Curiosity Blog, Sols 4812-4819: Back Into the Hollows

This is the hidden content, please
NASA’s Mars rover Curiosity acquired this Navcam image looking out towards the northern rim of Gale Crater. Compared to just a few months ago, the view is much hazier, reflecting the higher amount of atmospheric dust that is typical of this time of year. Curiosity captured the image using its Left Navigation Camera on Feb.19 — Sol 4813, or Martian day 4,813 of the Mars Science Laboratory mission — at 12:15:50 UTC.

This has been a pretty routine week for Curiosity. As was

, we’re now in the final phase of the boxwork exploration campaign. We’re currently making our way toward the eastern contact of the boxwork formation with the surrounding geology, which we plan to drive along before turning our attention to the southern contact. That will likely be our last opportunity to directly interrogate the boxwork area before we continue our adventure up the slopes of Mount Sharp.

Along the way, we’ve been performing our usual investigations of the geology that we encounter at our parking locations. As always, this includes contact science on bedrock targets close to the rover, ChemCam LIBS observations of targets slightly further afield, and a number of ChemCam RMI and Mastcam mosaics. These mosaics include observations deeper into the “Tapiche” hollow where we’re parked and the “Los Flamencos” ridge to its south, which we plan on investigating closer in the coming week.

Mars continues to move deeper into its dusty season, so the environmental science group filled this week’s plan with a typical assortment of atmospheric monitoring activities to track dust devils and the amount of dust in the atmosphere, as well as several Navcam cloud movies. So far this dusty season the atmosphere over Gale Crater appears to be behaving much like it does most years, with no signs of imminent dust storms. It’s now been almost eight years (four Mars years) since the last time that

, so we’re keeping a close eye on the possibility of another one occurring this year.
