• Thermal IR
• 37 spectra in total
• 11 compass points
• 7 pointed straight down (in the blind)
• 19 targeted
• Plus calibration spectra (3 each)
• Vis/Near-IR
• 15 spectra in total
• 12 compass points

• Vis/Near-IR only collected at beginning of test
  as backup for rovers spectrometer.

24 Samples from Rover Locales (above) plus
another 9 collected around Site C Samples will
be analyzed in same manner as discussed by Wyatt
for Site B samples.

Conclusions/Lessons Learned for 2005

• Targeted spectra tend to tell a lot more than
  compass points.
• Many spectra per locale easy Many locales per
  sol not so easy!
• Need dedicated ground-truthing/sample collecting
  person on-site in addition to instrument crew.
• Choose 2005 field sites EARLY!!!
