Earth planning Wednesday, Feb. 12, 2025

I woke up this morning to my weather app telling me it felt like minus 15° C (5°F) outside. On days like this, it can take me a little longer to get myself up and out into the world. Curiosity has a similar problem — as we head toward winter and it gets colder and colder in Gale Crater, Curiosity has to spend more time warming up to do things like driving and all our good science. I’ve also been watching a couple winter storms that are expected in the next few days here in Toronto. Luckily, Curiosity doesn’t have to deal with snowstorms, and our drive in the last plan went ahead as planned and put us in a good position to go ahead with contact science today, a relief after having to forego it on Monday. 

The contact science location that the geology team chose is called “Catalina Island,” the flat rock you can see in almost the center of the image above. As you can likely also see above, there’s a whole jumble of rocks in that image, and Mastcam and ChemCam have picked out a couple others to take a look at. These are “Point Dume,” which will be the target of ChemCam’s laser spectrometer, and “Whittier Narrows,” on which Mastcam will image some linear features. Mastcam and ChemCam are also turning their gazes further afield for Mastcam targets “Cleghorn Ridge,” “Cuyamaca Peak,” “Kratka Ridge,” and two long-distance ChemCam mosaics of the top of the Wilkerson butte and a spot a little further down known as “Pothole Trail.”

Much like I’m keeping an eye out the window on the changing weather here, Curiosity is also continuing to keep an eye on the environment in Gale Crater. Even though it’s not the dusty season, we continue to monitor the dust around us and in the atmosphere with a dust-devil survey and a tau. But we’re especially interested in what the clouds are up to right now, which we’re checking in on with our normal zenith and suprahorizon movies, and our cloud-season-only Phase Function Sky Survey. This is a series of movies covering the whole sky that we can use to determine how sunlight interacts with the individual water-ice crystals in the clouds.
