Sol 1140: Zapping the drill hole wall

Posted by Ryan Anderson

The ChemCam RMI images of the drill hole planned yesterday were successfully acquired and received, and were used today to plan 2 parallel LIBS rasters down the hole.  The additional LIBS raster should be useful in measuring variations in chemistry among individual sand grains and in detecting thin veins.  ChemCam and Mastcam will also observe a target dubbed “Marshall” to see whether silica enrichment extends along other fractures near the rover.  Finally the SAM methane experiment that was deferred due to an uplink problem last week is scheduled overnight between Sols 1140 and 1141.  This experiment requires a significant amount of power, which will limit the activities that can be planned tomorrow.

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.
