Ask any deep space navigator like Jill Seubert what makes steering a spacecraft so difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure.
So what do you do when a spacecraft is bad at telling time?
You get it a clock -- an atomic clock, to be precise.
Let Seubert whisk you away with the revolutionary potential of a future where you could receive stellar, GPS-like directions -- no matter where you are in the universe.
