ICE is returning to Earth; but do we have the will to regain control?, Planetary Society
"When it comes back to Earth, it would be possible to recapture it into a halo orbit (that is, an orbit at the L1 point). But to do that, we'll have to reestablish regular communications with, and control of, the spacecraft. It won't be easy, but it's doable. But it will cost money, and given the current financial problems in Washington, it's unclear where that money will come from."
