NASA announced that James Webb telescope course corrections used less fuel than expected, which means Webb can expect to work for more than 10 years.
And as NASA announced Wednesday morning, Webb may get to peer deep into the universe for even longer than expected: Webb used less of its limited supply of propellant during two course-correction thruster burns after launch than expected, and the space agency says it should have enough left over to enable operations “significantly” longer than the expected 10-year mission.
