Initial asteroid attacks on Mars could have made "vital ingredients for life"

Scientists have searched the universe for a long time, but a recent study suggests that ancient asteroid influences have produced "important components of life" right next door ̵

1; Mars. 19659004] A new study published in the Journal of Geophysical Research: Planets: Planets suggests that if Mars had a hydrogen-rich atmosphere, the space rocks might have delivered solid forms of nitrogen known as nitrites and nitrates. In 2015, NASA's Curiosity Rover found nitrate on the Gale Crater, and before the study, the researchers were not sure where they came from.

Researchers were able to mimic the early Martian atmosphere by blending mixtures of varying levels of hydrogen and nitrogen and bottled carbon dioxide, which were then hit with infrared laser pulses to determine the amount of nitrate formed. A great surprise was that nitrate yields increased , as hydrogen was included in the laser-shocked experiments simulating asteroid impacts, "the study's lead author, Dr. Rafael Navarro-González, said in a statement.

Navarro-González continued," This was not intuitive, Hydrogen leads to an oxygen-deficient environment, whereas the formation of nitrate requires oxygen, but the presence of hydrogen resulted in a faster cooling of the shock-heated gas, capturing nitrate, the precursor of nitrate, at higher temperatures with higher yields. "[19659004] As Space.com notes, this is The Martian atmosphere is only 1 percent as thick as Earth, but four billion years ago it was much thicker. The ancient planet once had vast lakes and seas, but due to the weakened atmosphere, they have largely evaporated.

The prospect of significant amounts of hydrogen in the ancient Martian atmosphere could mean that the planet once supported life.

"Hydrogen as a greenhouse gas in the atmosphere is interesting for both the climate history of Mars and for habitability," said co-author Jennifer Stern, a planetary geochemist at NASA's Goddard Space Flight Center in Greenbelt, MD

LIFE ON THE EARTH CAN COME FROM COLLISION WITH THE OLD PLANET MORE THAN 4 BILLION YEARS AGO with liquid surface water and an increased production of nitrates, which are vital – it is very exciting, "she continued. "The results of this study suggest that these two things that are important to life fit together, and one reinforces the other's presence."

A study at the end of 2018 suggested that a life could hide beneath the surface of Mars Salty, Underground Lakes.
