Jupiter’s Icy Moon
NAU Department of Astronomy and Planetary Science students Becks Carmack and Patrick Tribbett are helping NASA prepare for the 2024 Europa Clipper Mission. Becks and Patrick are conducting research on the composition of Europa’s icy surface.

SOFIA is that 747 airplane with a hole in the side of it — for a telescope — for years.

She is shown in the photo below (she’s in the black shirt in the front row), as part of the mission crew for SOFIA’s last ever flight in September of this year. The mission has been canceled .. but Emily has landed on her feet. She recently started a new position as Senior Flight Operations Engineer at the Space Telescope Science Institute — the entity that operates the Hubble Space Telescope and James Webb Space Telescope.

A great story and a career arc that continues to rise!

The Soil of Mars
Department of Astronomy & Planetary Science PhD candidates Ari Koeppel and Helen Eifert are working with associate professor Christopher Edwards, to understand how moisture is retained on the martian planet.

Our department had a terrific showing there.

The following people were listed as first- or co-author on at least one presentation.

• Grad-students: Carmack, Engle, Humes, Lopez-Oquendo, McClure, McGraw, Raposa, Strauss, Thieberger, and Tribbett
• Postdocs: Oldroyd

This group represents 30 or more abstracts/presentations. Wow!

From 12 hours to 11.5 hours!

Our Cristina Thomas is head of the DART observations working group — in other words, the group that measured this result, which is the main result for the entire mission!

I haven’t even tried to follow all the press coverage of DART and Cristina, but there’s plenty out there for you read. I’ve seen Cristina appear in the New York Times at least 2-3 times over the past few weeks, and she tells me the paper with this main result in it is about to be submitted — fast work! Congratulations, Cristina, on all this success.

Exploring and Validating Exoplanet Atmospheric Retrievals with Solar System Analog Observations

Effects of phosphorus on partial melting of the Martian Mantle and compositions of the Martian Crust is about the effects of phosphorus on martian magmas and the implications regarding the mineralogy and composition of the upper-mantle and crust on Mars. Mars mantle contains 10 times more phosphorus than the terrestrial mantle, which has first orders implications regarding the composition/mineralogy of the interior of the two planets.

The role of assimilation and fractional crystallization in the evolution of the Mars crustdiscusses how crustal assimilation on Mars could have affected magma evolution, especially for felsic rocks analyzed by the Curiosity rover in Gale crater. It is the first time such process is modeled in martian conditions.

Catherine Clark, Lauren Biddle, and Erin Aadland. We are so proud of all of you!

Congratulations also to their advisors (by coincidence, all at Lowell Observatory): Gerard van Belle, Lisa Prato, and Phil Massey, respectively.

Finally, a special shout out to Ty Robinson (who served on all three committees!) and to Kathryn Neugent, who is an external member of Erin’s committee and is the first alum from our department to serve on one of our PhD committees (Kathryn received her MS from NAU in 2017, and participated in our REU program in 2009).

This document presents community-identified high priority research and investment areas for the coming decade. Congratulations to Chad Trujillo for his hard work as a member of the Small Solar System Bodies panel.

Fifteen members of our department presented their research. Congratulations and see you again in the fall!

Congratulations to all those students and their mentors.

Lunch Break Science: Infrared Mars: Seeing What Our Eyes Cannot

Every rock has a story to tell, from its composition, shape and even temperature. All these factors help uncover fascinating facts and sometimes unexpected stories from the past. So, what does Mars and its geology and temperature tell us about the big red planet and it’s habitability? Come find out!

Infrared cameras aboard satellites in orbit around Mars have collected an astoundingly complete record of martian surface temperatures spanning over five decades. So, how does this help us? Well, the physical makeup of certain rocks and sediments greatly affect how quickly surfaces can heat up or cool down, giving us invaluable insights into the geological make up of areas that are currently inaccessible. Studying these temperatures can make it possible to learn even more about past environmental processes on Mars and even if its climate was once conducive to life. In addition, studying Mars-like field sites here on Earth can help answer even more questions and bring us closer to the ultimate goal of Mars exploration!

In this fascinating lecture come learn about Mars and current NASA-funded work being done at Mars-like field sites on Earth, in Arizona, California, Hawaii and Iceland, in support of temperature interpretation.

A Dearth of Close-In Stellar Companions to M-dwarf TESS Objects of Interest

The challenge was to build a Titan lake sample return mission where it had to collect three samples from Ligeia Mare: 1) the atmosphere right above the lake, 2) the lake liquid, 2) solid material from either the shoreline or seafloor. Anna’s team decided to use a buoy+profiler design and the engineers built a system that would return 500 g of sample!! It was a great time and the team is already planning on doing yearly reunions!
