The first NASA recording on Mars reveals life?

NASA's Perseverance rover has recorded realistic sounds lasting 5 hours on the surface of Mars.

On October 18, NASA's Jet Propulsion Laboratory released the first recordings recorded on Mars . These are also the first sounds that humans have heard from the Red Planet through a specialized microphone, mounted on a self-propelled robot called Perseverance.

Humans are moving forward step by step in their efforts to uncover the mystery of the Red Planet.

Despite being an indistinct mix of wind, rustling, and even the sound of Perseverance's engines in motion, the scientists claim this is a priceless achievement.

Specifically in research projects on the Red Planet, the resulting sounds will bring significant value, NASA confirmed. It helps them learn more about the planet's atmosphere, how sound travels through the air, as well as possibly revealing signs of life, if any.

"We've all seen beautiful images taken from Mars, but only now have the first sounds , " said Dr Lanza, a scientist at Los Alamos National Laboratory (LANL) in New Mexico, said.

"It makes me feel like I'm almost standing on the surface of Mars. It's a wonderful thing."

Unfortunately, so far, there has not been any signal, either visual or audible, that shows any sign of a species existing on the Red Planet.

It is known that the Perseverance robot is equipped with two specialized microphones, provided by LANL and a consortium of French research laboratories under the auspices of the Center National d'Etudes Spatiales (CNES).

The microphone's position - one high, and one low, helps it track total "micro-turbulence" or minute changes in the air.

The scientists even took into account atmospheric pressure, density and chemistry to simulate how sounds from Earth might change on Mars.

Previously, they believed that because the atmosphere on Mars is thinner than on Earth, it would be difficult to detect high-pitched sounds.

However, based on the recordings, scientists were surprised when specialized microphones were able to capture clear sound from the rotors of the extremely small Ingenuity helicopter robot, operating about a distance away. 80m on April 30.

From there, they were able to eliminate 2 out of 3 predictive models of how sound is traveling on Mars.

According to NASA, understanding the nature of sounds on Mars could help scientists diagnose problems with a spacecraft when it lands on a distant planet. From there they will plan to better prepare for future visits to the Red Planet.
