On the morning of Dec. 3rd, LPL’s Vivian Carvajal, working on a joint asteroid survey project between Spacewatch and the Catalina Sky Survey (CSS) and using the 90" Bok telescope on Kitt Peak, discovered an imminent Earth impacting asteroid, which fell over Russia. This was the 11th such object to be found ahead of impact (6 out of 11 being found by CSS), the first impactor discovered by Vivian, by the joint project, and by a telescope at Kitt Peak. While all of these small objects burned up harmlessly in the atmosphere, these are fantastic tests of the entire asteroid early warning system of which CSS and Spacewatch are key players. Congratulations to Vivian and the entire CSS and Spacewatch teams!

Noah is majoring in Ecology & Evolutionary Biology with minors in Astrobiology, Marine Science, and Geosciences. When Noah chose his major he decided to add a minor that satisfied his interest in space science and would help answer his big questions like “Where did we come from?” and “Are we alone in the universe?” He also wanted to take advantage of being on campus with such great space science programs!
Noah really enjoyed taking PTYS 214: Life in the Cosmos with Dr. Dante Lauretta. He took this course in Fall 2023 when the OSIRIS-REx asteroid sample returned to Earth and was able to hear first-hand from Dr. Lauretta about the mission details and sample return. Dr. Lauretta’s enthusiasm inspired Noah to be more involved with astrobiology.
To support his passion for astrobiology, Noah began working at the Arizona Astrobiology Center, where he studies behavior in tardigrades. The project aims to measure any signals that may be produced by the tardigrades in association with the cryptobiosis behavior that makes them extremophiles. He is also completing a senior honors thesis project with Dr. Diane Thompson (Geosciences). The project uses corals to study paleoclimate patterns, specifically using manganese within the coral’s aragonite skeleton as a proxy for understanding wind patterns across the Pacific over time. Noah plans to apply to doctoral programs in evolutionary biology to research life on Earth, past and present, in order to understand macroevolutionary processes that can be applied to predicting how life would evolve on other worlds.
When he isn’t studying or pursuing his research, Noah enjoys spending time as vice-president of the campus Marine Awareness and Conversation Society, focusing on outreach to teach the community about marine biodiversity and ecology.
Thanks to everyone for supporting research, education, and outreach at LPL.

As our cover photo attests, a highlight of this semester was the planting of our second Moon Tree, a sweetgum grown from a seed that flew on the Artemis 1 mission around the Moon. Our original Moon Tree, a sycamore grown from a seed that flew aboard the Apollo 14 command module, has stood between the Kuiper building and Flandrau Science Center for about five decades. Since being planted, tens of thousands of students visiting Flandrau have gathered under the shade of the tree. Our own Dolores Hill is an expert on the Apollo Moon Trees (and reports that ours is the only remaining Arizona one). I asked her to submit LPL’s application for an Artemis tree and we are so grateful that she expertly led the entire process all the way through to planting.
To both protect our young sapling and to provide a spot to enjoy the respite it will offer future visitors to campus, we are aiming to locate a high quality bench adjacent to the tree, with a plaque denoting the significance of the tree. We would be grateful for donations to support the cost of the bench and its installation. Donations can be made online with a designation for the LPL Gift Account with a note in the text box that the donation is for the Moon Tree bench. Abraham Lincoln said that “He who plants a tree, plants a hope.” I think that is particularly appropriate for this tree as we look to the future of LPL’s continuing involvement in lunar research.
Dr. James Keane (2017) was awarded a NASA Early Career Achievement Medal in recognition of early career achievement in the geodynamics of the Moon and icy worlds, and for championing the Endurance rover science concept in the planetary decadal survey.
James is a planetary scientist at the NASA Jet Propulsion Laboratory. He studies the interactions between orbital dynamics, rotational dynamics, and geologic processes on rocky and icy worlds using theoretical models and the analysis of spacecraft-derived datasets. These techniques facilitate his investigation of the dynamics, structure, origin, and evolution of solar system bodies. James has experience with NASA missions including GRAIL and New Horizons.
Dr. Keane is also an accomplished science illustrator and communicator.

Dr. Jamie Molaro (2015) won both the 2024 Sagan Medal and the 2024 Neibur Early Career Award. The Sagan Medal, awarded by the Division for Planetary Sciences of the American Astronomical Society, recognizes outstanding communication by a planetary scientist to the public. The Neibur Award is given by NASA’s Solar System Exploration Research Virtual Institute to an investigator within 10 years of their Ph.D. who has made significant contributions to the exploration science communities.
Jamie is a Research Scientist with the Planetary Science Institute. She is a former participating scientist on NASA’s OSIRIS-REx mission and current member of the sample science team, as well as a co-investigator for Project ESPRESSO (Exploration Science Pathfinder Research for Enhancing Solar System Observations). She studies how heating and cooling breaks down rocks and boulders over time. Outreach and service are important parts of her career. She is the founder and the director of both The Art of Planetary Science, a public engagement effort to help people connect to science through art shows and workshops, and DAIS (Disabled for Accessibility In Space), a peer networking and support organization for Disabled scientists.
Dr. Ali Bramson (2018) is the recipient of the 2024 Greeley Award in Planetary Sciences from the American Geophysical Union. The award recognizes significant early-career contributions to the field of planetary science.
Ali is an Assistant Professor in the Dept. of Earth, Atmospheric, and Planetary Sciences at Purdue University. She studies the quantitative geomorphology of other planets, especially the physical processes related to ice and volatiles that affect the surfaces of solid bodies in our solar system. She uses spacecraft remote sensing observations and theoretical modeling, supplemented by occasional field work at terrestrial analog sites and experimental studies. Her research on Martian mid-latitude ice is helping to shape the future of in situ resource utilization and human exploration of Mars.
A prominent impact crater on Mars has been named in honor of LPL alumna, Dr. Nadine Barlow (1958–2020). For her dissertation at LPL, Nadine mapped and categorized every impact crater on Mars visible in Viking Orbiter imaging above a threshold size. In her subsequent career, she made many advances in our understanding of Mars from this dataset and from later enhancements. Nadine was a professor at Northern Arizona University, a noted leader in the field of Mars crater studies, and a dedicated teacher and mentor to students and colleagues. Nadine’s contributions to education and planetary science have also been recognized with a display at the Astronomy Discovery Center at Lowell Observatory (Flagstaff).
