Program:

1) "Ocean World Microhabitats 101" – Mike Malaska

Goal: Provide background and overview about Ocean World microhabitats.

  • What are microenvironments? Why should we care?
  • Where are they found?
  • How do they form?
  • Where would they be on other planets?
  • How have we detected them on Earth?
  • What are their scales?
  • What are implications for planetary exploration?

2) "Microbes of Extreme Environments" – Jeff Marlow

Goal: Provide context about the microbes and biosignatures that could inhabit microenvironments in extreme environments on Earth (Biology 101).

  • Microbiology of microbes that we would find in likely microenvironments (“micro” x 3!);
  • Microhabitat energy gradients;
  • Microhabitat microbe metabolisms;
  • Diversity of microbes we find here on Earth;
  • Implications for astrobiology of Ocean Worlds*
  • Implications for astrobiology of Mars permafrost and polar caps.

3) "Robotic acquisition techniques" – Kris Zacny

Goal: provide an introduction to different techniques to obtain a sample from ice or rock.

  • Small scale robotic sampling (drilling, grabbing) 101;
  • Drilling/getting samples in ice;
  • Drilling/getting samples in rocks;
  • Acquisition: getting from the drill (grabber) into the device;
  • How do we do this during planetary exploration?
  • What is state of the art for small scale sample acquisition?
  • What are limits and constraints? What are the big technical challenges to go really small to mm scale?

4) "Geochemistry, Biosignature and Life Detection Techniques" – Mary Beth Wilhelm

Goal: Describe the fundamentals of sample extraction, analysis, biosignatures, and instrumentation.

  • Extracting the sample: how do we get stuff out of ice or rock? (or cells)
  • Extraction techniques and instrumentation.
  • What is a “biosignature”?
  • What are typical biosignatures?
  • What kinds of instruments are used to identify biosignatures? (instrumentation 101)
  • What kinds of instruments can be used on really small sample volumes?
