This is a glitch that I like to call the Universe-breaker. Not too sure how it happens, but it will basically destroy everything... crashing into the ground sometimes triggers it.

Be warned, if you launch a new flight, map view will show nothing, and Kerbin will not have an atmosphere. Also, if you get into orbit, then Kerbin will fade away. The only way to fix it is to restart KSP.

NaNs somewhere?

You had a kerbal jump from a ladder onto the ground, didn't you? Exiting the game to the desktop and starting it up again should fix it, though the mission you were flying my just be flying debris when you get back to it.
