  1. Dirty Ice or Icy Dirt? Water on Mars

  2. Hydrogen Gamma Ray Map

  3. Definitions of Soil Moisture Saturation UNDER-SATURATED Not enough water to fill all of the pore space of a given soil SATURATED Just the right amount of water to fill all of the pore space of a given soil OVER-SATURATED More water than can fit in the pore space of a given soil

  4. Hydrogen Gamma Ray Map Saturated? Saturated?

  5. North Arctic of Mars

  6. Experiment Objectives Design your own experiment! What is the maximum water weight % that typical dirt on Earth can hold?

  7. C A Dry Layer B Perma-frost Mellon, et al., 2004, Icarus 169, p 337. Ice Sheet Provided by Dante Lauretta, 2003. Water Estimates on Earth Guess the water weight % for each of the surface layers below. 0% Mellon, et al., 2004, Icarus 169, p 337. Saturated Permafrost Layer Over-saturated Ice Sheet Under-saturated Dry Layer

Water Estimates on Earth Approximate water weight % for each of the surface layers below. 0% 0-1% 10–30 % 100 % Saturated Permafrost Layer Over-saturated Ice Sheet Under-saturated Dry Layer
