NASA’s Persistence Mars Rover is sent to its new home on Earth

Did you know NASAIs next Mars Is there nearly one brother on earth to test the rover? Even better, this is the first time a replica of the Martian landscape has been visited.

As NASA’s Mars rover goes into space through the Red Planet, a twin-wheel twin vehicle is set to orbit the Earth.

The full-scale engineering version of the Mars 2020 Perseverance Rover – designed to help it operate autonomously with wheels, cameras and powerful computers – just ran in its garage home at NASA’s Jet Propulsion Laboratory in Southern California Gone. is. This Rover model passed its first driving test in a relatively warehouse-like gathering room. JPL As of September 1, 2020. Engineers hope to take it to Mars Yard next week, where a field of red dirt filled with rocks and other obstacles mimics the surface of the red planet.

NASA’s Jet Propulsion Laboratory in Southern California has a full-scale engineering model of NASA’s Persivice Mars Rover in a garage opposite Marsa Yard. Sincerely: NASA / JPL-CaltechJPL’s mobility bed engineer Anees Zarifian said, “The test mobility team cannot wait for our test rover to finally come out.” “It’s a test robot that comes close to summarizing the actual missions of the mission – on Mars with wheels, eyes and brains – all working together – so it’s particularly fun to work with the rover It is going to happen. . “

Wait, why do twins need to work hard?

Commitment with mechanic is not going to Mars. To avoid as many unforeseen issues as possible after Rover Land on February 18, 2021, the team would need a rover of this Earth-based vehicle system test bed (VSTB) to detect that hardware and software were vulnerable How to send command to Will perform first. MARS This Rover model will be particularly useful for completing an entire set of software tests so that teams can send patches on their way to Mars or once they reach the screen.

And just as a name for determination is a fitting name – one that captures the hard work of getting a rover on its way to Mars in the midst of an epidemic – its twins have a name: optimism. While Optimism is a compendium of the twin’s commitment to work for mechanisms and equipment sent to Mars, the name also endorses the mantra of the team that planned and assembled it for two years.

Matt Stumbo, who leads VSTB Rover in the test bed team, said: “So we named it Test Rover Optimism to remind us of what we need to do to fully test the system. Our job is to find the problems, not just the problems hope Will work As we work on issues with optimism, we gain confidence in our ability to work on Mars. “

Almost consistent

The optimism is virtually identical: it is the same size, has the same mobility system and peak driving speed (0.094 mph or 0.15 km), and represents the same special “head” called the remote sensing mast. It is said. Following the second phase of the building at the beginning of the new year, it will feature a complete set of dedication to “mind” science equipment, cameras and computers, and a unique system for collecting rock and soil samples.

But since optimism remains at JPL, there are some worldly differences. For one thing, while the commitment is powered by a multi-mission radioisotope thermoelectric generator (a type of nuclear battery that has reliably operated space missions since the 1960s), optimism is characterized by an umbilical cord called power Can be plugged for. The cord also provides an Ethernet connection, allowing the mission team to send and receive commands to optimize engineering data without having to set up the radio to use the radio processor for communication. And while Mars’ commitment to keeping warm in cold environments comes with a heating system, optimism relies on a cooling system to operate in hot Southern California.

NASA is strongly pushing Mars Rover Twin

Welcome to the family

Optimism JPL is not the only VSTB rover. NASA’s Curiosity Mars Rover, which has been exploring the red planet since its launch in 2012, has a Maggi (Mars automatic giant Gizmo for integrated engineering). Maggieu is assisting the C Rociti team with particularly challenging areas and drilling rock crossing strategies.

Optimism and Maggie Mars will live side by side in the yard, providing JPL engineers with a two-car garage for the first time.

“Missions that are working need proper replicas of their systems for testing,” Stumbo said. “The Uruguay Mission learned a lesson from Maggie that was impossible for anyone else to learn. Now that we have T-Petism, the commitment mission to learn to succeed on Mars is well laid out. ”

The Astronomy Mission of Perseverance Rover will look for signs of ancient microorganism life. It will also facilitate the planet’s climate and geology, paving the way for human exploration of the Red Planet, and Marathon will be the first planetary mission to collect and capture rocks and regulators (broken rocks and dust). Later missions, currently being considered by NASA in collaboration with the European Space Agency, will send the spacecraft to Mars on Tuesday to collect these cash samples from the surface and on Earth for in-depth analysis.

The Mars 2020 mission is part of a larger program that includes missions as a way to prepare the moon for human exploration of the red planet. Blaming astronauts returning to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA’s Artemis lunar research plans.
