Overview
- The mission team says the Aug. 31 midcourse correction used about 18 kilograms of propellant versus roughly 200 kilograms budgeted, a burn the agency calls more than 99% accurate.
- Roman launched lighter than engineers had conservatively planned so teams filled the tanks to capacity before flight, which added several years to the observatory’s propellant baseline.
- NASA has powered on the Wide Field Instrument and returned an initial test image showing first photons, and it has started early checks and a roughly 30-day decontamination for the Coronagraph Instrument.
- The telescope is en route to the Sun–Earth L2 point with a small second course correction planned, an expected L2 insertion in early December, about 100 days of commissioning, and first public science images due in early 2027.
- The extra fuel could enable far longer wide-field surveys and more exoplanet technology demos, but the 22-year figure is a potential estimate that depends on future maneuvers, instrument health, and funding.
