  Measuring Thermal and Electrical Properties on Mars
Gaylon Campbell
Decagon Devices, Inc

A Decagon instrument, TECP (Thermal and Electrical Conductivity Probe), was a part of NASA's Phoenix Scout Lander which landed on Mars May 25, 2008. The probe was inserted by a robot arm into the Martian surface to measure thermal conductivity, heat capacity, electrical conductivity, and dielectric constant of the soil. In addition to these measurements, the instrument measured wind speed and atmospheric vapor pressure. The purpose of the measurements was to provide the data needed for Martian energy balance models, and to collect data which can be used to assess the state of water and the hydraulic properties of the regolith. The seminar will include background on thermal and hydraulic properties of frozen soil, and describe TECP design and performance.
