We are delighted to host this year’s AAVSO Annual Meeting at the U.S. Space & Rocket Center (USSRC) in Huntsville, Alabama. Home to Space Camp, Aviation Challenge Camp, Space Camp Robotics, and the U.S. Cyber Camp the USSRC is the most comprehensive U.S. manned spaceflight hardware museum in the world. From a model of America’s first satellite, Explorer I, to next generation space vehicles like Sierra Nevada’s Dream Chaser, the museum showcases the past, present and future of human spaceflight. USSRC serves as the official NASA Visitor Center for Marshall Space Flight Center and is an affiliate of the Smithsonian Institution.

Keynote Speakers
Arlo Landolt Lecturer: Dr. Bradley E. Schaefer
Dr. Brad Schaefer has been a passionate amateur astronomer since 1969, and has since witnessed seven total solar eclipses, managed—in his own words—a gazillion public skywatching nights and star parties, captured eleven Astronomical League Observing Awards, and authored 29 Sky & Telescope articles. He maintains substantial databases of naked-eye observations for historical applications. In 1973, he submitted his first AAVSO observation, and attended his first AAVSO annual meeting in Concord in 1975.
He earned MIT degrees in 1978 and 1983, worked at NASA Goddard for a wonderful decade, then moved to professorships at Yale and Louisiana State University (where he served as the ‘replacement’ for Professor Landolt on his official retirement).
Schaefer’s scientific highlights include his work in the Supernova Cosmology Program, and as one of the discoverers of Dark Energy, which earned him a share of the 2007 Gruber Prize in Cosmology and the 2015 Breakthrough Prize in Fundamental Physics. For his entire career, he has focused mainly on exploding stars—recurrent novae, novae, supernovae, gamma-ray bursts—making very heavy use of AAVSO data and tools. | Talk Abstract
Dr. John Blevins
Dr. John Blevins is the Chief Engineer for NASA’s Space Launch System Program, managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama. He helps direct the SLS Engineering efforts and oversees the SLS Chief Engineers Office.
Prior to this assignment, Dr. Blevins served as the SLS Deputy Chief Engineer. He previously served as Technical Assistant in the Structural Design and Analysis Division in the Spacecraft & Vehicle Systems Department, where he was the Aerodynamics sub-discipline lead for SLS, the lead for the SLS Buffet and Vibroacoustics Resolution Task Teams, and the SLS Alternate Discipline Lead Engineer for Structures and Environments.
His other work since coming to Marshall in 1999 include propulsion researcher and principal investigator as well as a combustion devices engineer before becoming a team lead in Aerodynamics. On a detail assignment, he served as Aerosciences Branch Chief in 2016.
Before his work at NASA, Dr. Blevins gained industry experience at Honda of America Manufacturing, and Sverdrup Technology Group (now Jacobs Engineering). He is both an Associate Fellow of the American Institute of Aeronautics and Astronautics and a licensed Professional Engineer. He is also an experienced pilot with airline transport pilot and flight instructor ratings. Dr. Blevins earned a Bachelor of Science in Mechanical Engineering from Tennessee Technological University, and attained both a Master of Science and a Doctorate in Mechanical and Aerospace Engineering from the University of Alabama in Huntsville. | Talk Abstract
Dr. Sukanya Chakrabarti
Dr. Sukanya Chakrabarti is the Pei-Ling Chan Endowed Chair in the Department of Physics and Astronomy at the University of Alabama in Huntsville. She has worked broadly across many areas of astronomy, and recently has led the development of techniques and observing campaigns to directly measure the small accelerations of stars that live within the gravitational potential of the Milky Way, which provide the most direct probe of the mass distribution in the Galaxy. These recent measurements now enable the new, highly interdisciplinary field of “real-time” Galactic dynamics that brings together the exoplanet community, researchers in compact objects and eclipsing binaries, and in traditional Galactic dynamics. Our team now has the first direct measurements of Galactic accelerations and dark matter constraints in the Milky Way, and they give us a very different picture of our Galaxy than prior work. | Talk Abstract
