Researchers found that Mars’ rotation is accelerating by about 4 milliarcseconds per year — making the length of a Martian day shorter by a fraction of a millisecond per year.

The findings are based on seismic measurements from NASA’s Mars InSight lander, which detected more than 1,300 marsquakes before shutting down two years ago.

NASA's Mars lander, called Insight, is slowly losing power because its two solar panels are covered in dust and it will need to mostly shut down by the end of May.

The lander, which has been on the Red Planet since 2018, measured seismic data over four years, examining how quakes shook the ground and determining what materials or substances were beneath the s… ...

Dust blankets the solar panels of the Mars Insight lander, shortly before its demise. NASA The life of the Mars InSight lander came to an end last year as its solar panels were covered with dust ...

This is one of the last images ever taken by NASA’s InSight Mars lander. Captured on December 11, 2022, the 1,436th martian day, or sol, of the mission, it shows InSight’s seismometer on the ...

On May 4, 2022, NASA 's now-retired InSight lander recorded a magnitude 4.7 quake, five times stronger than the previous record holder of magnitude 4.2 that InSight measured in 2021.
