ol 1604
Ovo nije bilo za očekivati...iznenađenje i za one koji su blizu ekipi.

sol 1604...
Položaj u blizini sol 1596...možda su u međuvremenu nešto primijetili iz podataka, pa zato ovo vraćanje. Nije prvi put da su se ovako vraćali , kako bi još jednom nešto detaljnije pogledali.

Vrlo intrigantno...Foto je kombinacija dva snimnka i različitih kamera. 
Područje je u blizini struktura na tlu, za koje se vjeruje da su nastale izbijanjem podzemnih voda 
i smrzavanjem na površini. Je li ovo što vidimo pijavica? Ili da se malo našalim - "vulkan" podzemne vode?

Sol 1604-1605: Toward Ireson Hill

10 February 2017

On Sol 1604 we wrapped up at the first stop of this second phase of the Bagnold Dune campaign. The plan started off, as usual for the dune campaign, with a pair of Mastcam images that were then repeated throughout the day to look for changes. ChemCam had an RMI of the target “Mapleton” and then Mastcam had a whole series of images of nearby sand formations. Once that was taken care of, we decided to drive back toward Ireson Hill so that we can take a closer look at some of the geology there. The drive was about 55 meters, followed by post-drive imaging.
In the 1605 plan, ChemCam’s laser is back in action with an analysis of the target “Carys Mills”. Mastcam will take a supporting image of the same target, as well as a small mosaic of the target “Calderwood”. We will then continue driving around the east side of Ireson hill toward our targets of interest, ending at a rock that may be part of the hill’s capping layer.

Sols 1606-1608: Studying Ireson Hill

10 February 2017

Our drive on Sol 1605 was successful, putting us in a good position for weekend science on the northeast side of Ireson Hill. The sol 1606 plan starts off with ChemCam observations of “Quimby,” which appears to be a piece of cap rock that has tumbled down from the top of the hill, and a bedrock target “Quoddy”. Mastcam will take an image to document the ChemCam dataset that was automatically collected at the end of the Sol 1605 drive, as well as a mosaic of an area called “Castine”. APXS will then do an overnight analysis on “Quoddy” and “Pogy”.
Sol 1607 is not too busy: the main activity is a short science block with atmospheric observations using Navcam, ChemCam, and Mastcam. Sol 1608 makes up for it though. It starts off with ChemCam of the targets “Cushing” and “Bucksport”. Mastcam will document those two targets and then do some multispectral observations of “Quoddy”, “Quimby”, and “Jemtland”. We will wrap up Sol 1608 with some workspace images and a MARDI image of the ground under the rover.

Sol 1609: Passagassawakeag and other challenges

13 February 2017
MSL drove a little over 9 meters on Sol 1608, to get the vehicle closer to Ireson Hill and the dark blocks that have rolled down from the top of the hill.  Two of these blocks are within reach of the arm, but both are challenging targets.  Even the name chosen for the dark block at the left side of the image above is difficult: "Passagassawakeag."  It's pointier that we would like for contact science, and the other dark block, dubbed "Perry" (at lower right in the image above), is close enough to the rover that there is a risk of collision with the arm.  Complicating the plan further, the best time to take MAHLI images of these targets is late in the afternoon, when they won't be shadowed by the arm.  But the last chance to send data to Earth in time to make them available for planning tomorrow is earlier in the afternoon, making it difficult to return all of the data needed to respond to a possible arm fault.  Therefore, we decided to acquire a single MAHLI image of Passagassawakeag from a safe distance of 5 cm before the critical communications opportunity, and send it in case the full suite of MAHLI images of Perry planned later in the afternoon is not successful.  We would then be better able to plan contact science on Perry tomorrow if necessary. 

The Sol 1609 plan starts with ChemCam and Right Mastcam observation of Passagassawakeag, a typical Murray bedrock exposure named "Spurwink," and a more distant dark block called "Wassataquoik" (another tongue-twister).  Then the Right Mastcam will acquire a 3x1 mosaic of the Perry area, single images of rocks near the top of the hill named "Gonic," "Kineo," and "Edmunds," followed by an 8x4-frame mosaic of the right side of the hill. Just before the MAHLI imaging of Perry, a full suite of MAHLI images, plus extra stereo frames, is planned on Spurwink.  After all of the MAHLI activities have been completed, the APXS will be placed on Perry for a pair of short integrations, then placed on Spurwink for an overnight integration.  Of course we are hoping that this complicated plan goes well!

Sol 1610: Finishing up at Ireson Hill

14 February 2017
The activities planned for Sol 1609 went well, and MAHLI focus data indicate that high-resolution images of Perry were successfully acquired.  So we're ready to drive away from Ireson Hill after some more remote sensing of the rocks in front of the rover.  The Sol 1610 plan starts with some more drill diagnostic tests, then the arm will be moved out of the way for remote sensing.  ChemCam and Right Mastcam will observe a bedrock exposure named "Fogelin" that shows subtle color variations, and Mastcam will acquire multispectral sets of images of yesterday's contact science targets Perry and Spurwink.  As more Sol 1609 data were returned during planning this morning, the Mastcam team noticed that the Right Mastcam image of Edmunds was blocked by the arm, so this activity will be repeated on Sol 1610 with the arm out of the way.  Mastcam will also measure dust in the atmosphere before the drive and standard post-drive imaging.  Later in the afternoon, Navcam will search for dust devils and clouds, and ChemCam will acquire some calibration data.  REMS will take a break from the usual environmental monitoring to update their flight software.
