NASA budgeted 200 kilograms of fuel for Roman’s first course correction, but the telescope used only 18. Combined with extra fuel loaded before launch and further expected savings, that could stretch its 10-year fuel plan to at least 22 years. - Space Daily

Roman's first correction used nine percent of its 200-kilogram allocation. NASA now projects enough propellant for at least 22 years, while stressing that later savings remain conditional.

NASA’s Nancy Grace Roman Space Telescope began its journey to the Sun-Earth L2 region with a propellant budget built around uncertainty. The first major test of that reserve has produced a result far… [+10580 chars]
