The Roman telescope has enough gas for 22 years, double NASA's expectations
NASA's Nancy Grace Roman Space Telescope is gliding toward its distant observation post on a pinpoint trajectory so precise that engineers estimate the spacecraft's fuel load will last twice as long as their initial expectations, the space agency confirmed Monday. The $4.3 billion observatory's designers originally planned to load enough propellant into Roman's four fuel tanks for a minimum lifetime of five years, plus a potential five-year mission extension. That was a conservative estimate. NASA officials knew an on-target launch and perfect execution of the observatory's first post-launch course correction maneuver would leave Roman with a hearty fuel reserve. "As a result of exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX, Roman has fuel for at least 22 years of potential science operations," Jamie Dunn, center director at NASA's Goddard Space Flight Center, said in a press release.

The Nancy Grace Roman Space Telescope is the first NASA observatory designed for in-space refueling.
The James Webb Space Telescope received a similar lifetime boost after a picture-perfect launch on a European Ariane 5 rocket in 2021.
The Roman telescope launched August 30 from NASA’s Kennedy Space Center in Florida aboard a SpaceX Falcon Heavy rocket, kicking off a mission to widen our view of the Universe. Roman’s telescope and scientific instruments will provide astronomers with images of the sky at the same resolution as NASA’s Hubble Space Telescope, but with 100 times the field of view. It would take Hubble a century to observe what Roman will see in a month.
