PROJECT OVERVIEW

• Create a network of autonomous motes capable of
  detecting life in extreme environments that
  analog Mars
• Understand our own origins and evolution, future
  prospects in space travel (i.e. if habitable
  environments are found)
• Contribute to Dr. Chris McKays research to find
  life in extreme environments
• Meet the goals of NASA

POTENTIAL PROBLEMS

• Determining what we are sensing and what
  biosensors to use
• Time / Keeping on schedule
• Buying supplies
• Interfacing sensors with motes (i.e. ensuring
  compatibility)
• Problems in design/Debugging
• Getting reply from companies and professors

14
TIMELINE FOR COMPLETION

• Completed Tasks
• Met with Edo Biagioni, PODS researcher
• Met with Daniel Jenkins, BE Professor
• Met with Vicky Hamilton, Mars Expert
• Been in contact with Chris McKay and his
  colleague, Dale Anderson
• Budget estimate for motes/Researching companies
• Casing test criteria

15

• Tasks Underway
• Complete schematic designs
• Purchase materials needed to build motes
• Understand how sensors and network works
• Consider deployment arrangements (ex.
  spring-loaded antenna and sensor)
• Power supply (possibly using batteries and solar
  panels)
• Finish all research
• Possible completion before April 1, 2006
• Finding bio-signs and how to detect it

16

• Tasks Pending
• Apply for funding for the summer semester
• Documentation
• Finding the perfect way to deploy chemicals
• Waiting for funding from the Astrobiology
  Department
• Getting replies from Professors and Companies
