Assistant Professor Dani Mendoza DellaGiustina is the invited Fred Kavli Plenary Lecturer at the American Astronomical Society’s 247th meeting in Phoenix, Arizona in January 2026. Each year the AAS Vice Presidents name a special invited lecturer to kick off each AAS meeting with a presentation on recent research of great importance.

Dr. DellaGiustina was invited to deliver the lecture in her role as Deputy Principal Investigator of the OSIRIS-REx sample-return mission. The mission team is commended “for providing groundbreaking insights into the origins of the Earth and other solar system bodies via the significant achievement of successful sample return from the near-Earth asteroid 101955 Bennu.”

Dr. James Keane (2017) was awarded the The Harold C. Urey Prize, which recognizes and encourages outstanding achievements in planetary science by an early-career scientist. He distinguished himself with his broad and impactful research portfolio studying the geophysics of worlds across the Solar System, including the Moon, Io, Arrokoth, Pluto, and Enceladus.

Dr. Keane is also an accomplished science illustrator and communicator who has improved the accessibility of planetary science to not only the scientific community, but the general public. He has a record of community service and outreach serving as a member of DPS, AAS Committee on the Status of Women, and multiple other scientific organizations and groups. James is a mentor to graduate students at Caltech, Purdue, and University of Arizona.

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, Juno, and New Horizons.

LPL alumna Dr. Faith Vilas (1984) was awarded the 2025 Gerard P. Kuiper Prize by the Division for Planetary Sciences of the American Astronomical Society. This prize recognizes and honors outstanding contributors to planetary science. Past recipients include geologist Eugene Shoemaker, who co-discovered comet Shoemaker-Levy 9, and astronomer and science communicator Carl Sagan. University of Arizona Professor Emeritus William Hubbard and Regents Professor Emeritus Donald Hunten have also received this prestigious award.

The DPS commends Vilas’ distinguished career of groundbreaking research and wide-anging innovations. She has made outstanding contributions to planetary science across a range of diverse topics. She has pioneered remote sensing of the Solar System, pushing capabilities through instrument design and expert observations of a variety of targets. Vilas designed the coronagraph used to acquire the first image of a circumstellar disk around another star and made the first asteroid survey using a CCD spectrograph, an instrument for measuring the intensity of light at different wavelengths. She made pioneering observations of aqueous alteration on primitive asteroids, the mineralogy of Mercury and hydration on the Moon.

The DPS presented Vilas with her award at the 2025 EPSC-DPS meeting, held in Helsinki, Finland on Sept. 11, where she gave the keynote speech.

“I’ve been in planetary sciences for 50 years. When I began, humankind’s first space probes were passing planets in our Solar System for the first time,” she said. “Now we study samples of material returned from the surfaces of asteroids to the Earth and determine the compositions of atmospheres of planets around other stars. Our scientific growth has been extraordinary.”

Her service to and leadership of the community have been extraordinary, according to the DPS commendation, including her roles as Program Director for Planetary Astronomy at the National Science Foundation; Chief Scientist of the NASA Planetary Data System; inaugural NASA Small Bodies Assessment Group Chair; Chair of the American Astronomical Society Division for Planetary Sciences; NASA Discovery Program Scientist; and Vice-Chair and Chair of the Detection and Characterization Sub-Committee on National Academies’ 2010 study on near-Earth object detection, characterization, mitigation. She was the Director of the Multiple Mirror Telescope, or MMT, observatory from 2005-2010 and has been involved in missions such as MESSENGER – short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging – at Mercury and Hayabusa at the asteroid Itokawa. Furthermore, she currently serves as the inaugural Editor of the AAS Planetary Science Journal. The impact of exceptional planetary science contributions enabled by Vilas’ work in these areas cannot be overstated.

The DPS, founded in 1968, is the largest special-interest Division of the AAS. The AAS, established in 1899, is the major organization of professional astronomers in North America.
