MARS: CURIOSITY u krateru GALE Vol II.

U smjeru vožnje...nimalo prijatan teren  za već otećene kotače.

Sols 1482-1483: Another touch and go

5 October 2016
MSL drove another 35 meters on Sol 1480, stopping at a location with a layered bedrock exposure right in front of the rover.  So the tactical planning team decided to take advantage of the touch and go option again.  MAHLI will take pictures of the layered target "Cassongue" and of the rover wheels before the arm is stowed in preparation for another drive on Sol 1482.  ChemCam and Mastcam will observe bedrock targets named "Coutada," "Cuangar," and "Cacuso," and the Right Mastcam will acquire mosaics of more distant targets dubbed "Lucusse" and "Lumeje."  The Left Mastcam will be used to image the wheels on the right side of the rover and to extend the coverage of the terrain in the direction we plan to drive. 

Because we don't expect to receive as much data as usual in time for planning on Friday, the volume and downlink priorities of post-drive imaging data had to be carefully scrubbed.  On Sol 1483, AEGIS will again be used to autonomously select a target for a ChemCam observation.  Navcam will search for clouds and Mastcam will take an image of the rover deck to look for changes in the distribution of dust and other debris.  Finally, the Right Mastcam will take a look toward the east and acquire a 5-image mosaic of the Murray Buttes in the distance.

Nešto o ovom blatnom "kamenju".
Radi se o  sedimentima, koji su se nalagali zilijunima godina. Ovo bijelo su talogi
 pronicujuće vode i kako kažu u NASA_i radi se o gipsu. Gips u ovom trenutku služi
kao željezna armatura u betonu-obuhvaća neki volumen blata (kemijski povezanog
i smrznutog), koje je koliko-toliko postojano, sve dok na jednom kraju ne popusti
gipsna armatura). Nakon toga se otvara kamen i raspada u prah...Očigledno je gips 
rezidentniji (postojaniji) na strahovite toplotne promjene, plus na sunčevo bombardiranje ...
Ovakvih primjera imamo i na Zemlji..

Planirani putevi za prelazak "dark dunes":
Od rute "1"(bijela linija) se očigledno odustalo. Ruta "2" (plava linija) je najbližno ono što se trenutno ostvaruje.
Na samom prelasku "dark dunes" se praktično udružuje sa "3" (zelena linija), što znači da tamo nema drugog izbora. 
U slučaju problema bi to značilo odustajanje od smjera i eventualni povratak planiranoj ruti !1".

Na kompozit fotografiji piše "Left NavCam"...lapsus calami, naravno. Radi se o Left MastCam.

Sols 1484-1486: Dropping off samples to SAM

7 October 2016
The MSL rover made another 40 meters of progress up the flank of Mt. Sharp on Sol 1482, and there were multiple bedrock blocks within reach of the arm for the weekend plan.  A smooth patch on a nearby block was selected for DRT brushing and associated imaging, and named "Serowe."  The Sol 1484 plan also includes two dropoffs of the latest drill sample to SAM, a full suite of MAHLI images and short APXS measurement of "Tobane" on another bedrock block.  That evening, the APXS will be placed on Serowe for an overnight integration.  Early the next morning, Navcam will search for clouds and dust devils, and Mastcam will measure the amount of dust in the atmosphere.  Later on Sol 1485, the arm will be stowed to allow ChemCam and Mastcam to observe Serowe and Tobane, and the Right Mastcam will acquire a mosaic of laminated bedrock dubbed "Masunga."  Then another drive is planned, along with the usual post-drive imaging.  AEGIS will be used to select a ChemCam target on Sol 1486, and Mastcam will again measure dust in the atmosphere.  Finally, MSL will sleep in preparation for Monday's activities.
