet leaves little chance for any living organisms. However, when they talk about the impossibility of life on Mars, they really mean life on surfaces Mars. There will be much more chances if you dig deeper than now and the researchers are busy.

The inner layers of the planet are better protected from radiation, which penetrates the thin atmosphere of the Red Planet, and there repeatedly discovered groundwater signs. To check this, we need to wait for the return of samples from Mars to Earth and their study. Now the Perseverance rover is helping to get new data, and in the future NASA

going send a manned mission that can provide more definitive answers.

Although now we cannot speak with certainty about the existence of life on Mars at least at some stage in the development of the planet, particles of organic carbon in the Gale crater, discovered rover Curiosity indirectly confirm this.
