22 years of science! NASA's Roman Space Telescope doubles its lifetime with super-precise engine burn

From 10 to 22 years: The Nancy Grace Roman Space Telescope's mission has just been extended

The Nancy Grace Roman Space Telescope hasn't yet reached its Sun–Earth L2 orbit, and it already has some good news. NASA has announced that the mission has enough fuel to potentially double its mission length. Though initially scheduled for five years of observations, followed by a five-year extended mission, the entire mission could now reach 22 years.
