Pasadena, Calif. — This is the last we’ll see a selfie of NASA’s Insight lander on Mars. And from the amount of dust covering the landing craft’s solar panels, it’s easy to see why.
The stationary spacecraft captured the image on April 24 with its robotic arm, which will soon be placed in its final resting position called “retreat mode” this month. To take a selfie, the arm would have to move several times, and that would no longer be possible.
“Before I lost more solar energy, I took some time to soak in my surroundings and took the last selfie before resting my arm permanently with the camera in the folded position,” says InSight. to babble Mardi.
Due to dwindling energy supplies, the mission will cease scientific work by the end of the summer. It reveals the mysterious interior of Mars since its landing in November 2018.
InSight’s solar arrays are increasingly coated in Martian red dust, despite the mission team’s creative efforts on Earth. This buildup will only get worse as Mars now enters winter, when more dust rises into the atmosphere.
These floating particles reduce the sunlight available to charge the solar panels powering InSight, which is currently on an extended mission that was scheduled to last until December. The mission has achieved its main objectives following its first two years on the surface of Mars.
The final selfie shows the lander covered in much more dust than previous selfies in December 2018 and April 2019.
The lander entered safe mode on May 7, when its energy levels plummeted, causing all but essential functions to shut down. The team expects this to happen more frequently in the future as dust levels increase.
The stationary lander can only collect regarding a tenth of its available power following landing on Mars in November 2018. When InSight first landed, it might produce regarding 5,000 watt-hours per day on Mars, or regarding that needed to function. Electric oven for 1 hour and 40 minutes.
Now the probe produces 500 watts per day, which is enough to power an electric furnace for just 10 minutes. If 25% of the solar panels are cleaned, InSight will see enough power to continue operating. The spacecraft saw several dust devils, or tornadoes, but none of them were close enough to remove the solar panels.
“We were hoping to clean up dust like we’ve seen repeatedly for the Spirit and Opportunity spacecraft,” Bruce Banerdt, InSight principal investigator at NASA’s Jet Propulsion Laboratory, said in a statement. “It’s still possible, but the energy is low enough that our goal is to make the most of the science we can still collect. »
By the end of the summer, the team will shut down the seismometer, end science operations, and monitor the remaining energy levels on the probe. At the end of the year, the InSight mission will end.
However, the InSight team will continue to listen for any potential communication from the spacecraft and determine if it can be reignited.

“Even though we’re nearing the end of our mission, Mars still offers us some really amazing things to see,” Banerdt said.
Data collected by InSight so far Discover new details regarding the unknown The core, inner layers and crust of Mars. He also recorded weather data and analyzed remnants of the magnetic field that once existed on Mars.
The constant flow of data to scientists on Earth from InSight will stop when solar cells cannot generate enough power. But researchers will study the discoveries InSight has been making for decades in order to learn as much as possible regarding our mysterious planetary neighbor.
