    spacecraft has enough fuel to reach the intended orbit.  Questions:
    1)  Will they try to get it into the correct orbit, even if they may not
    have enough fuel to do so (if it's an unknown) ?  That could be kind of
    risky, since if they run out of fuel before getting into the right orbit,
    it will eventually dip into low Earth orbit and cause risk to other
    2)  If there is insufficient fuel, would they plummet the spacecraft into
    Earth's atmosphere?  Or settle for a lower orbit which would take the
    satellite all around the Earth?
