As another Mars rover “Persistence” NASA on top of the older brothers is interesting



persistence-rover

This story is part of it Welcome to Mars, our series explores the red planet.

NASA has once again sent to Mars what is the final car without a driver. Persistence, a rover formerly known as Mars 2020, left Earth on Thursday to become the successor robot to NASO Curiosity, which was traveling the red planet since 201

2.

This latest-generation planetary explorer comes from a long line of well-traveled bots that have major upgrades over their older siblings, which allow scientists to see, touch and – for the first time ever hear Mars in a new way.

The range of Mars rovers and orbits sent a lot view of the house of the Red Planet, but we haven’t actually opened a microphone there to capture the sounds of a neighboring planet. Persistence aims to change this once and for all by holding a pair of microphones that will pick up the sound of landing on the planet, as well as the surrounding noise of another world and the circling noise of the rover at work.

“Listening to the masts spinning, the wheels spinning, or hearing other instruments sound can also be an important tool for engineering diagnostics,” said Greg Delory, CEO and co-founder of Heliospace. He is an advisor to the Supersem Perseverance microphone team.

SuperCam is a new rover science tool that climbs rock and other materials, while its microphone records subtle sounds made by different types of rock as they hit. The SuperCam microphone will also be able to pick up the Martian wind and other sounds from the rover’s surroundings.

Another onboard microphone is part of the entry, descent and landing system, which includes full-color cameras to capture all the exciting movement on the surface.

Altogether, Perseverance is loaded with 23 cameras, most of which are color devices. It will be able to shoot HD video and stereo 3D panoramas, as well as zoom in on a target the size of a house flying from more than 100 meters (91 meters).

Save it for later

A key part of the Persistence mission is to collect samples of rocks and gas from the surface of Martian, which will then be provided for a possible further search for a future mission.

Much of the rover’s abdomen is occupied by devices for collecting and analyzing Martian geology.

“I can’t wait for these unique specimens to one day return to Earth and be available for study by scientists around the world,” said planetary scientist Caroline Smith of the Museum of Natural History. Smith is working with NASA and the European Space Agency to plan how samples will be taken after they are delivered to Earth.

The sample return mission is part of one of the biggest goals of perseverance – finding evidence of past life on Mars. Crater Lake, where the rover will land, it is believed that once there was a large body of water the size of Lake Tahoe, which makes it a great place to live in the distant past.

Flying action movie

Perseverance will be completely grounded on Mars, but it carries something new and exciting: the first helicopter that can jump the subtle atmosphere of a neighboring planet.

The tiny chopper, called the intensity, is placed in the belly of the rover to drive it to the surface for some flight tests. This should be very interesting, because we have never flown to another planet, and the atmosphere of Mars is very different from Earth.

Otherwise, don’t expect too much from this little space drone. But if it works, it could mean big ups (sorry) for how we explore other worlds in the future.

Prepare for Elon and other human visitors

One of the stated goals of the Persistence mission is to achieve key successes that will support the future arrival of real people who will become the first (or at least the last) Martians.

The rover is equipped with experiments such as Moxie, an experiment on the use of resources Mars Oxygen In-Situ Resource, which will test the method of extracting oxygen from the literal Martian air. It will also use tools to study how ubiquitous dust in this air can affect human life support systems and other key technologies.

Other experiments will look for groundwater, study the Martian atmosphere, climate and weather, and evaluate their impact on potential human researchers.

Fashionable new wheels and a stronger hand

The engineers took a few lessons from curiosity and the punishment she was given by the sharp, sharp Martian rocks, and applied them to reinforce the wheels on perseverance. They are narrower, but have a larger diameter and are made of thicker aluminum. This and all his new tools make persistence harder than her older brother.

To use all these tools you also need a larger “hand” or a tower at the end of her robotic arm. The arm extends 2 feet (2 meters) to a rotating 99-pound (45-pound) turret with a scientific camera, chemical analyzers, and rock drill. It is largely a glove of maximum power.

Curiosity had a similar setup, but the turret weighs 33 percent more because it has larger tools and a drill designed to cut into virgin rock cores to collect samples for storage.

In general, “Perseverance” is the most perfect robot to visit Mars so far, and if all goes well, it may be one of the last to make a trip alone without human companions.
