Diligently records the sound and its descent on Mars in pictures

Diligently records the sound and its descent on Mars in pictures

NASA on Monday released two exceptional documents captured by the rover of its perseverance on Mars: an amazing video of its landing from all angles, and the sound of a roar of the Martian wind, the first audio recorded by a mic on the red planet.

Its mission, to find evidence of ancient life on Mars, which landed last week, was the first phase of a journey of at least two years, during which time it will take samples to be brought back to Earth by an Earth. Will be analyzed.

More than three minutes later, the video released by the US space agency reveals images of several cameras located at different locations in the module, after entering the Martian atmosphere. One shows the use of supersonic parachute, the other, located under the rover, approaches Mars soil, and two shots capture the rover gradually landing on the ground, which was suspended from the descent by three cables.

“This is the first time we have been able to capture an event like landing on Mars,” Michael Watkins, director of the renowned Jet Propulsion Laboratory built by Rover, told a news conference. “It’s so awesome.”

Videos aimed at the general public and scientists

The rover was protected by a thermal shield as it entered the atmosphere at a speed of 20,000 km per hour, marking the beginning of the “seven-minute terror” on the ground. You can see in the video that this shield fell on the surface of Mars.

Eight retro-rockets then finished slowing down the vehicle, and Mars dust was injected heavily under their effect. Once the rover is stationary, you can see the final thrust of the landing stage, which will crash at a distance of 700 meters.

“These images and videos are something we have dreamed of for years,” said Alan Chen, NASA’s landing phase manager. In addition to showing the general public how such a serious maneuver can take place in real life, these images will allow NASA teams to better analyze what happens at each stage of future landings.

Air captured on the surface of Mars

NASA believed it could capture the sound of vertigenous descent, but it didn’t work. An unusual audio was recorded as the rover landed on the surface of the Red Planet, however released. In the clip, we can hear a noise made by the rover, but, apparently, Mars wind.

“Yes, you heard an air pressure on the surface of Mars, which was captured by a microphone and sent back to Earth,” said Dave Cruel, the instructor in charge of NASA. These are “the first sounds recorded on the surface of Mars,” he added. The space agency made the same sound, but with the rover’s roar.

Diligently took home two microphones, one of which is housed in the Super Game Science Tool, a sophisticated shoebox-sized camera. This can be used to analyze the noise generated when the super laser laser rock designed by the French hits.

“We hope to continue to use these microphones to capture sound,” said Dave Cruel, whose lifespan is short due to the extreme temperatures on Mars. Previous missions had already failed to accomplish the goal and attempted to send microphones to the Red Planet.

Diligently 5,000 orders

NASA’s Insight robot, which landed on Mars in November 2018, recorded several earthquakes, thanks to a hyper-sensitive seismometer, which Earth people were able to hear. The frequency of vibrations was very low for the human ear; So the recordings were processed and expedited into an audible thanks to a technique called “sonification”.

Jessica Samuels, who heads operations on the surface of Mars, said, “Perseverance is healthy. “We have executed 5,000 orders,” he explained. “All of our tools have passed their initial verification tests and we are pleased that they are all performing as expected.”

In the coming days, diligence will move for the first time, and then the test will continue. Landing site Jessero Greater is always dangerous, Due to its relief. But this is very interesting to scientists because in it, about 3.5 billion years ago, a deep lake ran into a river.
