TL;DR

NASA's Nancy Grace Roman Space Telescope now has enough propellant for at least 22 years of science operations—roughly double the original forecast—thanks to a precise SpaceX Falcon Heavy launch, a lighter-than-expected mass, and efficient initial trajectory burns. While a potential uncrewed servicing/refueling mission exists in theory, no servicing spacecraft are currently available; the extra fuel margin reduces near-term refueling needs and supports planned wide-field and coronagraph observations from Roman.
