4. Life in the Atacama 2005 Science/Technology Workshop 3NASA Ames Research Center / Carnegie Mellon Summary of Achievements (1) 41 locales listed; 24 unique locales investigated Total science traverses: Site B: ~ 6 km -- to be confirmed by E.T (all manual) Site C: ~ 23.5 km -- to be confirmed by E.T (13.9/12.5) Outstanding and first time demos for future missions (e.g., MSL and Sample Return): During the same sol (014): Successful return to a locale (040) of high-science value; Return ~150 m to LS after one week of investigation. The original plan was to allow 2 sols to get back accurately to a site.

5. Life in the Atacama 2005 Science/Technology Workshop 4NASA Ames Research Center / Carnegie Mellon Summary of Achievements (2) ~ Longest science traverse during ops: ~1.2 km; 3.3 km autonomous traverse (post-science ops); 0% autonomy at Site B; 83% autonomy at Site C after the camera were working; Mean autonomy at Site C: 59% Overall autonomy (Site B + Site C): 47%

11. Life in the Atacama 2005 Science/Technology Workshop 10NASA Ames Research Center / Carnegie Mellon Searching for Life: Where do we Stand? Uncertain diagnosis Increased confidence in diagnosis Increased level of confidence of RSTs

12. Life in the Atacama 2005 Science/Technology Workshop 11NASA Ames Research Center / Carnegie Mellon Pre-Mission Exploration Strategy Regional Mapping: Along a traverse from A to B, rover stops every determined n-meters, deploys a set number of instruments and always acquire same type of data Targeted Sampling: Thorough investigation of science targets of interest identified in the scene.

13. Life in the Atacama 2005 Science/Technology Workshop 12NASA Ames Research Center / Carnegie Mellon Post-Mission Exploration Strategy Adjustments (1) The demonstration of the ability to go back accurately to a distant site of science interest with the rover is opening new possibilities in terms of robotic astrobiology investigation strategy. For the 05’ campaign, we suggest a new strategy that will provide the best of the two “worlds” of the current targeted sampling and regional mapping: Tentative definitions: Regional Mapping Reconnaissance Survey Targeted Sampling Focused Investigation

15. Life in the Atacama 2005 Science/Technology Workshop 14NASA Ames Research Center / Carnegie Mellon Pros of the Reconnaissance Strategy: Maximize the use of rover mobility to cover long- range fast; Grasp quickly the main characteristics of an area; Allow time for the S.T to “digest” the information, thus; Decrease the chances of missing sites of high- science payoff; Still allows to perform regional mapping; Improve quality of samples and increase our ability to make educated conclusions Post-Mission Exploration Strategy Adjustments (3) -- ADDED VALUE Nathalie Cabrol:

16. Life in the Atacama 2005 Science/Technology Workshop 15NASA Ames Research Center / Carnegie Mellon Requirement: Robust demonstration of ability to go back to a specific site: Using way points, ground and satellite imagery; (this year demo) Develop technology that would allow the rover to follow its tracks back; Other methods? Post-Mission Exploration Strategy Adjustments (4)
