Story summary

NASA says the Roman Space Telescope will have fuel for at least 22 years of science.
Its final mass was two tons below the limit, allowing full tanks and about four extra years.
The Aug 31 correction burned 40 pounds, under 10% of budget, saving fuel for September and adding four years.
Goddard director Jamie Dunn and propulsion lead Alison Rao said planning enabled the fuel extension.

History

Historical Context

NASA’s 1970s push for a Large Space Telescope led to Hubble’s 1990 launch, whose flawed mirror required the costly 1993 Servicing Mission 1—$500 million in repairs—to restore vision. That success established a model of in-orbit upgrades, which the agency now applies to the Roman Space Telescope, whose 2024 fuel plan adds four years of dark-energy observations.
