Sol 9
SOWG Documentarian Notes

 

Science Summary:

Preliminary analysis showed that the rover ended the traverse on sol 8 a few meters from Kaibab, very close to where the rover was commanded to stop.  Science analysis from the Mineralogy STG conducted during Sol 9 showed that the Oatland soil target measured by APXS, IPS, and MiniTES on Sol 7 was high in silica (quartz) and aluminum (feldspar) with very little to no carbon.  Stoney Point seems to be a mixture of quartz and phylosilicates but is distinct from Oatland; it contains much more clay and is more likely a diamagnetic smectite. 

MiniTES and IPS of Woodstock show it is consistent with a desert varnish and is most likely basalt since there is no sign of a quartz signature.  Rock morphology and a thick desert varnish suggests basalt.  The Mini-TES detected no carbonate in the "white" outcrop at Stoney Point.

Other science discussion can be found in the sol 10 summary, which contains the end of sol science debrief.

Tactical Operations:

The ongoing issue with mast stow has been solved.  The mast successfully stowed at the start of Sol 8 and that sequence executed normally.  For sol 9, the rover was healthy and cleared for all operations.  The poor MB and APXS data acquired on sol 7 have been attributed to a transmission problem, and the data will be retransmitted on Sol 9 and reevaluated.

For sol 9 operations, the general consensus was to approach Kaibab since Pancam shows it has crossbedding due to either fluvial or aeolian processes (see Science Debrief notes for Sol 8).  This approach will take advantage of the opportunity to visit Plainfield and perform a touch and go, which is a small rock at the limit of the allowed approach to Kaibab.  (Closer approach to Kaibab on this sol was precluded since we had only front hazcam data available.)  However, Plainfield was not within the IDD workspace at the end of the movement, so the suggested touch and go on sol 10 will not be done in order to continue toward to primary goal of approaching Kaibab. 

In addition to the approach on Kaibab, sol 9 also contained a variety of remote sensing observations designed to provide further information on the area surrounding Kaibab.  These observation included:

·        IPS observations (with supporting Navcam and Pancam images) of Plainfield, Paramour, the soil in front rover, and Platy 1

·        a monochrome Pancam wedge of the rover tracks to the rear of the rover for the Soil STG to derive soil physical properties

·        IDD deployment for the Soil STG of the CMI to a target of opportunity near Dumbell Lake called armtest4. 

·        sky observations with the IPS, MiniTES, and Pancam were commanded for the at Atmospheric STG to derive water vapor and dust characteristics.  However, the IPS was inadvertently pointed at the ground rather than the sky during these observations.

·        a color Pancam panorama 2 tiers high and 12 wedges wide centered on Paramour.  This pancam was acquired after the approach to Kaibab in order to provide better resolution for the panorama.  The panorama was meant to cover the upper portion of Kaibab to obtain further information on its stratigraphy.

·        Post approach remote sensing including front and rear hazcams and a 360deg Navcam to document the rover’s location as well as

The corrupted MB and APXS spectra from sol 7 were commanded for retransmit; the MB data looks good but the APXS data still looks poor.  The MB also performed an internal calibration, which indicated the instrument is healthy.

Some SOWG observations were removed or edited before uplink occurred due to a shortage of FIDO time.  This shortage was caused by the large pancam panorama acquired after approach.  The array pattern of some IPS measurements were reduced, the IPS support Pancam of Paramour was deleted since it will be covered in the end-of-approach pancam mosaic, and the Pancam wedges of the sky at 30deg and 80deg elevations were removed.
