The four-stop dune science campaign offered the engineers some time to continue troubleshooting the drill without any pressure to use it for science. They scooped sand at a site called Ogunquit Beach but couldn't complete the planned sample activity because of new developments in the drill inquiry. The rover has now headed onward toward Vera Rubin Ridge.
Since my last update, the Curiosity mission has developed a better understanding of the problem that prevented them from drilling at Precipice, but its intermittent nature has slowed the development of a workable solution that will allow them to use the drill again. In the meantime, the rover has driven onward, making good use of its other instruments.
Today is the solstice, the longest winter night at Earth's north pole, the longest day of summer in the south. To give a little light to northerners in darkness today, please enjoy this gallery of images of (mostly) sunlit north poles across our solar system.
ESA issued an update on the Schiaparelli landing investigation today, identifying a problem reading from an inertial measurement unit as the proximate cause of the crash. Meanwhile, ExoMars Trace Gas Orbiter is operating its science instruments for the first time this week, and HiRISE has released calibrated versions of the Schiaparelli crash site images.
