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.
Four years ago, I announced that I was writing a book about Curiosity, describing the mission from its inception through its nominal mission. I am still not done, so am taking a three-month break from other work -- including this blog -- in order to focus and finish. I'm seeking scientists and engineers to serve as guest bloggers.
Behold: Daphnis, the tiny, 8-kilometer moon that orbits within a ring gap, gently tugging on the edges of the gap to create delicate scallops.
Go see Hidden Figures, and bring your kids. Despite its serious subject matter, the movie is joyful, often funny, and, in the end, triumphant.
What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.
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.
ExoMars Trace Gas Orbiter's science team enjoyed the opportunity in November to test out their science instruments on Mars. One of the tests involved imaging Phobos from an unusual angle.
It's been a drive-heavy two months for Curiosity. Since my last update, the rover has drilled at a site named Sebina, then traveled about 500 meters to the south across increasingly chunky-looking Murray rocks to a new attempted drill site at Precipice. They were planning to attempt a new drilling technique at Precipice, but encountered a new problem with the drill instead.
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.
Emily's eighth annual kids' space book recommendation post includes lots of new books for kids of all ages, 0 to 18.
