Pasadena, California. This is the last time we see a selfie of the NASA Insight spacecraft on Mars. And judging by the amount of dust covering the lander’s solar panels, it’s easy to see why.
The stationary spacecraft took the picture on April 24 with its robotic arm, which will soon be placed in its final resting position, called “retirement mode” this month. To take a selfie, the hand must move several times, and this is no longer possible.
“Before losing more solar energy, I spent some time observing the environment and took one last selfie before putting my camera hand in the stowed position for good,” says InSight. hilro Tuesday.
Due to the depletion of energy reserves, the mission will stop scientific work until the end of the summer. Since landing in November 2018, it has been revealing the mysterious inner regions of Mars.
InSight’s solar panels are increasingly covered in red Martian dust, despite the creative efforts of the mission team on Earth. This accumulation will only intensify as Mars enters winter, when more dust rises into the atmosphere.
These floating particles reduce the amount of sunlight available to charge the solar panels that power InSight, which is currently on an extended mission that was scheduled to last until December. The mission achieved its main objectives after the first two years on the surface of Mars.
The final selfie shows the probe covered in much more dust than previous selfies taken in December 2018 and April 2019.
The lander went into safe mode on May 7 when its power level dropped, 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 is only able to harvest about one-tenth of the available power after landing on Mars in November 2018. When InSight first landed, it could generate about 5,000 watt-hours per day on Mars. turn on the electric oven for 1 hour 40 minutes.
The probe now generates 500 watts a day, enough to power an electric oven in just 10 minutes. If 25% of the solar panels are cleared, InSight will see enough power to keep going. The spacecraft saw several dust vortices or tornadoes, but none of them were close enough to remove the solar panels.
“We were hoping to get rid of the dust, as we’ve seen several times with 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 for us to focus on making the most of the scientific data we can still gather.”
By the end of the summer, the team will shut down the seismograph, complete science operations, and monitor the probe’s remaining energy levels. 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 turned back on.

“Even as we near the end of our mission, Mars is still giving us the opportunity to see some really amazing things,” Banerdt said.
Data collected by InSight so far Learn new details about strangers Core, inner layers and crust of Mars. He also recorded weather data and analyzed the remnants of the magnetic field that once existed on Mars.
The constant flow of data from InSight to scientists on Earth will be interrupted when the solar panels can’t generate enough power. But researchers will be studying the discoveries made by InSight over the next few decades to learn as much as they can about our mysterious planetary neighbor.
