NASA’s next Mars rover was not silent on the long journey to the Red Planet.
A microphone on board Tuesday 2020 Rover PerseveranceIt was launched on July 30 and will touch on February 18, 2021, capturing the sound of the car-sized robot’s “heat-repelling liquid pump”, reveals the newly released NASA audio file.
Entry into Perseverance, Descent and Landing (EDL), “Seven minutes of terror“The sequence ends with the lowering of the Mars rover onto Sky Crane cables powered by a rocket.

That sound does not travel through the void of space; Sound waves need a means to propagate. In this case, the waves passed through the diligent’s body, causing the mechanical vibrations recorded by the microphone.
I apologize to the person who came up with the slogan “Alien” and I think you can say that no one can hear you scream in space, but they can hear your liquid pump repelling the heat, “said Dave Cruel, chief engineer for Mars. ” EDL 2020 camera and microphone subsystem. Said in a statement Wednesday (November 18th).
“The larger the audio file, the more important the audio file,” Cruel added. “Landing on Mars means our system is up and running and ready to register some noise and anger.”
The heat-repelling liquid pump is part of the diligent heating system that will keep the rover and its equipment warm on Mars, which will spread the heat generated by the mission’s nuclear battery, NASA officials said in the report.
Diligence will explore the site of the Jesero Gorge, 45 kilometers wide, which in ancient times blocked a lake and a river delta. The rover represents the geography of the site and hunts for ancient signs Planet Mars And models for future return missions to Earth.
Diligence will also test technologies for future exploration of the Red Planet. For example, one of the rover’s instruments, called MOXIE (abbreviated as “Mars Oxygen ISRU Experiment”), will produce oxygen from the thin Martian atmosphere dominated by carbon dioxide. NASA officials say if such equipment is measured, it could help humanity set foot on the Red Planet.
Flying to Mars attached to the womb of perseverance is small Ingenuity of the helicopter. If all goes to plan, 4-LP. (1.8 kg) will perform some short test flights on the Intermediate Red Planet, the first aircraft to operate in alien skies.
Built by the Danish company DPA Microphones, EDL Mic isn’t the only audio diligence tool. Rover has a second microphone designed to record the sounds created by its super rock-japping game.
Self These microphones At work, they will be the first person to record real audio on Mars. (Captured NASA’s Insight lander The “sounds” of the Martian wind After its 2018 Touchdown, but the processed data record was collected by the air pressure sensor and seismometer measurement.)
But the new microphones didn’t fly first on the Red Planet mission. NASA’s Mars Polar Lander spacecraft crashed during its touchdown attempt in December 1999, sending a microphone. NASA’s Phoenix Lander, which supported its 2008 water hunting mission, integrated a microphone into its descent camera. But the Phoenix team Never run that tool, Concerned that its use will complicate the landing process.
