The drive on Sol 1378 went well, and Curiosity drove ~44 m to the south, bringing our total drive distance to more than 13.2 km.  We’re currently making our way through a gap in the Bagnold dunes (part of a dune is visible in the upper left of the drive direction Navcam frame, above).

Today’s two-sol plan includes targeted remote sensing, and contact science at a target named “Koes.”  We’ve been searching for a good place to do contact science on the Murray formation around here, and there won’t be enough power or time to fit contact science in the weekend plan, so it’s great to pick it up here.  The plan starts with ChemCam and Mastcam observations of “Koes” and “Onawa” to characterize the Murray formation.  Then we’ll use the DRT to brush off a fresh surface at “Koes,” followed by MAHLI imaging.  We’ll also use MAHLI to image the rover wheels, as part of our ongoing monitoring.  Then we’ll place APXS for an overnight integration on “Koes.”  We’ll also carry out a SAM preconditioning activity, which heats up a sample cup in preparation for solid sample analysis.  Curiosity will wake up early the next morning to acquire a Mastcam mosaic of “Baynes Mountain” to document the contact between the Murray and Stimson formations.  On Sol 1381, we’ll acquire another ChemCam observation of the Murray formation at “Khoabendus,” and we’ll use Mastcam to characterize veins at the target “Helgas.”  Then Navcam will be used to monitor the atmosphere and search for dust devils.

<![CDATA[Sol 1378-1379: Making up for lost distance]]> Tue, 21 Jun 2016 00:00:00 -0700

Over the weekend, the rover stopped after about 17 meters of the planned 65 meter drive. The rover is fine, the drive just tripped one of the (very conservative) limits on how the rover’s suspension was expected to behave, causing Curiosity to stop and check in with Earth. Since there is nothing jumping out at us as a contact science target where we stopped, in today’s plan we will try to make up for some of the lost distance from the weekend plan.

In the Sol 1378 plan, ChemCam has observations of some bedrock at the target “Tombua” and a rock named “Ai Ais”. Mastcam then will image the two ChemCam targets, as well as the Sol 1376 AEGIS target. Mastcam will also image some veins at a location called “Helgas”. After that, we will drive and collect some typical post-drive imaging.

On Sol 1379, we won’t have data down from Sol 1378 yet, so it is an untargeted plan. In the morning, ChemCam, NavCam, and Mastcam have some atmospheric observations. Then in the afternoon, ChemCam has some calibration observations, followed by a few more Mastcam atmospheric observations.

<![CDATA[Sols 1375-1377: Another busy weekend]]> Fri, 17 Jun 2016 00:00:00 -0700

The Sol 1373 drive completed successfully, moving the rover over 31 meters toward the south.  There's lots of bedrock exposed around the vehicle, but no flat patches large enough to brush in the arm workspace.  So MAHLI will take images of an unbrushed target called "Andara" before the APXS is placed on it for an overnight integration.  Before these arm activities on Sol 1375, ChemCam and the Right Mastcam will observe Andara and other bedrock targets "Okoloti," "Kalkfeld," and "Khorixas."  Mastcam will then acquire a stereo mosaic of a nice outcrop toward the southwest dubbed "Baynes Mountains" and a left-eye mosaic of another outcrop northwest of the rover.  The CheMin team requested another portion of the Oudam drill sample, which will be delivered late that afternoon.  After dark, MAHLI will image the CheMin inlet using its LEDs for illumination. 

Late in the morning of Sol 1376, APXS will integrate again on Andara to compare the quality of data acquired at different temperatures.  Then the arm will be stowed for a long (about 55 meters) drive, which will be followed by the usual post-drive imaging and another ChemCam AEGIS (autonomously-targeted) observation. 

On Sol 1377, the Left Mastcam will acquire a mosaic of the rover deck, to serve as a baseline for comparison with future images taken after passing the sand dunes along the path ahead.  Sand blown across the rover might remove some of the dust on the rover deck.  Finally, CheMin will analyze the new Oudam sample portion overnight.  It should be another busy weekend for MSL!

<![CDATA[Sols 1373-1374: No touch, just go!]]> Wed, 15 Jun 2016 00:00:00 -0700
The 32-meter Sol 1371 drive completed exactly as planned, giving the rover a good view of the path toward the south.  So another ~30-meter drive is planned for Sol 1373, after some remote science observations.  We had the option of using the DRT and taking MAHLI images of the brush spot before the drive, but the science team decided to acquire more remote science observations rather than brushing the Stimson Formation bedrock reachable by the arm.  Mastcam will image the path ahead through all spectral filters, then ChemCam and the Right Mastcam will observe Stimson bedrock targets "Sesfontein" and "Swartbooisdrif."  The Right Mastcam will image the ChemCam target that was autonomously selected by the AEGIS software on Sol 1371, and a Left Mastcam mosaic of a fracture zone west of the rover is planned.  On Sol 1374, AEGIS will be used to autonomously acquire another ChemCam observation and the Left Mastcam will take a 3x2 mosaic of the same area.

<![CDATA[Sols 1371-1372: Driving south]]> Mon, 13 Jun 2016 00:00:00 -0700 Sol 1369 Navcam

The weekend drive went well, and Curiosity drove ~ 32 m to the south.  This southward path will eventually take us through a gap in the active sand dunes that will be easier for Curiosity to traverse.  We’re planning another drive today, which will take us in the direction of the above Navcam image.

Today’s two-sol plan consists of several ChemCam and Mastcam observations of the Murray formation to assess variations in texture and chemistry.  We also planned a small Mastcam mosaic to document some nearby cross-stratification and nodules, and a small MAHLI mosaic of the target “Berg Aukas” before driving away.  After the drive, we’ll acquire our standard set of post-drive imaging for context and targeting.  The second sol includes a small untargeted science block, which we filled with a ChemCam autonomously selected target and a Mastcam observation to monitor the opacity of the atmosphere.

<![CDATA[Sols 1368-1370: On the road again]]> Fri, 10 Jun 2016 00:00:00 -0700 Sol 1366 Navcam

We received the engineering data that we needed to proceed with the final science activities at the Oudam drill site.  Today’s plan is focused on analyzing the pre-sieve dump pile and getting on the road again.

The three-sol plan starts by moving the arm out of the way so we can target the workspace.  First we’ll acquire a ChemCam passive observation on the pre-sieve dump pile, followed by several ChemCam and Mastcam observations of nearby veins.  Then we’ll use all of the Mastcam filters to study the DRT target “Aubures,” and we’ll acquire a Mastcam mosaic to document the local geology.  We’ll also target two areas to look for changes and the movement of fine-grained material.  Then we’ll move the arm back to the dump pile for MAHLI and APXS observations.  On the second sol we’ll use ChemCam to target the dump pile, and then we’ll drive away.  We’ll take our standard post-drive imaging, and an autonomously selected ChemCam target.  The third sol is devoted to ChemCam and Mastcam observations to monitor the chemistry and opacity of the atmosphere.

<![CDATA[Sols 1366-1367: Opportunistic contact science]]> Wed, 08 Jun 2016 00:00:00 -0700 Sol 1364 MAHLI Oudam hole

The day started off with some changes to the sol path due to some holes in the downlink.  Unfortunately some engineering camera and MAHLI images from Sol 1364 were not fully transmitted, so the team worked quickly to rearrange the intended activities this week.  Fortunately that also meant that we could add in some opportunistic DRT, MAHLI and APXS activities on Sol 1366.

The two-sol plan starts off with ChemCam and Mastcam observations of the Oudam drill hole and tailings, and the nearby target “Omulonga.” We’ll also acquire some Mastcam and Navcam observations to monitor the atmosphere.  In the afternoon of the first sol, we’ll use the DRT, MALHI and APXS to characterize the bedrock target “Aubures” to look for variations in texture and chemistry within the Murray formation.  On the second sol we’ll acquire a 360 degree Mastcam mosaic for geologic context, and a routine SAM electrical baseline test to monitor instrument health.  Hopefully the Navcam images will be retransmitted so we can continue with our drill site characterization activities later this week!

<![CDATA[Sols 1364-1365: Analyzing drill sample]]> Mon, 06 Jun 2016 00:00:00 -0700
The Oudam drill campaign continues to go well, with sample acquired and ready for analysis.  Planning is now restricted, so we are planning 2 sols today.  On Sol 1364, ChemCam will acquire passive spectra of the drill tailings and a LIBS raster of the wall of the drill hole.  Later that afternoon, the unsieved portion of the drill sample will be dumped on the ground and imaged by MAHLI from 25 cm to support future planning.  After dark, MAHLI will take pictures of the inside of the drill hole, the tailings, and the CheMin inlet using its LEDs for illumination.  The APXS will then be placed on the drill tailings for an overnight integration. 

Early on Sol 1365, the Right Mastcam will extend the mosaic of Hartmann's Valley, adding 22 images.  That afternoon, the APXS will be retracted and vibrated to clean it, then the arm will be moved out of the way for ChemCam and Mastcam observations of the drill tailings.  Navcam will search for clouds both near the horizon and at zenith.  Finally, CheMin will analyze the drill sample overnight.

<![CDATA[Sols 1361-1363: Drilling Oudam]]> Fri, 03 Jun 2016 00:00:00 -0700
The MSL Rover Planners have all the data they need to drill (no "mini-drill" required), so the plan for this weekend focuses on drilling into the Oudam bedrock target.  The full drill is scheduled for Sol 1361, followed by MAHLI and Mastcam images of the new hole.  The rover will then rest until Sol 1362, when the drill sample will be transferred to the scoop for Mastcam imaging and sieved.  A fine-grained (<0.15 mm) portion of the sample then will be dropped into CheMin for an overnight mineralogical analysis.  After the CheMin data are read out of the instrument on Sol 1363, Mastcam will take a multispectral set of images of the drill tailings and a Right Mastcam mosaic of an outcrop southeast of the rover.  In addition, ChemCam and Mastcam will observe a vein target named "Onganja" and a bedrock target dubbed "Ongeama," and Navcam will search for dust devils.  Another busy weekend for MSL!

<![CDATA[Sol 1360: Preparing to drill]]> Thu, 02 Jun 2016 00:00:00 -0700
Arm work continues to go well, so preparation for drilling and sample analysis is the focus of the Sol 1360 plan.  First, CheMin will dump the Lubango and Okoruso drill samples out of their cells.  Then ChemCam and Mastcam will observe a bright vein named "Charlottenfelder" and a bedrock target called "Chameis Bay" before arm activities resume.  MAHLI will take close-up images of the Oudam drill target and a single image of the "footprint" that APXS likely made on the Okoruso dump pile yesterday.  Overnight, CheMin will analyze an empty cell to provide a baseline measurement before receiving the new drill sample.  Early the next morning, before handover to the next plan, observations of the Sun and sky will measure dust in the atmosphere over the rover and search for clouds and dust devils.  The Right Mastcam will take a 10-image mosaic of the "Otjizonjati" outcrop northwest of the rover when it is well-illuminated by the morning sun.  Finally, the RMI will acquire a 5-image mosaic of part of Aeolis Mons (Mount Sharp) toward the south.

The remaining Okoruso drill sample was successfully dumped onto the ground on Sol 1358, so MSL is ready for a new drill sample.  In preparation, the Sol 1359 plan includes an arm preload test on "Oudam," the next drill target, and cleaning out CHIMRA with imaging to verify that everything is clean.  Before all the arm activities, ChemCam and Mastcam will observe the Okoruso dump pile and a bedrock target named "Otjosondu."  The Left Mastcam will also acquire a 5x2 mosaic of the "Fraktuur Dorp" area and extend the "Hartmann's Valley" mosaic.  Late in the afternoon, when lighting will be better, MAHLI will acquire images of bedrock target "Onguati" and a full suite of images of the dump pile.  The APXS will then be placed on the dump pile for an overnight integration.  The tactical team did a great job of picking targets and preparing command sequences, so it was an easy day for me as SOWG Chair.

<![CDATA[Sol 1358: A Simple Plan]]> Tue, 31 May 2016 00:00:00 -0700 ChemCam view of Mt Sharp taken at the same time as a HiRISE image of the same area as seen from space.

Our activities over the weekend went well, and after a couple of complicated multi-sol plans we get to do a nice simple one-sol plan today! The Sol 1358 plan starts with ChemCam observations of the targets “Otiiha”, “Otjihase”, “Otjikoto”, and “Otjimbingwe” to assess variations in the bedrock chemistry. Mastcam will document those targets, and then we will dump out our remaining Okoruso sample. APXS then has an overnight observation of the target “Oudam”.

I was on downlink for ChemCam today, so while everyone was putting together the plan for today, I was busy analyzing the tons of great data that we got down over the long weekend!

<![CDATA[Sol 1355-1357: Coordinating with MRO]]> Fri, 27 May 2016 00:00:00 -0700

Our drive went well and Curiosity is now sitting on a nice patch of the Murray formation, putting us in a good position for a very busy holiday weekend! On Sol 1355, ChemCam has observations of the targets “Auchas”, “Kaisosi”, “Inamagando”, and “Horingbaai”. Mastcam will document those targets and then do some multispectral observations of the targets “Kunjas” and “Navachab”, plus a mosaic of the contact between the Murray and Stimson units. Navcam will round out the science block with some atmospheric observations.

Sol 1356 was an unusual one, with a bunch of small science blocks spread throughout the day. These were to enable a series of measurements leading up to a coordinated set of observations in the afternoon between the instruments on the rover on the Mars Reconnaissance Orbiter. (Yes, this means a new HiRISE image of Curiosity is coming soon!)

First thing in the morning on Sol 1356, Mastcam and Navcam have a photometry observation. This is repeated a few hours later along with a multispectral Mastcam observation of the target “Inamagando”. A few hours later, the photometry observation is repeated again (the idea is to see how the brightness changes as the sun angle changes) and ChemCam has a passive sky observation. Finally, there is another photometry observation, a Mastcam “sky survey” observation, and Mastcam “sky flats”. These are followed by a long-distance ChemCam RMI image that I managed to squeeze into the plan. I am hoping that the similar time of day (and therefore similar lighting) will make it easier to compare the HiRISE and RMI images. After the RMI, Sol 1356 will wrap up with one final photometry observation.

On Sol 1357 we will drive again, followed by standard post-drive imaging. This plan will take us through the long weekend, so our next planning day will be on Tuesday.

<![CDATA[Sols 1353-1354: Clear sailing]]> Thu, 26 May 2016 00:00:00 -0700
The Sol 1352 post-drive imaging shows that, while there are sandy ripples ahead, there are enough rocky patches that the rover should not have any problem driving toward the southwest.  This is what we were hoping, so we are planning to drive in that direction on Sol 1353.  But first, Mastcam will acquire stereo mosaics of the Murray-Stimson contact and a couple areas toward the west with nodular features.  After the drive, ChemCam will again autonomously measure the chemistry of a target selected by the AEGIS software. 

To get a head start on planning for the Memorial Day holiday weekend, two sols are being planned today.  We expect to receive the Sol 1352 data needed for planning the rest of the weekend tomorrow morning.  The Sol 1353 activities cannot be precisely targeted, so Navcam will look for clouds and Mastcam will measure the amount of dust in the atmosphere at various times that sol.  In addition, ChemCam will perform a routine calibration activity.  Once again it was an easy day for me as MAHLI/MARDI uplink lead, with only the usual MARDI twilight image to plan.

We'd like to keep driving toward the southwest, but can't see all of the terrain ahead from our current location.  So the Sol 1352 plan includes a short drive to give us a better view.  Before the rover moves, Mastcam will acquire a large stereo mosaic of the "Breckhorn" ridge in front of the vehicle and extend the left Mastcam mosaic of the "Fracture Town" area to the west.  ChemCam and Mastcam will also observe a rock called "Tsongoari."  After the drive, images are planned that will hopefully allow the tactical team to find a safe path ahead.  It was an easy day for me as MAHLI/MARDI uplink lead today, with only an end-of-drive MAHLI image and a MARDI twilight image.
