Life on Mars? NASA finds a living atmosphere; | Science | News


A new study has revealed that asteroid effects on ancient Mars could have produced ingredients for life if Mars's atmosphere was full of hydrogen. Researchers on a Curiosity Sample Analysis in Mars (SAM) said that an atmosphere full of hydrogen would explain how the planet lived. The ingredients are nitrite (NO2) and nitrates (NO3).

The two nitrates are important to establish and maintain life.

The roamer found both ingredients in soil and rock samples in the Gale Crater, the site of ancient lakes on Mars.

Researchers recreated the early atmosphere of the planet in Merthyr to understand how fixed nitrogen could have been deposited in the crater.

They found that the Planet Goch had been warmer in the past.

Dr Rafael Navarro-González said: “The great surprise was that the nitrate product had increased when hydrogen was included in the laser experiments which simulated the effects of asteroid.

“This was insubstantial as hydrogen resulted in an oxygen deficiency environment while oxygen was needed to form nitrate.

“However, the presence of hydrogen led to the faster cooling of the shock gas, nitric oxide capture, nitrate precursor, at a high temperature where its output was higher.

Climate models show that hydrogen in the atmosphere is necessary to raise temperatures to get fluid on the surface of the planet.

Christopher McKay explained that the presence of nitrate is of “a major astrological significance.”

He said: "Due to the low levels of nitrogen gas in the atmosphere, nitrate is the only type of nitrogen that is biologically useful on Mars.

“So its presence in the soil is of great astrological significance.

“This paper helps us to understand the possible sources of that nitrate.” T
