Sol 985: High Tilt
by Ken Herkenhoff Once again, excessive wheel slippage prevented MSL from driving as far as planned, so the tactical team decided to take a break from driving to allow various options to be studied in more detail. The rover is tilted 21 degrees, the highest tilt of the mission so far, on the flank of a small ridge. The vehicle is high enough on the ridge that the terrain to …

Sol 984: Slippery sand
by Ken Herkenhoff The MSL tactical team took a day off yesterday to allow Earth and Mars time to synch up; planning is no longer restricted and we will be working every day the rest of this week (including Saturday). Despite efforts to avoid sandy areas, the Sol 983 drive stopped short when the rover detected that it was slipping too much. So after taking some Mastcam images of …

Sol 983: More sand traps
by Ken Herkenhoff The Sol 981 drive got the rover around the troublesome ripples and to the desired location, which gave us a good view of the terrain ahead. Unfortunately, the images taken from the new location show more sandy ripples between the rover and the sharp transition between bright and dark rocks that we would would like to examine close up. So the plan for Sol 983 is …

Sols 980-982: Dodging Sand, Updating ChemCam
by Ryan Anderson The Sol 978 drive stopped after going only a couple meters instead of the expected ~19 meters because Curiosity detected that its wheels were slipping in the sand. The rover periodically takes pictures of its surroundings while driving to make sure that it is actually moving forward and its wheels are not just spinning in place. This was a lesson learned years ago when the Opportunity rover …

Sol 978-979: Jocko Chute
by Ryan Anderson The sol 976 drive was successful and we are close to “Jocko Chute” (our informal name for the saddle point west of Jocko Butte). In the sol 978 plan, we have a ChemCam LIBS observation of a patch of exposed bedrock called “Big Salmon”, followed by lots of Mastcam images. There is a 14×3 mosaic of some hills in the direction of our drive, some single frame …

Sols 976-977: Onward to Jocko Butte
by Ryan Anderson With our weekend contact science done, it’s time to hit the road again. The sol 976 plan includes some final Mastcam mosaics of the interesting outcrops that we have been studying, plus a Mastcam multispectral observation of the target “Albert” that ChemCam zapped over the weekend. After that, we will drive about 60 m, to a location west of “Jocko Butte”. After the drive we have post-drive …

Sol 973-975: Albert, Bigfork, and Charity
by Ken Herkenhoff MSL is in a good position for contact science observations on an interesting outcrop of sedimentary rock, so the rover will be busy this weekend! We had to change the timing of the arm activities a bit to optimize the illumination of MAHLI targets, so it was a busy morning for me as SOWG Chair but I’m happy with the way the plan turned out. On …

Sol 971-972: Approaching outcrop
by Ken Herkenhoff This morning the MSL science team used all of the available data to decide whether to approach one of the nearby outcrops or drive away. Ultimately we decided to approach the closer of the large outcrops in front of the rover to set up for contact science this weekend. Planning is still “restricted,” so we planned two sols of activities today. ChemCam and Mastcam will observe …

Sol 969-970: Studying Mt. Shields
by Ryan Anderson Our drive on sol 967 covered almost 90 meters, putting us in front of some interesting stratigraphy at “Mt. Shields”, an outcrop along our drive down “Logan’s Run”. In the sol 969-970 plan, we have lots of Mastcam and ChemCam studying the outcrop. On sol 969, Mastcam has a 24×2 stereo mosaic and a 6×3 stereo mosaic of parts of Mt. Shields. Then, on sol 970, ChemCam …

Sol 966-968: More Driving
by Ken Herkenhoff The rover drove 32 meters on Sol 964, to a position that gave us a good view of the terrain ahead and outcrops of interest. So a longer (~90 m) drive is planned for Sol 967 after ChemCam and Mastcam observe nearby targets dubbed “Pablo” and “Pauline” on Sol 966. Mastcam, Navcam and REMS will also observe the atmosphere. I’m MAHLI/MARDI uplink lead today, and planned …
