NASA’s new rover has recorded its own audio recording of a crash on the surface of the Red Planet, adding a new dimension to Mars exploration.
As the Perseverance Rover began to make tracks on the surface of Mars, it created the first sensitive microphone to carry: six-wheeled rattles of barangays, pings and robots, when it landed on Martian terrain.
“When a lot of people look at the images, they won’t appreciate that the wheels are metal,” said Vandi Verma, a senior engineer and rover driver at NASA’s Jet Propulsion Laboratory in Southern California. “When you drive on rocks with these wheels, it’s really very noisy.”
More than 16 minutes of noise from the Perseverance’s 90-foot (27.3-meter) drive on March On were captured by Perseverance’s Entry, Descent and Landing (EDL) microphone, operating on the Rover after its historic historic touch on February 18th. The f-the-shelf microphone was added to the rover to take people along for a ride during the touchdown, but mission members are also keen to hear sounds from the surface.
“If I had heard these noises driving my car, I would have pulled and called,” said Dave Gruel, lead engineer of the Mars 2020 EDL camera and microphone subsystem. “But if you take a minute considering what you’re listening to and where it’s recorded, it makes perfect sense.”
Two versions of the audio drive clip of the same drive were released on March 17. The first version features more than 16 minutes of raw, muffled sounds of a rover traveling in a Jezero crater. In it, the sound produced by the interaction of the peripheral mobility system (its wheels and suspension) with the surface is heard with a high-scratching sound. Perseverance’s engineering team continues to evaluate the source of the itching noise, which could be an electromagnetic interference from one of the rover’s electronics bucks or an interaction between the mobility system and the Martian surface. The EDL microphone was not intended for surface operation and had limited testing in this configuration prior to launch.
The second version is a short compilation of sounds from a long raw recording of the drive. For this 90-second version, NASA engineers combined three parts from a raw audio dio file (part 0: 20-0: 45, 6: 40-7: 10, and 14: 30-15: 00), processing and editing some of the sound filters in it. .
This first audio of the drive on the Martian surface joins the growing playlist of Dio Mars, who patiently returns to Earth. The second microphone, part of the rover’s supercam instrument, previously made Martian sighs and the instrument’s laser zapping ping rocks made a quick ticking sound to reveal details of its design and composition. Such information will help scientists as they search the Jezero Crater for signs of ancient microscopic life, taking rock and silt samples to return to Earth through future missions.
The supermac sound of the probe passing through the rover was part of a series of systems, from the Mars Environmental Dynamics Analyzer to the giant robotic arm of Perseverance making its first weather observations.
The rover is also searching for the right airfield for the ingenuity Mars helicopter to try for its first flight tests. Now that the right place has been found, the Persians and Tactics teams are planning a rover to deploy a helicopter with five exciting days, or Souls (31 Earth Days).
And then the search for ancient life will begin eagerly, at one point the water exploring with diligence will be covered. Between the Rover’s 19 cameras and its two microphones, the experience will be full of venues and sounds. For Verma, who has helped NASA’s last four Mars rovers “drive”, plan their routes and transmit instructions so they can take a day’s drive across numerous terrain, Audio Dio is more than just cool.
“The difference between Earth and Mars અમને we have a visual sense for that.” “But sound is a completely different dimension: to see the difference between Earth and Mars and to experience that environment more closely.”
