Roman Space Telescope Propulsion Milestones

Technicians monitor propellant loading from a control room in the Multi Operations Support Building at NASA’s Kennedy Space Center in Florida Friday, July 24, 2026. With fuel tanks capable of carrying about 290 gallons (roughly 1,100 liters) of hydrazine – a monopropellant not requiring a second chemical to combust – Roman’s primary mission is to settle essential questions about dark energy, exoplanets, and infrared astrophysics by conducting wide-field surveys that explore the universe’s structure, evolution, and composition. Liftoff atop a SpaceX Falcon Heavy rocket from NASA Kennedy’s Launch Complex 39A is targeted no earlier than Sunday, Aug. 30, 2026.
