William K. Hartmann, Ph.D.

Hartmann is a founder and Senior Scientist of the Planetary Science Institute. He and Don Davis (see below) are known for developing, at PSI, the current theory of the origin of the Moon by a large planetesimal impact into the forming Earth. Hartmann's current work involves development of the "PSI isochron system" of counting impact craters to infer ages of various planetary surface units. Hartmann holds a Ph.D. in Astronomy and M.S. in Geology from the University of Arizona. He was the first winner of the Carl Sagan Award from the American Astronomical Society, a winner of the G.K. Gilbert award from the Geological Society of America, and a co-winner of the Runcorn-Florensky medal from the European Geophysical Union. In addition to his planetary work, he is known for his astronomical paintings and popular writing, including textbooks, popular science, and two published novels.

William Craig, Ph.D.

Alison Nordt, Ph.D.

Dr. Alison Nordt is the Director for Space Science and Instrumentation at Lockheed Martin’s Advanced Technology Center. She is responsible for developing and operating missions that provide observational data to advance space science knowledge.

She is currently the Principal Investigator for TechMAST (Technology Maturation for Astrophysics Space Telescopes) and several related internal research and development efforts. Previously, Dr. Nordt was the senior manager for Astrophysics and held several roles on the NIRCam (Near Infrared Camera for the James Webb Space Telescope) program including Program Manager, Integrated Product Team Lead and Certified Principal Engineer.

Dr. Nordt has an extensive background in structures, opto-mechanical systems and instrument development which includes engineering experience with design and analysis and hands-on hardware experience through integration and test. She also has diverse program management experience through the program lifecycle from capture through end item product delivery. Dr. Nordt holds Doctor of Philosophy and Master of Science degrees in Aeronautics and Astronautics from Stanford University and a Bachelor of Science degree in Mechanical Engineering from Cornell University. She is an AIAA Associate Fellow.

Alison and her husband have a teenage daughter and son. She enjoys sailing, flying, soccer, alpine skiing, windsurfing and SCUBA diving.

Mark V. Sykes, Ph.D., J.D.

Sykes is the C.E.O. and Director of the Planetary Science Institute. He studies asteroids, comets and interplanetary dust, using both ground-based and space-based telescopes, primarily in the thermal infrared. He is the discoverer of cometary dust trails and many extended structures arising from asteroid collisions within the zodiacal cloud.

Mark is the former Chair of the Division for Planetary Sciences (DPS) of the American Astronomical Society and was made a Fellow of the American Association for the Advancement of Science for his science advocacy. He has been honored by the designation of Minor Planet 4438 Sykes and has also been honored with the 2016 Masursky Award by the Division for Planetary Sciences of the American Astronomical Society for outstanding service to planetary science and exploration. 

Mark received his Ph.D. in Planetary Sciences in 1986 and J.D. in 1998 from the University of Arizona (and is admitted to the Arizona Bar). He is also a professional musician and has performed more than 30 seasons with the Arizona Opera Company's chorus. He is a member of the American Guild of Musical Artists.

Trustee Emeritus
