Interstellar (contains spoilers)

Have you seen the movie ‘Interstellar’?

The first nagging question I have is (scroll, text is in strike-through for some obscurity):

How did Cooper know the coordinates to Norad? That’s what really starts the whole process. This is new information he didn’t learn anywhere else except from himself.

Wow, that is so cool!

Well, one would suppose that in the process of planning for the space trip, the coordinates would be pertinent for the launch itself, right?

I’m more concerned with what happened with Anne Hathaway’s character… how long was her (perceived) stay on the planet before the colonists arrived? I presume the ship at the end is a colony ship on its way to the other galaxy…
