Earth planning date: Monday, Jan. 27, 2025
Today was an exciting day for me as the lead of the Geology and Mineralogy Science Team. It kicked off with a rare winter thunderstorm here in England. Just as the power flickered out for a few minutes, my trusty laptop and phone kept things running smoothly. Let’s keep that little power hiccup between us!
Today’s planning session was particularly captivating. We faced an important choice: Should we align ChemCam and APXS observations for one target, or spread them across two different targets? My job is to lead this discussion, and I always enjoy hearing the well-prepared arguments from my colleagues. Each person brings unique insights about Mars and geology. After weighing the options, we opted for coordinated observations on a bedrock target we named “Desert View.” APXS will kick things off, followed by some active ChemCam work and an RMI image, then MAHLI will close by imaging the APXS target, which will have laser pits by then.
This teamwork in observations helps us understand how the rock responds when hit by the laser. We’ve learned fascinating details about the mineral composition of these rocks over the years. I’m reminded of a remarkable achievement from a decade ago when we captured the moment a laser sparked on a target called “Nova.” It not only served engineering purposes, but it also sparked my curiosity about the rock’s reactions.
Back to today! Besides our main targets, ChemCam will enhance the Remote Micro Imager’s coverage of Gould Mesa with a vertical RMI observation. This will provide a rich look at the different layers in the mesa. Meanwhile, Mastcam will capture new perspectives of the Rustic Canyon crater. By observing craters from various angles, we can uncover more about their structure and the geological history they reveal.
Mastcam will also create mosaics of “Condor Peak” and “Boulder Basin.” We’re interested in these locations to check for any changes in structures or textures over time. Mars often surprises us, so we keep a close watch to see if anything shifts. We love to analyze how various rock formations are positioned. The grayscale Navigation Camera image captures some of these fascinating blocks we’re studying.
Once our targeted science is done, the rover will continue its route to explore more of what Mars has in store. After moving, MARDI will snap an image while ChemCam carries out an autonomous observation. Additionally, we’ll conduct atmospheric checks to monitor dust levels and look for dust devils. Other instruments like DAN will constantly observe the surface, measuring wind and temperature.
With today’s plan, we’ll make the most of our available power. As for the weather, it’s cleared up inside, and outside, it’s back to the typical English rain. Always an adventure!
