1 2. MENTOR DESCRIPTIONS In the Phoenix Student Interns Program, scientists from the Phoenix Science Team act as mentors to the students and teachers, involving them in research and projects associated with the Phoenix Mars Lander Mission. Please read the mentor descriptions below to determine the team to which you would like to apply. Geographic Proximity Required means that you and your students must be close enough to the mentor s institution to be willing and able to travel to the site at least twice a month to work in a lab, meet with the mentors and colleagues, and prepare for the mission. This is due to the specialized equipment or activities required by the mentors work. Open Nationwide means that you and your students can be located anywhere in the United States, including U.S. possessions and schools operated by the U.S. for the children of American personnel overseas. The mentors work does not require specialized/unattainable equipment. Work with such scientists would be accomplished across distance (phone, , Internet). ***Note: U.S. Citizenship is required of all participants (teacher and students).*** GEOGRAPHIC PROXIMITY REQUIRED (You must be close enough to the mentor s institution to travel to the site ate least twice a month) Name Location Deborah Bass Jet Propulsion Lab, Pasadena, CA Diana Blaney Jet Propulsion Lab, Pasadena, CA William Boynton Univ. of Arizona, Tucson, AZ Mike Hecht Jet Propulsion Lab, Pasadena, CA John Hoffman University of Texas, Dallas, TX Sam Kounaves Tufts Univ., Medford, MA Doug Ming NASA JSC, Houston, TX Nilton Renno Peter Smith Carol Stoker Leslie Tamppari Ray Arvidson Dick Morris Univ. of Michigan, Ann Arbor, MI Univ. of Arizona, Tucson, AZ NASA ARC, Mountain View, CA Jet Propulsion Lab, Pasadena, CA OPEN NATIONWIDE Washington University, St. Louis, MO NASA JSC, Houston, TX Ray Arvidson Ray Arvidson is a Professor of Earth and Planetary Sciences at Washington University in St. Louis, MO.

He is a Co-Investigator (TEGA Lead, Geochemistry) of the Phoenix Mars Mission. In this role, Boynton will operate the TEGA instrument on Mars, will calibrate the engineering model of TEGA, and will analyze the data after they come back from Mars. The teacher and students chosen to work with him will assist with the laboratory calibration of the instrument and with the data reduction process with a goal of generating reports and publications on the results of the mission. Mike Hecht Mike Hecht is a physicist at NASA's Jet Propulsion Laboratory in Pasadena, CA. He is a Co-Investigator (MECA Lead, Material Properties) of the Phoenix Mars Mission. In this role, Hecht will have overall responsibility for the MECA instrument suite and will use the MECA data to help understand the distribution and state of water, ice, and water vapor; water-soluble chemicals; and the physical characteristics of soil particles. The

3 teacher and students chosen to work with him will compare mission data with measurements from laboratory specimens with a goal of simulating martian soil on Earth. John Hoffman John Hoffman is a professor in the Physics Department at the University of Texas at Dallas, in Richardson, TX. He is a Co-Investigator on the TEGA experiment of the Phoenix Mars Mission. In this role, Hoffman will be working with the data to interpret the mass spectra to determine the composition and abundances of the gases observed in the effluents from the soil/ice samples scooped up from the trench that are heated in the TEGA ovens. The teacher and students chosen to work with him will become familiar with the mass spectrometer and its operating characteristics, learn how to extract mass and abundance data from the spectra, learn how to plot the data and interpret the results with a goal of verifying the existence of water in the samples, identifying any gases dissolved in the water, and determining the composition of minerals and atmospheric constituents. Isotopic ratios of the principal elements and the noble gasses will also be determined. Sam Kounaves Sam Kounaves is a Professor of Chemistry at Tufts University in Medford, MA. He is a Co-Investigator (Wet Chemistry Lab Lead, Chemical Analysis) of the Phoenix Mars Mission.
