At the start of the semester, three teams of two students in AST 598: Planetary Analogs began the process of recreating a Mars rover mission from landing site selection through surface operations. The class was tasked with exploring the Granite Wash Mountains of western Arizona. Teams selected and advocated for landing regions based on
their safety and proximity to areas of interest. The class then voted on a single landing site, where each team then designed a rover traverse and data collection and sampling plan, emphasizing specific research questions and hypotheses to be investigated.

In mid-November, the class traveled to the Granite Wash Mountains and implemented their science plan for their “rovers.” Teams collected images and samples while following their pre-field strategies. Despite a few “anomalies” that restricted some of the data collected by the teams, each team successfully explored the region and made interesting observations regarding the local geology and ecology. Then like every good rover mission, the investigation ended with some homemade Mexican food and relaxing by a campfire.

Students Andy Lopez-Oquendo, Kathryn Turrentine, Schuyler Borges, Aaron Weintraub, and Adora Hall traveled to Navajo Bridge on Friday, October 25th-27th with the American Indian Mobile Educational Resources (AMIER) representative Mary Lara, and NAU representative Ed Anderson. The excursion began on Friday night when a Star Party was held on Navajo Bridge. Approximately 15 telescopes were set up on the bridge, including 6 from NAU and AMIER. Both locals and travelers alike stopped by the bridge to watch the sky and learn from the operators who discussed concepts of astronomy, physics, and planetary science for approximately 3 hours. The following day, the NAU Team set up 5 solar scopes, one of which with an H-alpha filter, to observe
solar flares and sunspots. Unfortunately, this time of year is currently marked by a minimum of stellar activity, and no sunspots were visible. But limb darkening, and small solar flares were visible and discussed with the public. UV Beads (small beads that change color in UV light due to electron excitation) were also set-up in a “DIY-UV-Detector-Lanyard-Making-Station”. That evening a second Star Party got underway. With less wind, slightly warmer temperatures, and just as many tourists (travelers from as far as Australia, Switzerland, and Italy) the second night proved even more successful than the first. With lots of small children and genuine interest in learning about astronomy, this weekend of outreach was fun for all.

outside of Page, this past week. The day begin with the in-class presentations to 1st, 2nd, 3rd, and 4th graders at the school. They discussed the phases of the moon, relative sizes of Earth, the Moon, and Mars, and even gave a UV Detector Bead demonstration, where the students made their own bracelets to learn about the Ultraviolet Light Rays emitted by the sun and the importance of protecting your skin from such rays. The day proceeded to a family night with over 15 separate, hands-on educational demonstrations to engage the young students. Some of these experiments included; playing with Oobleck (the incredibly-cool, non-newtonian fluid), dissolving Alka-Seltzer tablets in water to demonstrate sublimation, and the effervescent affects of various liquids on baking soda, and even a station to make slime out of glue and laundry starch. The day ended with a Star Party with four telescopes. Families with small children came for the hour and half viewing and discussing session of Lunar lava, binary stars, and Jupiter’s Galilean Moons. A successful education outreach expedition.

• Postdoctoral scholar Andrew McNeill and professor David Trilling were funded for “Mining the Transiting Exoplanet Survey Satellite (TESS) Data Archive for Asteroid Science.”
• Associate professor Mark Loeffler received a grant for his project, “The Role of Electron Irradiation in the Evolution of Planetary Icy Surfaces.” His proposal focuses on laboratory studies to understand erosion of icy extraterrestrial surfaces using electron irradiation. Robyn Meier, a recent graduate of the Applied Physics Program, contributed to the preliminary data used in the proposal.

GSA Fellowship is an honor that recognizes a sustained and distinguished record of contributions to the geosciences and the Geological Society of America through multiple avenues of academic achievements. She and graduate student Tony Maue also presented their research on Mars and Titan geomorphology in several talks.

Our proposal is “Between a rock and a frozen place: Cold-based glacial chemical alteration of volcanic bedrock as an analog for Mars.” The project will last three years and includes some funding for a graduate student. We will be collecting and analyzing sediments, rocks, and water from the summit of Mt. Kilimanjaro, Tanzania, to study chemical alteration at the base of cold-based glaciers (glaciers that are frozen to their beds). These measurements will better help us understand processes at work on the Red Planet!

will participate in the Remote, In Situ, and Synchrotron Studies for Science and Exploration 2 (RISE2) team, which was recently selected by NASA to collaborate on research into the intersection of space science and human space exploration as part of the Solar System Exploration Research Virtual Institute (SSERVI). The team will address key aspects of interpreting the surfaces of and samples from the Moon, Near Earth Asteroids (NEAs), Phobos and Deimos. Using a comprehensive approach to better understand the spectral data of samples and surfaces, develop protocols for safe and scientifically productive exploration of those surfaces, and in turn maximize the scientific value of samples, especially small, precious returned samples, RISE2 will produce a wealth of information and a team of well-trained next-generation scientists.
