NASA’s Mars Perseverance rover beams again first sounds ever recorded on one other planet


NASA’s Perseverance rover, which landed on Mars lower than one week in the past, has beamed again the first-ever audio recordings from the floor of the purple planet. 

NASA launched the audio clips Monday, together with never-before-seen video footage of the rover touchdown final Thursday, and essentially the most subtle photos but taken of Mars. 

Along with 25 onboard cameras, the rover additionally carries two microphones. One didn’t work through the rover’s descent, however the different captured the sounds of the Martian wind blowing previous, in addition to the whirring noise of the rover itself.

The audio snippet marks the primary sound ever recorded on one other planet. 

“For those who wonder how you land on Mars – or why it is so difficult – or how cool it would be to do so – you need look no further,” mentioned performing NASA Administrator Steve Jurczyk. 

In the primary recording, sounds from the rover itself are extra distinguished. In the second, NASA filtered the audio to make sounds from Mars clearer. 

“Imagine yourself sitting on the surface of Mars and listening to the surroundings,” Dave Gruel, lead engineer for the rover’s digicam and microphone subsystem, mentioned throughout a information briefing. “It’s cool. Really neat. Overwhelming, if you will.”

Gruel mentioned that he was significantly excited for the audio recordings in order that people who find themselves visually impaired can nonetheless really feel the identical pleasure of reaching Mars as those that can view photos and movies.  

Mission crew members mentioned Monday that they hope to listen to many extra sounds from Mars, together with wind, storms, falling rocks and the sound of Perseverance’s wheels because it strikes or its drill because it digs into the Martian floor. 

Audio may sign to scientists how effectively Perseverance is functioning, and doubtlessly establish points with the rover. But, attributable to Mars’ harsh circumstances, scientists warn that the microphones could not final the period of the mission. 

Thomas Zurbuchen, affiliate administrator for NASA’s Science Mission Directorate, mentioned the recordings are “the closest you can get to landing on Mars without putting on a pressure suit.”

Scientists have tried to listen to Mars earlier than. Microphones have traveled to the purple planet twice — the Mars Polar Lander failed, and the microphone aboard the Phoenix Lander was by no means turned on. 

In 2018, NASA’s Insight Mars lander unexpectedly picked up comparable sounds of Martian wind vibrations utilizing its air strain sensor and seismometer. But, Perseverance has captured the actual factor from Mars’ floor, utilizing “commercial off-the-shelf” microphones, particularly devoted to selecting up audio. 

Perseverance will quickly get to work trying to find indicators of historic life within the Jezero Crater. And a decade from now, it plans to be the primary to ship samples from the purple planet again to Earth.
