Steve Tegler reports about NAU alumna Kim Ward-Duong (BS 2010) Accordion Closed
“I came across an article in Radiations, the magazine of the Society of Physics Students (attached), describing my former undergraduate research student’s career track and her work with JWST and exoplanets. Kim made her first study of exoplanets here on campus with me in the early days of the Barry Lutz Telescope. Kim called out her NAU work on exoplanets in the article. She is now an assistant professor at Smith College. I love reading about the success of our students.”

“I remember Kim well — such a smart, capable, hard-working, and positive person. Great to see her continuing to succeed!”

Information from AST184L (“Life in the Universe — Lab”) from fall, 2022 Accordion Closed
GTAs Jessica Walsh and Ian Marrs report that there were approximately 30-45 students who participated in field trips to Meteor Crater, Sunset Crater, and the Grand Canyon.


There is no other university in the world that can visit these sites on day trips as part of a regular one credit lab class.
Ian writes:
Meteor Crater: Meteor Crater is relevant for the discussion of life in the universe because it affords us the opportunity to discuss meteor impact events as potential extinction events. While Meteor Crater is not thought to have significantly affected the biosphere (unlike the K-T impact) it is one of the most well-preserved impact craters on Earth and is therefore a useful field location to discuss impact events generally.
Sunset Crater: Sunset Crater and the surrounding volcanic fields are relevant for the discussion of life in the universe because they afford us the opportunity to discuss volcanism as a geologic process that mobilizes biologically relevant elements. Volcanoes are thought to have been critical to the development of life on Earth and the relatively recent lava flows at Sunset give the students a chance to understand the scale and context of volcanic eruptions.
Grand Canyon: The Grand Canyon is one of the best places on Earth to view a largely continuous exposure of the terrestrial geologic record.
This location is relevant for the discussion of life in the universe because it demonstrates to students how investigating geologic material can inform our understanding of the history of a planet in terms of biology, geology, meteorology, etc. Such investigations are how professional planetary scientists search for life on other planets and our understanding of the terrestrial geologic record helps us search for evidence of extraterrestrial life.

Helen Eifert participated in a NASA astronaut field geology training camp over winter break Accordion Closed
She writes:
“Over the last few years, I have been observing drying trends of saturated surfaces at various Mars-analogous sites in the deserts of the southwestern United States. Over the holiday break, I took this analog research of studying Mars on Earth a step further. I served as the crew geologist for Crew 271 at the Mars Desert Research Station near Hanksville, Utah. After discovering the research facility during a field trip for the DAPS planetary analogs class [taught by Christopher Edwards], I applied to participate in a two week astronaut simulation mission. Here, I acquired supplemental visible near infrared data of drying trends over multiple days in a mission simulated environment. This data will inform one of my dissertation chapters by providing a better understanding of the residence of water in clay mineral structures. As a bonus, I experienced the unique challenges of conducting science on Mars. This work will help to better understand thermophysical properties of geologic surfaces, Mars’ water history, and how we might detect moisture on Mars. All of which should help inform human missions to Mars in the future.”
