The Roman telescope has enough gas for 22 years, double NASA's expectations
The Nancy Grace Roman Space Telescope is the first NASA observatory designed for in-space refueling.
NASA’s Nancy Grace Roman Space Telescope is zipping towards its observation spot with an impressive fuel reserve that could keep the spacecraft operational for up to 22 years, more than double what engineers originally anticipated. The $4.3 billion telescope’s fuel capacity was initially planned to last for a minimum of five years, with a potential extension of another five years—considered a conservative estimate.
However, NASA officials recognized that a successful launch and flawless execution of the observatory’s first course correction maneuver would significantly boost Roman’s fuel supply. Jamie Dunn, director at NASA’s Goddard Space Flight Center, disclosed in a press release that the telescope now boasts a fuel reserve capable of supporting at least 22 years of scientific observations.
