The mole's design was based on Martian soil examined by previous spacecraft. That turned out nothing like the clumpy dirt encountered this time.
InSight's French seismometer, meanwhile, has recorded nearly 500 Marsquakes, while the lander's weather station is providing daily reports. On Tuesday, the high was 17 degrees Fahrenheit (minus 8 degrees Celsius) and the low was minus 56 degrees Fahrenheit (minus 49 degrees Celsius) at Mars' Elysium Planitia, an equatorial plain.
The lander recently was granted a two-year extension for scientific work, now lasting until the end of 2022.
InSight landed on Mars in November 2018. It will be joined by NASA's newest rover, Perseverance, which will attempt a touchdown on Feb. 18. The Curiosity rover has been roaming Mars since 2012.
