Future Note:

• Sol 12 will be only 34m DSN.

Opening Issues at Start of Sol 10:

• Rover state of health is nominal, except for the failure of two non-critical temperature sensors (previously reported).
• Expect UHF localization at some point.

Sol 9 Summary:

• For Sol 9, the rover is nominal after its drive. The rover will collect some additional remote sensing observations, then perform a robotic arm touch and go with MI imagery, then a short approach (2.4 m) to Plainfield, with more Navcam and Pancam panoramas. Then some atmospheric observations.
• The IPS, Navcam and Pancam atmospheric observations mwereis-commanded. The IPS sky observations are in fact only observation of the calibration target, because mast actuation commands were not set correctly, due to operator changes to theme group activity. This error was not caught during the IST, nor during sequence approval. This was identified as a lesson learned.

Mission Success Criteria:

• 99.867% Pancam complete
• Estimate 27.33 meters total traverse
• One location
• Zero trenches
• For this test, NASA Headquarters establishes as a new location as:
• 20 meters wheel odometry (TBD)
• 2 out of 3 In Situ (not RAT)
• 1 of 2 Remote Sensing observations
• Sol 10 Downlink Assessment from Sol 9 Data:
• Sequence completed in 87 minutes, estimate of 90 minutes. Over shot target on traverse. Mast state of health is good.
• UHF location data received. 2.5 sigma landing within the 3 sigma error ellipse (west end of the landing ellipse).
• Missed the target, over shot Plainfield by about a target half-diameter. Got good MB data. MB reference data perfect. Did not get APXS. Did not get Mini-TES data. Touch and Go on UHF, but no error-outs in DTE.

Sol 10 SOWG Meeting:

• Approach sol to target Kaibab. Work volume unknown, so no robotic arm action.
• No changes in resource predicts. No status change in rover state of health. Now allowed to have 6 Mini-TES observations (up from 4). No Mini-TES data seen from last sol. Should request Mini-TES data re-transmit from last sol and perform a Mini-TES health check. APXS data received and identical to previous APXS data. No APXS data re-transmit.
• Pre-drive, Pancam and Navcam observations. Atmospheres group requests two Mini-TES (north/south) observations, plus Pancam and Navcam images up to high-elevation (full deployment on mast) with compression. Mineralogy group requests four Mini-TES observations. Geology group requests Pancam observations.
• Approach sol will involve a backup then a turn in place to way point, then a second approach to target. Long-term planning expecting the need for two approach sols to arrive at target. Post-drive Navcam and Hazcam imagery.

Post-IST Debrief:

• Hazard avoidance enabled. Drive index set to 2 (was 3 previously). First drive with index of 3 was about a factor of 4.5X conservative (so now estimating a factor of 3X conservative for driving in this terrain, although this terrain maybe more difficult than previous traverse terrain). Made first backup -1.5 meters (instead of -1.0 meters) to insure clear distance for turn in place from nearby rock. Made approach to final way-point 0.5 meters shorter than originally to reduce possible activation of hazard avoidance at or near ledge target. (I did not want to risk busting the headlights on the big approach rock!)
• Deleted Pancam panorama tier and chopped up remaining Pancam panorama to fit. Mini-TES data was confirmed down in UHF and looked ok, so Mini-TES re-transmit and Mini-TES checkout deleted. OK on all resource constraints (not busted on UHF).
• Note, error is SAP resource modeling found when driving backward. Needs to be corrected in SAP.

Mission Manager's Comments:

• Science team improving significantly in providing IST with complete or at least sufficiently detailed activities. IST process proceeding very smoothly as a result. Great science results. Outreach products identified and captioned by the science team.
• This stuff is getting fun!
