NASA said in September 2026 that the Nancy Grace Roman Space Telescope could have an operational lifespan of up to how many years?

Explanation: NASA said the Nancy Grace Roman Space Telescope could have a potential operational lifespan of up to 22 years, even before reaching its planned orbit, reflecting confidence in the mission's design and fuel efficiency. The telescope is designed to conduct wide-field surveys of the universe, complementing the more narrowly focused observations of the James Webb Space Telescope, and is expected to significantly advance research into dark energy, exoplanets and galaxy formation once operational.
