Roman Space Telescope Propulsion Milestones

Technicians don Self-Contained Atmospheric Protective Ensemble (SCAPE) suits as they prepare to perform propellant loading operations inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida for the agency’s Nancy Grace Roman Space Telescope on Thursday, July 23, 2026. With fuel tanks capable of carrying about 290 gallons (roughly 1,100 liters) of hydrazine, 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.
