Sol 1057-1058: Getting Ready to Drill Buckskin

Written by Ryan Anderson, Planetary Geologist at USGS Astrogeology Science Center

The "bump" over the weekend was successful, so we are right
where we want to be to attempt drilling at "Buckskin" in the "Lion" area. I was
on duty as ChemCam sPUL (science payload uplink lead) today, and it was a fun day to be on duty. Sometimes it
can be stressful trying to make sure that all the settings are correct and that
the instrument will be safe, but today everything was easy and I got to spend
more time on the fun stuff like choosing targets and their names!

The sol 1057 plan starts off with a Mastcam observation of
some disturbed soil at the target "Calamity" followed by ChemCam observations
of "Blind Gulch", "Sorrel Springs", and "Buffalo Basin". Mastcam also has a 4x5
stereo observation of the Lion area and some "tau" observations of the amount
of dust in the atmosphere. Once all that is done, we will brush a spot on "Buckskin",
observe it with MAHLI, and then place APXS on it for an overnight measurement
of its composition.

After a busy sol 1057, sol 1058 is pretty calm: it is mostly
dedicated to weather monitoring with REMS, plus MARDI will take an image of the
ground underneath us. By Ryan Anderson -Ryan is a planetary scientist at the USGS Astrogeology Science Center and a member of the ChemCam team on MSL. Dates of planned rover activities described in these reports are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.
