Curiosity Update, sol 57: Digging in at Rocknest

JPL held a press briefing today to fill the public in on what the rover's been up to in the last week, and what to look forward to over the next couple of weeks. Curiosity is wrapping up sol 58, but hasn't returned that data to earth yet, so this blog covers events through sol 57. Just minutes after I first posted this, images from sol 58 started arriving on Earth.

Curiosity is now parked near the sand drift I showed at the end of my last update. The drift has a name: "Rocknest."

This sand drift, named Rocknest, became the target for Curiosity's first soil sampling. After taking this panorama on sol 55, Curiosity drove slightly to the right and then took a sharp left turn to prepare to position a front wheel on top of the nearest sand drift. Click through for the sol 56 view.

On the briefing today, mission manager Mike Watkins said that the engineers had requested that Curiosity be driven to a "nice sandbox" to play in for the first soil sample, and it appears that Rocknest satisfies that requirement. Here are the broad outlines of what to expect during the next couple of weeks of activity:

On sol 55, Curiosity rolled up to a sand drift called "Rocknest." On sol 56, the rover rolled its right front wheel onto the drift's peak, locked the other five wheels, then "scuffed" the drift by rotating the right from wheel 30 degrees. Then it backed up and surveyed the result.

In this animation Curiosity positions the robotic arm turret over undisturbed and then scuffed parts of the sand drift at Rocknest to photograph it with the Mars Hand Lens Imager.

Curiosity took these photos of a sand drift called "Rocknest" with its MAHLI microscopic imager on sols 56 and 58. The top row are two images taken of the drift from two distances on sol 56. The bottom row shows, on the left, the armored surface of the wind drift, and on the right, the interior of the drift after being scuffed by Curiosity's wheel.

There is a lot of work to be done, but it's work that'll be done while Curiosity is mostly parked. I asked if there were plans to take a big image mosaic from Rocknest, and the answer was yes. Hooray! There are also three videos planned -- three of the shaking of the three scooped soil samples, and two of sample deliveries.

Hello Having done a lot of off roading in the deserts of Southern California I know sand gets in EVERY thing. I see you sticking the instruments on the end of the arm very near the Martian sand. Is there any way to clean off dirt or sand that may get stuck on the instruments such as shaking it or raising it high over the rover to get it in the wind?

Sand sticking to everything is a fact of life on Mars as it is in the California desert. (I still have dust on my car from my trip to Edwards AFB 2 weeks ago.) In fact it's even worse on Mars as there's even more very fine dust. MAHLI has a dust cover; photo calibration targets have magnets that help steer dust off of some spots (Mars' dust is ferromagnetic); otherwise, they just cope! Google around for Spirit and Opportunity "deck panoramas" to see how those two rovers have been covered with more and less dust as "cleaning events" blow accumulated dust off. Curiosity will no doubt experience the same.
