MARS: CURIOSITY u krateru GALE Vol II.

Ima kao puno lipi stvari ali ne smin reć...
Kažu da su upravo ovdje našli ono šta su tražili.
No, ne kažu o čemu se točno radi.

Puno prašine u zraku...

Sol 2870: Mast Camera (Mastcam)

Ovaj put je uzet uzorak gline i vršit će se takzvani mokri eksperiment.
Nakon 8 godina će to biti prvi od predviđena dva.
TRaže se ostaci eventualnog organskog odpada.

Ten sols ago was our final dress rehearsal and today’s plan is opening night for an experiment that has been anticipated since we landed just over 8 years ago. After our successful drilling of our “Mary Anning 3” hole, bits of rock powder are waiting in the drill assembly for delivery to SAM. In today’s plan, we’ll extend the arm over the SAM inlets (the paddle shaped doors seen in this recent image of the rover’s deck) and rotate the drill backwards so that we drop off six portions of powdered rock.
Once inside SAM, the powdered bits of rock will be soaked a very special solution called TMAH (see the link above for the full 11 syllable name). TMAH will help our science team identify what fragments of organic (carbon-bearing) materials are present in the clay-rich rock of Mary Anning. SAM contains only two small containers of TMAH and so we’ve been waiting for 8 years for just the right rock to drill to use this very precious expendable commodity. The wait is finally over and SAM will hopefully soon give us new insight into the chemistry of ancient Mars.

Our SAM TMAH experiment was successful! For those who don’t speak fluent rover team alphabet soup, as we described the other day, the SAM TMAH experiment is a long-awaited measurement by the Sample Analysis at Mars (SAM) instrument, which uses a special chemical called tetramethylammonium hydroxide (TMAH*) to help identify organic (carbon-bearing) molecules in the sample. SAM only has two containers of TMAH, so we wanted to be very sure that this was the right place to use one of them before running the experiment. The team is now eagerly awaiting results which will take us several months to fully interpret.
Meanwhile, rover operations continue with a busy weekend plan! ChemCam will do an atmospheric observation as the Trace Gas Orbiter flies overhead, followed by a long-distance image mosaic of a target called “Housedon Hill.” Navcam will then look toward the crater rim to measure the amount of dust in the atmosphere and will look for dust devils. Mastcam also has a dust-measuring observation of the sun.
On Sol 2881 SAM will clean out its gas chromatograph (GC) column (the tiny tube through which gases are passed to separate them based on their chemistry), and then on Sol 2882 we have a recurring set of Navcam and Mastcam observations of the target “Le Ceasnachadh” (I wish we had an abbreviation for that name!) at different times of day. These repeated observations allow us to better understand the “photometry” or light-scattering behavior of the rocks.
On Sol 2882 Mastcam will also observe the target “Upper Ollach” and the Mary Anning drill tailings to look for any changes, and will do a multispectral observation of the photometry target “Le Ceasnachadh”. ChemCam will also observe that target using passive spectroscopy (no laser, just reflected light).
We’ll wrap up with some early morning atmospheric observations on Sol 2883, measuring dust with Navcam and Mastcam and watching for clouds with Navcam.
*If you think tetramethylammonium hydroxide (TMAH) is a mouthful, another chemical that SAM carries is called N-methyl-N-(tert-butyldimethylsilyl)trifluoroacetamide! We call it MTBSTFA for short.

Dobro jutro" Ovdje Mars. 

Sprema se alat u ponedjeljak se ide natrag, prema gore.
