1. Spectral Observations and Ground-truthing at Site C Life in the Atacama 2005 Science & Technology Workshop January 6-7, 2005 Jeff Moersch U. Tennessee

2. Life in the Atacama 2005 Science/Technology Workshop 1NASA Ames Research Center / Carnegie Mellon Summary of Spectra Acquired at Site C 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” 3 targeted Vis/Near-IR only collected at beginning of test as backup for rover’s spectrometer.

7. Life in the Atacama 2005 Science/Technology Workshop 6NASA Ames Research Center / Carnegie Mellon 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!!!
