The White House invited a group of five students plus one postdoc to have a special gathering with the Vice President (and the Secretary of Education, Miguel Cardona), where the students talked about their research, their interests, and their career goals.

David Trilling writes,

Support for this new facility comes from the university’s Elevating Excellence program, run by the Provost’s office and Laurie Dickson. Thanks to all of them for their outstanding support of our department.

Congratulations, Lisa!

Very cool! Congratulations, Dave!

This award fully funds a graduate student and postdoc at NAU for 3 years to carry out UAV-based activities. The award is for ~$500K direct costs. The NAU team will support the remote-sensing based characterization of the mine tailing sites under investigation. They will model the top-layer thermal inertia following methods developed by former grad student Ari Koeppel to determine the likelihood of material mobilization. While carrying out the thermophysical investigation is a primary aspect, characterizing the volume is the second goal NAU will support. They will precisely map the topography of the site using RTK (Real Time Knowledge) providing accuracy down to cm scales and finish by mapping the bottom layer boundary using a to be purchased ground penetrating radar on a UAV.

Arizona Space Summit

Edwards had a NASA PDAR (Planetary Science Data ARchiving program)funded with JPL which includes funding for a graduate student to derive near-global rock abundance on Mars from Thermal Emission Imaging System data at 100m/px. Total to NAU: $341K.

Circumbinary Accretion: From Binary Stars to Massive Binary Black Holes

This program investigates short- and long-term ecosystem dynamics within the Antarctic landscape and uses this cold and dry environment as a terrestrial endmember for understanding how the Earth is more broadly responding to climate change. The Planetary Exploration Lab here at NAU will be contributing remote sensing, spectroscopic, and GIS-based techniques to these investigations to help bridge the gap between the science that must be done in situ and the science that can be done remotely.

The program is entitled, An archival search for faint Trans-Neptunian Objects.

David Trilling is a co-investigator on this project, in which Ana and her team will analyze a decade’s worth of archival HST data for faint objects in the outer Solar System. David notes that “it’s pretty unusual for grad students to lead, let alone win, HST proposals, and I can’t think of another case where a student in their first year (when Ana wrote this proposal) had a selected proposal.”

Congratulations, Ana!

One is archival, and the other is new observations.
Congratulations, Phil!

for the project entitled, Building and Detecting Dust Enshrouded Planets. This is a 3 year program that will support an NAU grad student for two years. The total award is $476,091 and the sub-award to NAU is $178,196.

The Spatial Distribution of the Unidentified 2.07 \textmu m Absorption Feature on Europa and Implications for its Origin

She is presently a PhD student at Caltech.

These are independent graduate fellowships awarded in a very competitive process; FINESST is the Future Investigators in NASA Earth and Space Science and Technology. Congratulations also to their mentors — Mark Salvatore and Josh Emery, respectively — for this terrific result.

Typically NASA selects around 30 planetary science FINESST awards each year, and 2 of them this year are coming to NAU. By our records, NAU has had around 7 planetary science FINESST awards in the past four years, which is probably the highest, or one of the highest, of any university in the country.

They were collecting samples in support of Ian’s recently funded FINESST (see above) proposal entitled Using Trace Elements to Investigate the Role of Serpentinization in Jezero Crater Carbonate Formation. Serpentinization is an exothermic reaction where igneous rocks are altered in the presence of liquid water, making it an interesting process in the context of astrobiology. The team is currently busy preparing rock samples for spectral, mineralogical, and geochemical analyses.

NAU President Jose Luis Cruz Rivera on Twitter

“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!”

The Solar System Notification Alert Processing System (SNAPS): Design, Architecture, and First Data Release (SNAPShot1)

Mike Gowanlock is a faculty member of NAU’s School of Informatics, Computing, and Cyber Systems (SICCS) and an affiliate of DAPS; Daniel Kramer is a DAPS Alumnus (BS 2021, Astroinformatics, Astronomy Minor) and is currently a Master’s student at NAU/SICCS; Andrew McNeill is a former DAPS Postdoctoral Scholar and is currently at Lehigh University.

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.

Titled: “An Experimental Investigation of Space Weathering Processes on the Surface of Mercury,” 5he proposal is
$1.3 M for 3 years and brings about $100K to NAU.

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.”

and received a very enthusiastic thank you for bringing her energy, enthusiasm, and experience to our CAL colleagues.

Thank you, Lisa, and congratulations!
