In August 2020, SpaceX’s Crew Dragon capsule splashed down off the Florida coast following its first crewed mission. But the two astronauts inside could not exit the capsule immediately; technicians outside had to confirm there were no airborne vapors from hydrazine, a highly toxic fuel used by the vehicle’s hypergolic thrusters. Now, Purdue combustion researchers are investigating a safer and less toxic hypergolic propellant, studying its explosive reaction with a new technique involving both visible and infrared high-speed cameras.
