As Perseverance makes tracks, NASA must plan its next Mars move

March 10, 2021, 3:00PMNuclear News

NASA’s Mars 2020 Perseverance rover took its first drive on the surface of Mars on March 4, traversing 21.3 feet and executing a 150-degree turn in about 33 minutes. The drive was one part of an ongoing check and calibration of every system, subsystem, and instrument on Perseverance, which landed on Mars on February 18.

The NASA team has also verified the functionality of Perseverance’s instruments, deployed two wind sensors, and unstowed the rover’s 7-foot-long robotic arm for the first time, flexing each of its five joints over the course of two hours.

With relatively little fanfare, the functionality of Perseverance’s radioisotope thermoelectric generator (RTG)—assembled at Idaho National Laboratory and fueled by the decay of plutonium-238—is also being proved. It is reliably providing the power that Perseverance’s mechanical and communication systems require.

NASA’s radioisotope-powered science will persevere on Mars

NASA mission control and space science fans around the world celebrated the safe landing of the Mars 2020 Perseverance rover on February 18 after a journey of 203 days and 293 million miles. Landing on Mars is difficult—only about 50 percent of all previous Mars landing attempts have succeeded—and a successful landing for Perseverance, the fifth rover that NASA has sent to Mars, was not assured. Confirmation of the successful touchdown was announced at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., at 3:55 p.m. EST.

“This landing is one of those pivotal moments for NASA, the United States, and space exploration globally—when we know we are on the cusp of discovery and sharpening our pencils, so to speak, to rewrite the textbooks,” said acting NASA administrator Steve Jurczyk. “The Mars 2020 Perseverance mission embodies our nation’s spirit of persevering even in the most challenging of situations, inspiring, and advancing science and exploration. The mission itself personifies the human ideal of persevering toward the future and will help us prepare for human exploration of the Red Planet.”

Only radioisotope thermoelectric generators (RTG) can provide the long-lasting, compact power source that Perseverance needs to carry out its long-term exploratory mission. Perseverance carries an RTG powered by the radioactive decay of plutonium-238 that was supplied by the Department of Energy. ANS president Mary Lou Dunzik-Gougar and CEO and executive director Craig Piercy congratulated NASA after the successful landing, acknowledging the critical contributions of the DOE’s Idaho National Laboratory, Oak Ridge National Laboratory, and Los Alamos National Laboratory.

ANS congratulates NASA for the successful landing of Perseverance on Mars. We look forward to watching from afar its exploration of the Red Planet and search for past microbial life. This is a proud moment as well for nuclear science and technology as a multi-mission radioisotope thermoelectric generator will be powering the rover to mission success.

DOE lists five stories to watch in 2021

Despite all the challenges of the COVID-19 pandemic, the U.S. nuclear energy community pulled out some big wins in 2020, and this year could be even bigger, according to the Department of Energy’s Office of Nuclear Energy.

From deep space exploration on Mars to a historic new reactor coming online in Waynesboro, Ga., 2021 will be a record-breaking year for the industry—both good and potentially bad.

The launch of the Mars 2020 Perseverance rover went ahead as scheduled on July 30, lifting off from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida at 7:50 a.m. (EDT) . The rover was onboard a United Launch Alliance Atlas V 541 rocket.

Minutes later, NASA reported that all flight milestones were being met as planned. There are several more milestones to reach before Perseverance—the fifth rover that NASA has sent to Mars—lands on the Red Planet in seven months.

One small step for fission—on the Moon and beyond

July 27, 2020, 12:02PMNuclear News

A reliable energy source is critical for long-duration space exploration. NASA, targeting launch readiness by the end of 2026, has teamed up with the Department of Energy and Idaho National Laboratory to solicit realistic assessments of fission surface power systems designed for deployment on the Moon that could, with little modification, be sent to Mars as well.
