MARS: CURIOSITY u krateru GALE

Čeka se da netko na UMSF "naštrika" ovu panoramu.

Sols 1303-1304: Driving Again

4 April 2016

The Sol 1301 drive halted after only 4.5 meters of progress, apparently due to a short in the RTG that caused a steering actuator fault.  This type of fault has occurred before, so we are planning a drive toward the northwest on Sol 1303.  Before the drive, lots of remote sensing science is planned, starting with a Right Mastcam mosaic of an outcrop toward the southwest dubbed "Rasthof."  Then ChemCam and Mastcam will observe bedrock targets "Tsondab," "Omingonde," and "Marble Koppie," and Mastcam will observe the Sun and the distant crater rim to measure the amount of dust in the atmosphere.  After the drive and the usual post-drive observations, on Sol 1304 ChemCam will shoot its laser at its titanium calibration target and Navcam will search for clouds again.

Sols 1305-1306: Deja vu

6 April 2016

Once again, the Sol 1303 drive stopped during wheel steering, apparently due to another short in the RTG.  While the power and mobility engineers investigate the fault and ways to respond to them, another drive will be attempted on Sol 1305.  The remote science observations made on Sol 1303 went well, so only one ChemCam/Mastcam observation is planned before the Sol 1305 drive, of a rock with interesting surface texture dubbed "Katwitwi."  Early on Sol 1306, Navcam, Mastcam and ChemCam will look for clouds and dust devils, and measure the amount of dust and various gasses in the atmosphere.  Later that sol, Mastcam will observe the Sun again and Navcam will acquire a panorama of the rover deck to look for changes in the distribution of dust and debris.  Overnight, CheMin will analyze and empty sample cell to improve instrument calibration.

Sols 1307-1308: Deja vu all over again

8 April 2016
On Sol 1305, the rover straightened its wheels in preparation for a drive, but then the fault that prevented driving earlier this week occurred again, and the vehicle did not move.  The engineers are preparing to send parameter changes that will eliminate mobility actuator sensitivity to the transient power spikes.

Fortunately, there are some rocks in front of the rover that are suitable for contact science, so the arm will be deployed on Sol 1307.  But first, ChemCam and Mastcam will examine a bedrock target named "Divundu" and rock target "Kapako," and Mastcam will acquire a full multispectral set of images of a distant bright ridge called "Ruacana."  Later that sol, MAHLI will take a couple images of Divundu before the DRT brushes dust off of the target.  MAHLI will then acquire a full suite of images of the brushed spot and smaller sets of images of a rock named "Gaio" and a bedrock target called "Lucira."  The APXS will be placed on Gaio for a couple of evening integrations, then on Divundu for a long overnight integration.

Early on the morning of Sol 1308, the Right Mastcam will acquire a mosaic of the north side of Aeolis Mons ("Mt. Sharp").  Later that morning, Navcam will search for clouds and dust devils, and Mastcam will image the crater rim to determine how much dust is in the air within Gale crater.  In the afternoon, the arm will be stowed before Mastcam acquires a multispectral observation of the Divundu brush spot before the rover attempts to drive again.  After taking the usual post-drive images, the rover will go to sleep and recharge its batteries in preparation for Monday's activities.  Only 2 sols are being planned today, to get the tactical schedule back in sync with "Mars time."

Već dva dana sređuju problem s aktuatorima (motorima) na kotačima.
Nakon sređivanja slijedi vremenska sinkronizacija s Marsom i tek onda pokret...
Meni se ovaj teren čini pregrub, ne vidm prolaza...Pratimo dalje.

Ovo otraga je nuklearna baterija, koja vozilu jamči 10 godišnje autonomno funkcioniranje.
Na koji način su zaštićena računala meni nije jasno. O tome se ne priča, barem ja nisam zaslijedio.

Sol 1309: Can't Catch a Break

11 April 2016

We just can’t catch a break lately! Curiosity is healthy but unfortunately the plan for the weekend was not transmitted to Mars due to a Deep Space Network outage. That means that the contact science that was planned for the weekend is lost, but the team decided that it was not important enough for us to delay driving. Today’s plan attempts to at least recover the remote sensing observations before we move on.
The Sol 1309 plan starts off with a continuation of the previous mosaic of the target “Rasthof” plus a multispectral observation of the target “Ruacana”. ChemCam then has a long distance RMI mosaic of some mesas to the west of the Peace Vallis fan, followed by an analysis of some dark cap rock at the target “Kapako”. Mastcam will document Kapako and finish up with a small mosaic of some interesting textures in a nearby part of the outcrop. After that, we have a short drive followed by standard post-drive imaging. In the afternoon, Mastcam and Navcam have several atmospheric observations and MARDI has an image of the terrain beneath the rover. Finally, in the early morning of Sol 1310 Mastcam has a mosaic of Mt. Sharp.

Pobliže viđeno, ovo se(po moje) otvara kao realna mogućnost prolaza do "doline". 
Stay tuned! ...
