Should all go according to plan, NASA models of the perseverance of the Rover will descend through the atmosphere of Mars in February 2021, to reach a speed of more than 13,000 miles per hour. After landing, NASA engineers will instruct the Rover to improve its high mast, above, in addition to some of the important exploration instrument is a microphone.
The Rover’s launch is now imminent, because the window is blasting into space opens up on July 30th. On reaching Mars the robot’s main task is to search Jay Chak Roshan(an old lake bottom)for signs of past microbial life, and also collected soil and rock behind the mission Shuttle back to Earth. And as the Rover the rumble of the Mars terrain, it will record the weird, alien sound—a truly rare space exploration.
“We think we will hear similar to Earth’s sound, on a planet millions of Miles,”said Bruce Betts, a planetary scientist in the Planetary Society, an organization that promotes the exploration of space.
Rover 15 mm of the microphone is expected to pack the whoosh of the Martian wind, and like the dust devil, they should cross the path with perseverance. The microphone will also record the sound of the Rover jump Mars rock laser, detected some of the rocks from 25 feet away. This laser bombardment, in fact, is why NASA approved the microphone at all. The microphone on perseverance is not really romantic use Hear Mars.
Spaceship on the car is limited and valuable, so NASA requires a microphone(or most things in perseverance)has a scientific purpose, to explain the said Roger Wiens, a planetary scientist at the Los Alamos National Laboratory leadership SuperCam. (SuperCam is with a laser-shooting instrument on the car microphone.) Wiens’s team, however, found a science purpose of a microphone: when the laser shoot the soft rock leaving a small pit, which makes the different The pop-up Sound than the laser kill in Hard Rock. This sound is one that can identify the rocks, give NASA better information about the most promising places to visit in the vast Martian desert.
“We can determine the hardness of a rock, and that’s without even driving it,”said Wiens, he pointed out, knowing that a rock of the hardness of the lead to know what.
However, with the approval of the scientific purpose, now comes a new way to feel the Mars, super-visual the big picture of Mars ‘ canyons, hills and the sunset beams back to Earth in the past few decades. The Rover will record the sound for three and a half minutes of time.
“We can see things on Mars,”said Wiens. “We want to hear about things on Mars.”
“We want to hear about things on Mars.”
But what are recorded in Mars will be different voices to the same sound will be on Earth. That’s because the Martian atmosphere much thinner than Earth, but it also constitutes a major different gas, carbon dioxide. (The Earth’s atmosphere is mostly nitrogen and oxygen.) A thin atmosphere means that the sound has less of a medium, by(the space and the moon where no atmosphere is silent). So, the Martians sound will be more quiet, will not travel almost as those on Earth. One called Earth, traveling more than a kilometer of the journey are just some of the 16 on Mars.
“It’s just a different place,”said Betts.
The thin Martian air will change the sound of the tone, too. “The speed of sound is slower on Mars,”explained Wiens, which results in reduced pitch. On Mars a high slope Annihilator Or pop (We expect to hear on Earth)will sound more like down the Toms in a drum set, he said.
Perseverance is not the first time that human efforts to record Martian sounds. But it might be the first one to succeed. “We’ve been trying to get a microphone on Mars for over 20 years,”said Betts.
The Mars landing of the polarity, with a microphone, by the Planetary Society, crashed into a Martian desert in 1999. Due to electronic problems, NASA has never activated the microphone on the Phoenix lander, which settled on Mars in 2008.
Mankind has been to capture the segment of the sound before in other worlds—just not very much. In 1981, the Soviet Venera 13 and 14 of the detector recording full of static light wind on Venus, in the planet’s crushing atmosphere and the pizza oven-like heat damage to the landing controller. They only lasted 127 minutes and 57 points, respectively. “Venus is a very hostile place,”noted Bill Barry, NASA’s main historian. Nearly a quarter of a century later, in 2005, the Huygens probe successfully parachuted through the thick atmosphere of Saturn’s fascinating moon,Titan. One of Mike shooting the noisy sound of the subsequent descent.
“This is what the traveller can and Huygens would have heard the drop,”writes NASA.
The microphone on the side of the perseverance car to record the car drops through the atmosphere, which means that the mission has two microphones.
This is a microphone on the perseverance, however, this will record Martian sounds, as the Rover explores the Jay Chak Roshan, wherein some of the 3. 5 billion years ago, River drainage, the creation of a lake, perhaps a family of the original Life.
The microphone is not usually a priority to explore other worlds. “The microphone has been at the bottom of the list,”said NASA’s Barry. But now, the microphone to get a real gun.
