Roman Space Telescope Propulsion Milestones

Self-Contained Atmospheric Protective Ensemble (SCAPE) suits hang on a rack the Multi Operations Support Building on Thursday, July 23, 2026, before technicians began operations to load propellant into NASA's Nancy Grace Roman Space Telescope. Once suited up technicians fueled Roman inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida with 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.
