Jupiter-bound spacecraft's key antenna experiences glitch in deep space.

The European Space Agency reported that the radar antenna on Juice, a spacecraft bound for Jupiter, is jammed and only unfolded one-third of the way following liftoff. Engineers suspect a tiny pin may be protruding and plan to fire the spacecraft’s engine in hopes of shaking the pin loose. The radar antenna is needed to peer beneath the icy crust of three Jupiter moons suspected of harboring underground oceans and possibly life.
