The Hubble Space Telescope is in low-Earth orbit and has been repaired multiple times. But spacecraft sent to the Sun-Earth L2 Lagrange Point are beyond the reach of service, whether by robots or astronauts. A new paper proposes trajectories that servicing spacecraft could fly to rendezvous with L2 missions to bring them fresh parts and more propellant to extend their missions indefinitely. They specifically proposed flights to repair Gaia and JWST.
