As the rover of the next NASA general leads the curiosity of the older sister

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

NASA has once again sent what belongs to the final driverless car to Mars. perseverance, rover formerly known as March 2020, left Earth on Thursday to become NASA̵

7;s next Curiosity robot, which has been roving the red planet since 2012.

This latest-generation planetary explorer comes from a long line of well-traveled bots with some major updates on its older sister that should allow scientists to see, touch and – for the first time ever – hear Mars in ways News.

Martian audio-visual club

A variety of rovers and Mars orbiters have sent a host view of the red planet house, but we have yet to open a microphone there to pick up the sounds of our neighboring planet. Perseverance aims to eventually change that, carrying a pair of friends who will take the sound of landing on the planets, as well as the noise of another world environment and the nap of a rover at work.

“Hearing how the mast turns, the wheels turn, or hearing how other instruments sound can also be an important engineering diagnostic tool,” said Greg Delory, CEO and co-founder of spacecraft company Heliospace. He is a consultant on Perseverance’s SuperCam microphone team.

The SuperCam is the rover’s new scientific instrument that explodes rock and other materials with a laser as its microphone records the subtle sounds produced by different types of rock as they disappear. The MicCC SuperCam will also be able to pick up Martian wind and other sounds from the rover environment.

Another friend on board is part of the entry, descent and landing system that includes full-color cameras to capture the entire thrilling ride down to the surface.

All together, the insistence is loaded with 23 cameras, most of them color equipment. It will be able to capture HD video and 3D stereo panes and zoom in on a target the size of a house fly from over 100 meters (91 meters) away.

Save it for later

A key part of the mission of perseverance is the collection of rock and gas samples from the Martian surface, which will then be secured for possible subsequent return from a future mission.

A considerable part of the rover’s abdomen is taken from instruments for the collection and analysis of 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,” planetary scientist Caroline Smith of the UK Museum of Natural History said in a statement. . Smith is working with NASA and the European Space Agency to plan how the samples will be cured after they are delivered to Earth.

The champion’s return mission is part of one of the biggest goals for perseverance – looking for evidence of past life on Mars. Crater Lake, where the rover will land, is thought to have once been home to a large body of water the size of Lake Tahoe, making it a major site for life in the distant past.

A flying attacker

The insistence will be entirely based on Mars, but it is holding something new and exciting: the first helicopter to match the exquisite atmosphere of our neighboring planet.

Called the English, the small machete is placed in the belly of the rover, to be expelled to the surface for some flight tests. This must be very interesting as we have never flown to another planet and the atmosphere of Mars is very different from that of Earth.

To put it another way, do not expect too much from this little drone tool. But if it works, it could mean upswing (badly) to the way we explore other worlds in the future.

Preparing for Elon and other human visitors

One of the stated goals of the mission of perseverance is to make major advances that will support the future arrival of current people to become the first (or at least most recent) Martians.

The rover is equipped with experiments like Moxie, the Experiment of Using Oxygen Resources on Mars of Oxygen on Mars, which will test a way to draw oxygen from thin Martian air. It will also use instruments to see how ubiquitous dust in that air can affect human life support systems and other key technologies.

Still other experiments will look for water below the surface, study the Martian atmosphere, climate and weather, and assess their impact on potential human explorers.

New fancy wheels and a stronger arm

The engineers took some lessons from Curiosity and the punishment he gave her from the sharp, spicy Martian rocks and applied them to increase the wheels in Perseverance. They are narrower but have a larger diameter and are made of thicker aluminum. This, and all her new tools, make perseverance heavier than her older sister and sister.

Using all of those tools also requires a larger “hand” or turret at the end of its robotic arm. The arm stretches 7 meters (2 meters), ending in the 99-kilogram (45-kilogram) turret that holds a scientific camera, chemical analysts and rock drills. Almost too many gloves of ultimate power.

Curiosity had a similar composition, but the turret in perseverance weighs 33 percent more because it has larger instruments and a drill aimed at cutting into intact rock cores to collect samples for storage.

In general, perseverance is the most advanced robot to visit Mars yet, and if all goes well, it could be one of the last to make the journey alone without human companions.
