Sols 1586-1588: ChemCam sick

January 20, 2017 - Friday

MSL drove another 13 meters on Sol 1585, again placing the rover in a good position for contact science.  But the telemetry also showed that ChemCam had been marked "sick," so we will not be able to use ChemCam this weekend while the problem is diagnosed.  The weekend plan is still pretty full, though!  First, on Sol 1586, Right Mastcam will acquire small mosaics of nearby rocks named "Bell Brook," "Blind Brook," and "Beck Pond," then Left Mastcam will take another image of the rover deck to look for changes in the dust and sand on the deck.  The rover will rest until late that afternoon, when the illumination will be good for MAHLI imaging.  MAHLI will take a single image before the DRT is used to brush off a bedrock target dubbed "Belle Lake," then take a full suite of images (plus extra stereo images) of the brushed spot.  MAHLI will also acquire a full suite of images of another bedrock target called "Bluffer Pond" before the APXS is placed on the same target for a short integration.  Just before midnight, the APXS will be placed on Belle Lake for a longer integration.  On Sol 1587, the arm will be retracted and stowed to allow Mastcam to acquire a full multispectral set of images of Belle Lake.  Navcam will search for dust devils before the next drive.  In addition to the standard post-drive activities, the arm will be unstowed to allow Navcam to take stereo images of the new arm workspace.  MARDI will take images during twilight on Sols 1587 and 1588 to look for any changes due to winds.  Navcam will again search for dust devils on Sol 1588, and CheMin will perform some maintenance activities overnight.

Sol 1585: Examining "Jewell"

January 19, 2017 - Thursday

After a 31-meter drive on Sol 1584, MSL is in position for contact science on a block of bedrock in front of the rover.  So, as MAHLI/MARDI uplink lead today I focused on planning a full suite of MAHLI images of a target named "Jewell" that appears to expose sedimentary structures.  The Sol 1585 plan also includes ChemCam and Right Mastcam observations of Jewell, a single Right Mastcam image of another bedrock exposure dubbed "Bernard Mountain," and a Navcam dust devil survey.  The rover will then drive again and acquire images in the new location.  Later in the afternoon, Mastcam will measure the amount of dust in the atmosphere and Navcam will search again for dust devils.  After the usual MARDI twilight image is taken, ChemCam will perform some calibration activities at various temperatures.

Sol 1584: Touch and go at Frost Pond

January 18, 2017 - Wednesday

Sol 1583 Navcam Frost Pond

On Sol 1583 Curiosity drove 16 m, which set us up for touch-and-go contact science today.  I was the GKOP again, and it was a fun day of planning contact science and remote sensing.  The plan starts with a short APXS integration on the target “Frost Pond,” (seen in the middle of the above Navcam image) to investigate the chemistry of a typical Murray bedrock block.  Then we’ll take a full suite of MAHLI images on the same target.  Later in the plan we’ll acquire a ChemCam observation of “Frost Pond” for comparison, and we’ll also take a Mastcam image for documentation.  We’ll also acquire a small Mastcam mosaic of “Burnt Brook” to investigate some color variations, and a Navcam observation to search for dust devils.  After another drive, we’ll take post-drive imaging for targeting.  Later in the afternoon we’ll use Mastcam to monitor the movement of fines on the rover deck and take a systematic clast survey, and ChemCam will take another AEGIS observation.

Sols 1579-1582: A 4-sol plan

January 13, 2017 - Friday

After a 25-meter drive on Sol 1578, MSL is surrounded by more dark sand than usual, but there is enough rock exposed that we had a lot of science targets to choose from today.  Due to the US holiday on Monday, we are planning 4 sols today.  The first sol will include only REMS atmospheric observations while the rover recharges after the SAM methane measurement the night before, but the rest of the plan is packed!  Sol 1580 starts with ChemCam passive (no laser) measurements of the sky and calibration targets.  Then we'll use the laser to zap rock targets "Oak Bay" and "Rockport" and take Right Mastcam images of them.  Mastcam will also acquire a mosaic of bedrock exposures just west of the rover, measure dust in the atmosphere, and take another image of the rover deck.  Later that afternoon, ChemCam and Right Mastcam will observe disturbed sand at "Kennebec," an undisturbed ripple called "Spruce Top," and bedrock targets named "Traveler" and "Mars Hill."  Right Mastcam will also acquire a 3x1 mosaic of a more distant outcrop dubbed "Ogler Point." 

Sol 1581 is dominated by contact science, starting with full suite of MAHLI images of Mars Hill.  MAHLI will also take close-up images of nearby "Camera Hill" and acquire a 3-image mosaic of the layered outcrop target "Small Falls."  The APXS will be placed on Camera Hill for a short integration, then on Mars Hill for an overnight integration. 

On Sol 1582, Navcam will search for clouds and dust devils before the rover drives away.  After the drive, AEGIS will again be used to autonomously select a ChemCam target and acquire data, and MARDI will take another image during twilight.  Finally, the rover will get some well-earned rest overnight.

Sol 1578: Investigating sedimentary structures

January 12, 2017 - Thursday

Sol 1577 Navcam Megunticook

Curiosity had a successful drive of 45 m on Sol 1577.  We’re continuing to characterize the Murray formation by investigating changes in composition and sedimentary structures as we ascend Mt. Sharp.  Today’s plan provided another opportunity for touch and go contact science, starting with MAHLI imaging of the “Megunticook” outcrop.  This outcrop shows some interesting textures, as seen in the above Navcam image.  After MAHLI imaging of the outcrop, we’ll acquire ChemCam LIBS on the same target.  Then Mastcam will be used to document the outcrop and look for changes in texture, as well as to provide some stereo data for structural measurements.  After a ~35 m drive, Curiosity will take post-drive imaging for context and targeting.  The plan also includes an overnight SAM experiment to investigate methane in the atmosphere.

Sol 1577: Another touch and go

January 11, 2017 - Wednesday

MSL drove almost 30 meters on Sol 1576, stopping in a location with a nice exposure of bedrock in the arm workspace.  MAHLI's optics look clean, so we planned a full suite of MAHLI images and a short APXS integration on a bedrock target named "Mansell Mountain."  Fitting the remote sensing observations we wanted, along with the contact science and a ~46-meter drive, into the Sol 1577 plan was a challenge.  But the tactical team did a great job, working together to put together an excellent plan.  After the contact science is completed, ChemCam and Right Mastcam will observe an odd cobble called "Ames Knob" and a bedrock target dubbed "Day Mountain."  Left Mastcam will acquire a 2-image mosaic of the bedrock slab in front of the rover, and Right Mastcam will take an image of the Sol 1576 AEGIS target and a 4x1 mosaic of a layered exposure named "Appleton Ridge."  After the drive and the post-drive imaging needed to plan Sol 1578 activities, Navcam will acquire a panorama and search for dust devils and clouds.  It's been a busy day for me as SOWG Chair!

Sol 1576: Arm fault

January 10, 2017 - Tuesday

MSL planning started 2 hours later than usual today because the Sol 1575 data needed for planning weren't expected until almost 10 AM PST.  Unfortunately, the news was not good:  An arm fault prevented the MAHLI full suite from completing, leaving the camera close to the surface with its dust cover open.  The remote science and drive that were planned to follow were also precluded.  Fortunately, this fault has occurred before and is well understood, but recovering from the anomaly made for a rather hectic day for me as SOWG Chair!  The first order of business was to get MAHLI into a safe configuration, so the Sol 1576 plan starts with a single MAHLI image to look for evidence of dust on the exposed optics.  Front Hazcam images will be taken before and after MAHLI is retracted from the surface, then Right Mastcam will take a picture of MAHLI's optics, again to look for dust contamination.  Finally, the MAHLI dust cover will be closed and APXS placed on Dorr Mountain for a short integration.  The arm will then be stowed and Right Mastcam will acquire a 5x1 mosaic of a distant mesa named "Lobster Mountain."  ChemCam and Right Mastcam will observe Dorr Mountain and a bedrock target dubbed "Parkman Mountain," and Left Mastcam will take another image of the rover deck to monitor changes in the dust and sand on the deck.  Mastcam will also measure the amount of dust in the atmosphere before the drive is attempted again.  We don't expect as much data as usual in time for planning the next Sol, so we had to carefully prioritize the post-drive imaging, which includes another Navcam stereo pair of the arm workspace.  Later in the Sol, ChemCam will autonomously observe a target selected by the AEGIS software.  Finally, the rover will recharge overnight to get ready for more fun on Sol 1577.

Sol 1575: Investigating Dorr Mountain

January 09, 2017 - Monday

After a 25-meter drive on Sol 1574, MSL again has bedrock exposed in her arm workspace.  To balance desires to sample the composition of the rocks along the traverse and to make good progress toward the south, contact science and another drive are both planned for Sol 1575.  First, MAHLI will acquire a full suite of images of a knobbly bedrock target named "Dorr Mountain."  Then the arm will be stowed to allow ChemCam to observe the same target and for the Right Mastcam to acquire a 5x2 mosaic of the Dorr Mountain area.  Navcam will search for dust devils before the drive begins.  After the drive, the arm will be unstowed to allow Navcam stereo imaging of the arm workspace, in anticipation of another "touch and go" plan tomorrow.

Sols 1572-1574: New diagnostics

January 06, 2017 - Friday

MSL drove nearly 17 meters on Sol 1571, to a location with bedrock outcrops in the arm workspace.  So the weekend plan includes lots of arm work as well as remote observations.  On Sol 1572, MAHLI will take images of the REMS booms to diagnose recent problems with the wind sensors.  Some of the wind sensors on one boom have not functioned since landing, and sensors on the other boom have been acting up lately.  Later that afternoon, MAHLI will take a couple images of a yellow/red color boundary at "Greenstone" and a full suite of images of a yellow bedrock target named "Isle Au Haut."  The APXS will then be placed on Isle Au Haut for an overnight integration.  Early on the morning of Sol 1573, Navcam will search for clouds and Mastcam will measure the amount of dust in the air by imaging the Sun and the distant crater rim.  These dust measurements will be repeated at two other times of day later that sol.  Later that morning, ChemCam will acquire passive (no laser) observations of its calibration target.  Then the arm will go to work again to perform new diagnostic tests of the drill feed mechanism, to help us understand whether the drill feed stall is more sensitive to rotary-only or percussive drilling.  The test data acquired to date indicate an intermittent problem with the internal brake within the motor that feeds the drill forward and backward relative to the rest of the turret.  Fortunately, we are able to do everything except drilling while the investigation continues, but the team has decided not to try again to drill at Precipice, and to continue driving up the flank of Aeolis Mons ("Mount Sharp"). 

After the drill tests, ChemCam will perform some more calibration activities, and acquire LIBS data on Greenstone and a bedrock exposure called "Birch Harbor Mountain."  The Right Mastcam will then image these targets and bright vein targets dubbed "Tarrantine" and "Flying Mountain."  On Sol 1574, ChemCam and Right Mastcam will observe Isle Au Haut before the rover drives away.  After the drive, the arm will be unstowed and Navcam will take a stereo pair of images of the arm workspace to set us up for possible contact science on Sol 1575.  It will be another busy weekend for our intrepid rover!

Sol 1571: Leaving Old Soaker

January 05, 2017 - Thursday

The investigation of Old Soaker continues to go well, so we're planning to drive away on Sol 1571.  But first, ChemCam and Right Mastcam will observe darker bedrock patches named "Gilley Field" and "Fresh Meadow" and a dark clast called "North Bubble."  Mastcam will also acquire a multispectral set of images of a dark spherule dubbed "Greening Island" before the drive.  After the drive, the arm will be unstowed to allow Navcam and Left Mastcam to take pictures of the area in front of the rover to aid planning for this weekend.  Navcam will search for dust devils and clouds, then the rover will sleep overnight and recharge her batteries.
