In 1987, Tim Hunter and Dr. David Crawford founded the International Dark-Sky Association, Inc., to promote quality outdoor lighting and combat the effects of light pollution.

Pam Melroy is a retired Air Force test pilot and former pilot and commander of the Space Shuttle. She received a B.A. degree in Physics and Astronomy from Wellesley College in 1983 and an M.S. in Earth and Planetary Sciences from Massachusetts Institute of Technology in 1984. Melroy has logged more than 6,000 hours flight time in more than 50 different aircraft. After NASA, she worked at Lockheed Martin on the Orion program, and was acting Deputy Associate Administrator for Commercial Space Transportation at the Federal Aviation Administration. She most recently served as Deputy Director, Tactical Technology Office at the Defense Advanced Research Projects Agency (DARPA).

Scott D. Fouse

Scott Fouse is the owner of Fouse Consulting Services, LLC, based in Scottsdale, Arizona. He works with a variety of companies helping them harness advanced technology to enable future products and processes. He retired in April, 2018 from his position as Vice President of the Advanced Technology Center at Lockheed Martin Space. In this role, he was responsible for leading approximately 500 scientists and engineers performing research and development in space science and a variety of space systems related technologies and capabilities. Prior to ATC Scott served as Director of the Lockheed Martin Advanced Technology Laboratories (ATL) which is a group of about 220 researchers primarily focused on advanced information technologies. Previous to this role he was Chief Technology Officer (CTO) of ATL. Before coming to Lockheed Martin, Scott was President and CEO of ISX Corporation, a 50 person company that specialized in creating and transitioning advanced IT systems to operational use. Scott was a leader in the DARPA Command Post of the Future project, which created a significant advance in C2 Systems and was the primary C2 system for Iraq at the Corp. Division, Brigade and Battalion echelons. Shortly after ISX Corporation was formed in 1988, it partnered with a professor at MIT, Dr. Rodney Brooks, to create IS-Robotics. This company was focused on finding commercial opportunities for intelligent systems in the general area of Robotics. In 1998 IS-Robotics was renamed iRobot. Scott was a member of the Air Force Scientific Advisory Board from 2003 to 2007. In that position, he supported a number of studies, directorate reviews, and also chaired a study on Experimentation to support Disruptive Innovation. Scott has a BS in Physics from the University of Central Florida, and a MS in Electrical Engineering from the University of Southern California.

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.

Erin Neal

Neal is the founder and sole proprieter of Velocity Government Relations, serving the aerospace and defense communities in Washington, D.C. She is currently Vice President and Programs Chair for the Washington Space Business Roundtable and is slated to take over the helm of that organization in mid-2018. She is a past President of both the National Space Club and Women in Aerospace, and a prior Board Member of the American Astronautical Society. Neal has a Bachelor of Science in Physics from the Centenary College of Louisiana and a Master's in International Science, Technology and Public Policy from The George Washington University. Neal taught math and science as a Peace Corps Volunteer in Cameroon, Central Africa, and while conducting original space research at the University of Texas at Dallas, Arecibo Observatory in Puerto Rico, and at the Lunar and Planetary Institute adjacent to Johnson Space Center in Houston. She was a policy analyst for the Congressional Research Service, the National Academy of Sciences, NASA Headquarters and the Space Policy Institute. She has also served as a senior staffer to U.S. Senator Bill Nelson (D-FL) and as a staff member for two Members of the U.S. House of Representatives. In her spare time, Erin leads a Girl Scout troop focused on STEM, community service, and the great outdoors.

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. He is the former Chair of the Division for Planetary Sciences 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).  Mark is also a professional musician, performing more than 30 seasons with the Arizona Opera Company in its chorus. He is a member of the American Guild of Musical Artists.
