NASA says it is retiring its InSight Mars lander mission, after over four years of collecting data on the red planet.

InSight recently fell silent for the first time since arriving on Mars, its power levels had been dwindling for months because of dust coating its solar panels.

InSight landed on Mars in 2018 and was the first spacecraft to document a marsquake.

It detected more than 1,300 marsquakes with its French-built seismometer, including several caused by meteoroid strikes.

The most recent marsquake sensed by InSight, earlier this year, left the ground shaking for at least six hours, according to NASA.

The seismometer readings shed light on Mars’ interior.

Just last week, scientists revealed that InSight scored another first, capturing a Martian dust devil not just in pictures, but sound.

In a stroke of luck, the whirling column of dust blew directly over the lander in 2021 when its microphone was on.

The lander’s other main instrument, however, encountered nothing but trouble.

A German digging device—meant to measure the temperature of Mars’ interior—never made it deeper than a couple feet (half a meter), well short of the intended 16 feet (5 meters).

NASA declared it dead nearly two years ago.

InSight recently sent back one last selfie, shared by NASA via Twitter on Monday.

The lander’s power levels have been dwindling for months because of all the dust coating its solar panels.

NASA still has two active rovers on Mars: Curiosity, roaming the surface since 2012, and Perseverance, which arrived early last year.

Perseverance is in the midst of creating a sample depot; the plan is to leave 10 tubes of rock cores on the Martian surface as a backup to samples on the rover itself.

NASA plans to bring some of these samples back to Earth in a decade, in its longtime search for signs of ancient microscopic life on Mars.

Perseverance also has a companion: a mini helicopter named Ingenuity.

It just completed its 37th flight and has now logged more than an hour of Martian flight time.
