From India Today Web Desk: After listening to bubbling sounds beneath the surface and documenting one earthquake after another, NASA’s internal exploration using seismic probes also known as InSight Mars landers are in the last stages of their life on the planet. The lander’s solar arrays were covered in Martian dust that damaged its battery recharging ability, which would ultimately end its mission.
“Here near the end as dust builds up on the solar panels making power generation difficult,” the spacecraft tweeted as it barely held on for the final show with power dropping rapidly and most science now fully operational. blocked.
Explaining why a dust mop could not be added to the rover, the mission team said it would add cost, mass and complexity to the entire mission, and that the most cost-effective way to achieve the goal would be to carry large enough solar arrays. . lead the whole mission.
The solar arrays do their job, and while the mission is aiming for a Martian year (about two years on Earth), the InSight lander is working to double the mission schedule once it lands on the Red Planet. The spacecraft detected and confirmed more than 1,300 seismic events, and more than 50 of them had signals clear enough for the teams to extract information about their location on Mars.

InSight has gathered new insights into Mars’ three main layers: the crust, mantle and core. Scientists found that the crust beneath InSight was slightly thinner than expected. It also probed the upper mantle using seismic waves that travel about 800 kilometers deep before returning to the surface.
“Determining the composition and structure of the layers, and the rate at which heat escapes from them, helps us better understand the geological history of the Martian surface, and in particular its ability to sustain life over time,” said the NASA. The spacecraft also detected magnetic signals on the arid world of Mars, indicating that early in its history, the planet had electric currents flowing through its liquid metal core.
While the lander is exposed to dust demons adding to the deadly dust buildup on its panels, the lander collects the most comprehensive weather data from any mission sent to the Martian surface. Its tentacles have detected the passage of thousands of dust demons.
The mission is now focused on preserving its data set and making it accessible to researchers around the world. NASA was about to declare the mission over when InSight lost two consecutive communication sessions with the spacecraft orbiting Mars. However, the cause of the connection loss must be the probe itself.
