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).
This past summer, Professor John Moores completed a two-year term as the Science Advisor to the President of the Canadian Space Agency and became director of York University’s Earth and Space Science Program, which hosts 90 graduate students. He has recently (October 2024) published with co-author, Professor Jesse Rogerson, a popular science book titled, Daydreaming in the Solar System.
About the book, John writes, “Where Carl Sagan’s Cosmos sought to open a window onto the planets for a broad audience, we aim to pull the reader completely through the doorway. In science and story, we aim to immerse the reader in planetary environments and to communicate what it would feel like to actually be there on our neighbor worlds using the details we have learned from more than sixty two years of robotic space exploration. The book imagines an inclusive and optimistic view of the future of solar system planetary science. This vision is vividly explored with sixteen watercolor paintings and twenty six playful diagrams provided by illustrator, Michelle Parsons.
John continues, “In putting together this volume, I’ve been especially grateful for the broad knowledge base I developed as an LPL grad. I have appreciated the conversations with former classmates, other alumni and the entire extended LPL family over the past 16 years that have continued to deepen that understanding. I feel fortunate to be able to share our excitement and awe at exploring the solar system with the public.”
LPL alumnus Dr. Thomas Jones (1988) visited LPL and the University of Arizona in November to both receive and to bestow special awards. On November 12, Tom was presented with a special Professional Achievement Award from Arizona Alumni in recognition of his career prominence. In conjunction with the award presentation, Tom gave a lecture in support of his latest book, Space Shuttle Stories: Firsthand Astronaut Accounts from all 135 Missions. A reception and book signing followed. The following day, Tom held a roundtable with LPL graduate students and presented a lecture titled, Sky Walking: An LPL Astronaut’s Journey. At a ceremony that evening, Tom presented a 2024 Astronaut Scholar Award to U of A student Bryce Wilson.
Before becoming an astronaut Tom was a bomber pilot in the Air Force. Tom is a scientist, speaker, author, pilot, and veteran NASA astronaut. In more than eleven years with NASA, he flew on four Space Shuttle missions. On his last flight, he led three spacewalks to install the centerpiece of the International Space Station, the American Destiny laboratory. At LPL, his dissertation (1988) involved both telescopic and laboratory studies of asteroids and meteorites.
