The Hubble telescope is back in service and doing science again.Kepler, unfortunately, is dead.
No, not Johannes Kepler. He died in 1630. The Kepler Space Telescope named after him. Nine and a half years into its planned five-year mission, after discovering 2,681 confirmed exoplanets and many more "possibles", it has finally run out of fuel for its maneuvering/positioning thrusters. 94 million miles from Earth, there's not a hope of a refueling mission.
Kepler, we salute you. It's time to rest now.
