Without power to fire the maneuvering thrusters its orbit will probably degrade fairly rapidly. Also, it's probably more expensive to get the fuel out during a complicated docking operation than it is to just get up new fuel for new missions as needed.

This sucks. It would have been a very cool mission.

The engines failed to fire. All those fuels are not being used. The probe is circling the Earth on inertia. After a while without power the orbit will deteriorate.

Hope they can get the engine to fire before it's too late.
