"The lowdown on icy soil on Mars: The Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) on Phoenix" Abstract: MECA's microscope station, wet chemistry laboratory, and physical properties probe will perform the first analysis of the icy soil of the northern Martian plains in the summer of 2007. Combining optical and atomic force microscopes, the microscopy station will span the size range of airborne dust grains. Four identical chemistry laboratories carry their own water and chemicals to analyze martian mud and determine the soluble ions in the soil. The Thermal and Electrical Conductivity Probe (TECP) will measure permittivity, electrical conductivity, heat capacity, thermal conductivity, temperature, and humidity, and will collectively characterize the state of water in all phases in the ground. TECP also doubles as an atmospheric probe, measuring wind, air temperature, and relative humidity. March 6, 2008 3:30 pm - 4:30 pm 2245 SRB Auditoriaum |
