Dr. Charles Swanson is the senior scientist at Princeton Satellite Systems. He completed his Ph.D thesis on the PFRC-2 plasma confinement and heating experiment at the Princeton Plasma Physics Laboratory in September 2018. Its title was “Measurement and characterization of fast electron creation, trapping, and acceleration in a high-mirror-ratio, low-beta magnetic mirror.” Prior to beginning his graduate work, he interned at SpaceX, working on Electromagnetic Interference for the Dragon and Falcon spacecraft.

Dr. Deana L. Weibel is a Professor at Grand Valley State University in Allendale, Michigan, jointly appointed in the Department of Anthropology and the Department of Integrative, Religious and Intercultural Studies (IRIS). While most of her early work focused on religious pilgrimage and sacred places (such as Rocamadour, France and Chimayó, New Mexico), current work examines the religious perspectives of people involved in space exploration. A recent sabbatical involved ethnographic fieldwork at the NASA Human Research Investigators Workshop, the Kennedy Space Center, the Mojave Air and Space Port, the Jet Propulsion Laboratory and the Vatican Observatory. Weibel’s interview subjects have included engineers, astronauts, astronomers, test pilots and aerospace physicians, and her goal is to better understand how scientific and religious perspectives are separated and/or integrated among people whose work gives them expert knowledge about “the heavens”. Relevant publications include “Malinowski in Orbit: ‘Magical Thinking’ in Human Spaceflight” (with Glen E. Swanson), “Magnetism and Microwaves: Religion as Radiation,” “’Up in God’s Great Cathedral’: Evangelism, Astronauts, and the Seductiveness of Outer Space, ” and “Pennies from Heaven: Objects in the Use of Outer Space as Sacred Space.”
