NASAThis record, which landed on Mars less than a week ago, has already sent a sound recording from the surface of the red planet.
NASA released an audio clip on Monday, as well as an unprecedented audio clipOf the Wanderer Last Thursday, and the most beautiful image of Mars ever taken.
In addition to the 25 on-board cameras, the rover also has two microphones. One person did not work during the descent of the rover, but the other caught the sound of the Martian wind and the howling sound of the rover itself.
The audio clip marks the first sound recorded on another planet.
“For those of you who want to know how to land on Mars, why it̵
In the first record, the sound from the rover itself is more prominent. In the second time, NASA filtered the audio to make the sound from Mars clearer.
“Imagine sitting on the surface of Mars and listening to the surrounding environment,” said Dave Gruul, the chief engineer of the rover’s camera and microphone subsystem, at a press conference. “It’s so cool. It’s really neat. If you can, it’s overwhelming.”
Gruul said he was particularly excited about the recording, so that people with visual impairments can still reach Mars as excited as people watching images and videos.
The mission team members said on Monday that they would like to hear more sounds from Mars, including wind, storms, falling rocks, and the sound of the Perseverance Wheel moving or drilling into the surface of Mars.
Audio can also signal to scientistsIt is running and it is possible to identify problems with the rover. However, due to the harsh conditions on Mars, scientists warned that the microphone may not continue for the duration of the mission.
Thomas Zurbuchen, deputy director of NASA’s Science Mission Division, said these recordings are “the closest way you can get to Mars without wearing a pressure suit.”
Scientists have tried to hear the sound of Mars. The microphone failed to reach the Red Planet-Mars polar lander twice, and the microphone on the Phoenix lander was never turned on.
In 2018, NASA’s Insight Mars lander accidentallyUse its air pressure sensor and seismograph to analyze the vibration of Martian wind. However, Hengxin captured real objects from the surface of Mars using “commercial” microphones specifically designed to pick up audio.
