NASA’s patience drives Martian terrain for the first time-ScienceDaily

NASA’s Mars 2020 Perseverance Lance made its first drive on Mars on March 4, covering 21.3 feet (6.5 meters) across the Martian landscape. The drive acted as a mobility test that was just one of many milestones when team members checked out and tuned all Perseverance systems, subsystems, and equipment. As Rover begins to pursue scientific goals, regular commute over 656 feet (200 meters) is expected.

“For wheeled vehicles on other planets, there are few first events to measure the importance of the first drive,” said Mars 2020 Perseverance Rover Mobility Testbed Engineer at NASA’s Jet Propulsion Laboratory in Southern California. Anais Zarifian said. California. “This was my first chance to” kick the tires “and spin the perseverance. Rover’s 6-wheel drive responded brilliantly. Now I am confident that a drive system that will take us wherever science guides us will work. In the next two years “

The drive, which lasted about 33 minutes, propelled the rover 13 feet (4 meters) forward, where it was rotated 150 degrees to the left and retracted 8 feet (2.5 meters) into a new temporary parking space. To better understand the dynamics of retrorocket landing on Red Planet, engineers used Perseverance’s navigation and hazard avoidance cameras to image where Perseverance landed and engine the dust on Mars. Distributed with a plume from.

More than roving

Rover’s mobility system does more than just test drive during this first checkout period. On February 26, eight days after the landing of Perseverance, Zol, the mission controller completed a software update, turning the computer program that assisted the landing of Perseverance into a computer program that relies on planetary exploration. I replaced it.

More recently, the controller has checked out the Perseverance Radar Imager (RIMFAX) for Mars underground experiments and the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) equipment, and the Mars Environmental Dynamics Analyzer (MEDA) equipment. Deployed two wind sensors. From the rover mast. Another important milestone is on March 2nd or Sol 12 where engineers unleashed the rover’s 7-foot-long robotic arm for the first time and bent each of its five joints over a two-hour period. It has occurred.

“The first test of the robotic arm on Tuesday was a big moment for us,” said Robert Hogg, Deputy Mission Manager for the Mars 2020 Perseveran Rover. “This is the primary tool used by science teams to perform close-up examinations of Jezero Crater’s geological features. Next, drill and sample what appears to be the most interesting. The robot arm bends. Muscles with beautifully functioning images after a long trip to Mars once confirmed to be-well, that made my day. “

For upcoming events and evaluations, more detailed testing and calibration of scientific instruments, transmission of rover on longer drives, protection of both adaptive caching assembly (part of rover’s sample caching system) and Ingenuity Mars Helicopter during landing Includes dumping cover. Ingenuity Mars Helicopter’s experimental flight test program will also be conducted during the rover’s commissioning.

Throughout all that, Rover is sending images from the most advanced camera suite ever to travel to Mars. The mission camera has already sent about 7,000 images. On Earth, images of Perseverance flow through a powerful Deep Space Network (DSN) managed by NASA’s Space Communications and Navigation (SCaN) program. In space, several Mars probes play equally important roles.

“Orbiter’s support for data downlinks was a true game changer,” said Justin Maki, chief imaging engineer and imaging scientist at JPL’s Mars 2020 Perseverance Lance Rover Mission. “When you see a beautiful image from Jezero, think of the entire Martian team as it took to get it. All photos from patience are from the European Space Agency’s Trace Gas Orbiter, or NASA. Broadcast by either MAVEN, Mars Odyssey, or Mars Reconnaissance Orbiters. They are important partners in our exploration and discovery. “

The vast amount of images and data already descended on this mission waits for the first image to drip during Sojana, NASA’s first Mars probe mission to explore Mars in 1997. It’s a welcome benefit for Matt Wallace, who remembers what he was doing. 3, Wallace has become the new project manager for the mission. He replaced John McNamie, who resigned as intended after directing the project for nearly a decade.

“John has been providing unwavering support to me and all members of the project for over a decade,” says Wallace. “He left his mark on this mission and team, and it was my privilege to call him my friend as well as my boss.”

Named touchdown site

With Perseverance moving away from the touchdown site, mission team scientists commemorated the location and informally named it after the late science fiction writer Octavia E. Butler. A groundbreaking writer from Pasadena, California, she was the first African-American woman to win both a Hugo Award and a Nebula Award, and the first science fiction writer to win a MacArthur Fellowship. The place where Perseverance began its mission on Mars is now named “Octavia E. Butler Landing”.

The official scientific names of locations and objects throughout the solar system, such as asteroids, comets, and locations on planets, have been designated by the International Astronomical Union. Scientists working with NASA’s Mars rover have traditionally given informal nicknames to various geological features and can be used as a reference for scientific papers.

“Butler’s protagonist embodies determination and ingenuity, which fits perfectly with the theme of the Perseverance Rover mission and overcoming its challenges,” said Catherine Stack Morgan, a deputy project scientist at Perseverance. I will. “Butler has influenced the planetary science community and many other communities, including those that are generally undervalued in the STEM space.”

“It’s as good as Octavia E. Butler, who not only grew up next to JPL in Pasadena, but also inspired millions of people with a science-based vision of the future to mark this historic landing site. I don’t think there are any people, “Thomas said. Zurbuchen, Associate Administrator of NASA Science. “Her guideline,’When you use science, do it exactly,’ is all about NASA’s science team. Her work continues to inspire today’s scientists and engineers around the world. These are all bolder and fairer names. The future of everyone. “

Butler, who died in 2006, wrote prominent works such as “Kindred,” “Blood Child,” “Speech Sound,” “Parable of the Sower,” “Parable of the Talent,” and “Patternist.” Did. Her writings explore the themes of race, gender, equality, and humanity, and her work is as relevant today as it was when it was first written and published.

Mission details

The main purpose of Perseverance’s mission on Mars is astrobiology, which involves exploring the signs of life of ancient microorganisms. Rover will be the first mission to characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and collect and cache Martian rocks and regoliths.

Subsequent NASA missions will work with the ESA (European Space Agency) to send spacecraft to Mars, collect these sealed samples from the surface, and return them to Earth for further analysis.

The Mars 2020 patience mission is part of NASA’s lunar-to-Mars exploration approach. This includes a mission to the Moon in Artemis to help humans prepare for the exploration of the Red Planet.

Managed for NASA by the California Institute of Technology in Pasadena, JPL builds and manages the operation of the Perseverance Rover.
