SSERVI Award Winners 2022

Recognizing that science and exploration go hand in hand, NASA created SSERVI in 2013 to advance human exploration of the Moon and other solar system destinations. The SSERVI Awards recognize outstanding achievement in exploration science and recipients have each made unique contributions to NASA’s human exploration efforts. SSERVI Award winners are nominated by their academic peers and are selected by a committee based at SSERVI’s central office. The awards will be presented along with invited lectures from the recipients at the 2022 NASA Exploration Science Forum (NESF) taking place July 19-21.

It is our great pleasure to announce this year’s SSERVI award winners. Each is exceptionally deserving, and each is an outstanding member of our community, providing both exceptional science and strong leadership.


The 2022 Susan Mahan Niebur Early Career Award is an annual award given to early career scientists who have made significant contributions to the science or exploration communities. Recipients of the Susan M. Niebur Early Career Award are researchers who are no more than ten years from receiving their PhD, who have shown excellence in their field and demonstrated meaningful contributions to the science or exploration communities. This year the award is presented to Drs. Kelsey Young and Orenthal James “O.J.” Tucker.

Kelsey Young is a Research Space Scientist at NASA Goddard Space Flight Center focused on the integration of science into human exploration and addressing major strategic knowledge gaps in preparing for human science on the Moon.

Dr. Young is a leader in developing Concepts of Operation for crews on the Moon and has participated in several operational field tests run by NASA, including as a crewmember and Science Team member for NASA’s Desert RATS, as the Science Operation Co-Lead for NEEMO, as a submersible pilot for NXT, and other analog missions that are maturing ways our astronauts will explore the lunar surface during ARTEMIS missions.

Dr. Young is a Theme Lead for two SSERVI teams, RISE2 and GEODES, where she is involved in testing handheld and field portable instruments and using geophysical instrumentation in human exploration-relevant analog environments. In addition, Dr. Young serves as one of the lead trainers for Earth and Planetary Science training for NASA Astronauts. She served on the 2020 Artemis III Science Definition Team, as part of the Organizing Committee for NASA’s Lunar Surface Science Workshops, as Human Exploration Chair of the LEAG Executive Committee, and as Session Chair at numerous scientific meetings (AGU, LPSC, GSA, NESF, etc.).
She received her PhD and MS in Geological Sciences, from Arizona State University’s School of Earth and Space Exploration, and a BS in Geological Sciences from the Department of Civil Engineering and Environmental Geosciences at the University of Notre Dame.

Within the first two years post-PhD, she won two awards as a PI with NASA’s competitive Planetary Science and Technology Through Analog Research (PSTAR) Program, and has received numerous others, including the 2020 NASA Early Career Achievement Medal, the Wiley-Blackwell Award, the LPI Career Development Award, the 2011 School of Earth and Space Exploration Merit Award, and a NASA Group Achievement Award for her work on Desert-RATS. As an early-career researcher she has an extensive list of publications. Dr. Young has focused her career on a single objective– enabling crewed science on the lunar surface– and the science and exploration communities have each benefitted from this. Young represents the very nexus of lunar science and exploration and is highly deserving of the 2022 Susan Niebur Award.

Orenthal James “O.J.” Tucker is a Research Scientist at NASA GSFC and NASA Postdoctoral Fellow. He earned his Ph.D. and his bachelor’s degree in Mathematics and Physics from Hampden-Sydney College, where he was on both the football team and honor court for math and physics and was active in the minority student union.

As a plasma physicist, Dr. Tucker develops and carries out molecular-level simulations to model gas flows on planetary bodies and to describe radiation effect in solids. His research interests are aimed at understanding how dynamics at the molecular level affects planets and planetary materials. Dr. Tucker is a leading expert on rarefied atmospheres and exospheres across the solar system. He has made significant contributions to exploration science– particularly through his work on the lunar hydrogen cycle and its response to magnetospheric shielding, and on transient atmospheres produced by lunar volcanism. His work has been critical to advancing scientific understanding of the lunar volatile system and provides testable hypotheses for several upcoming orbital and landed lunar missions. The breadth of Dr. Tucker’s work is unparalleled; he has simulated rarefied atmospheres on bodies ranging from Mercury and the Moon, to the moons of Jupiter and Saturn, Pluto and beyond!

In addition, Dr. Tucker has mentored many undergraduate and graduate students and is held in the highest esteem by a wide, international network of colleagues and collaborators. He is currently a Co-Investigator on the SSERVI LEADER team and a Co-Investigator for the PITMS mass spectrometer, a NASA-provided lunar payload. Dr. Tucker has also served in critical leadership and service roles; he is a member of the White House Scientific Integrity Task Force, served as a SOC member for the AAS-DPS, is one of the co-founders of the Planetary Scientists of Color group, and a mentor and role model for the dynamic Black in Astro community.

Dr. Tucker makes an effort above and beyond his own role as a civil servant to bring minority students into the field and these efforts have been inspirational to this community. Because of both his own unique scientific contributions and his constant work to incorporate minority students into his field, Dr. Tucker’s efforts exactly reflect Dr. Susan Niebur’s ‘untiring work at bringing people together and finding ways to help everyone live up to their potential.’ Dr. O.J. Tucker is an exceptional scientist and incredible person and could not be more deserving of recognition.

It is our great pleasure to present both Kelsey Young and O.J. Tucker with this year’s Susan Mahan Niebur Early Career Awards.
