Limits of Life in the AtacamaLimits of Life in the Atacama
Robotic Investigation of Life in the Atacama Desert of Chile
Science Investigation• Seek life unambiguously• Understand habitat• Make relevant measurements
Technology Research• Over-the-horizon navigation• Efficient resource utilization• Autonomy with
self-awareness
Life in the Atacama 2004 Workshop 3 Carnegie Mellon
Detection of Sparse Microbes in Extreme EnvironmentsDetection of Sparse Microbes in Extreme Environments
Practical technology to enable the survey of large areas to yield evidence of life
• Explore the limits of microbe detection• Create fluorescent biomarkers for multispectral
detection of trace life• Develop biomarker correlation techniques for accuracy• Construct a fluorescence imaging instrument for
detecting sparse life in desert environments
Microscopic Fluorescence Intensity
Life in the Atacama 2004 Workshop 4 Carnegie Mellon
Science on the FlyScience on the Fly
Science autonomy during rover traverseResearch:Feature detection and segmentation (similar, dissimilar, and unique)Feature classification and evaluation (significance)Science-informed exploration
Focus on developing techniques and validating in ground-truthed rover experiments
Nominal TraverseScience on the Fly
Life in the Atacama 2004 Workshop 5 Carnegie Mellon
Atacama DesertAtacama Desert
Atacama Desert in northern Chile lies between the Pacific and the Andes
Driest desert on Earth
No measurable rain or snow in some regions but• Fog from the Pacific• Runoff from the Andes
Analogous to Mars
Arid, High UV, Soil Oxidants
Life in the Atacama 2004 Workshop 6 Carnegie Mellon
Interior DesertInterior Desert
Desert rises from Coastal Range (700m) to the Altiplano (4000m)Moisture blocked byPacific atmospheric pressure and the Andes
Most lifeless on Earth?Absolute desert evidenced by the absence of biogenic organic molecules?

Life in the Atacama 2004 Workshop 7 Carnegie Mellon
Coastal RangeCoastal Range
Parallels the Pacific coast
Camanchacas (salt fogs) occasionally penetrate inland through mountain range
Desiccation-tolerant organisms detected in microhabitats
10 - 40km
Life in the Atacama 2004 Workshop 8 Carnegie Mellon
Scientific InvestigationScientific Investigation
Biodiversity and distribution of habitats in Atacama subregions are not yet understood
Where does life survive and where does it not?
What factors govern the distribution?
Coastal Range Interior Desert
Life in the Atacama 2004 Workshop 9 Carnegie Mellon
Workshop ObjectivesWorkshop Objectives
• Review the current state of our research
• Examine preparations for the field season
• Understand current capabilities
• Finalize intentions for the field investigation
• Identify any outstanding issues
Life in the Atacama 2004 Workshop 10 Carnegie Mellon
Workshop PhilosophyWorkshop Philosophy
Find problems now rather than later
Expect discussion (and some confusion)
Identify actions and priorities
