There are long-distance relationships and then there's what The Big Bang Theory's Howard and Bernadette have.

"When one person's in space, that's basically the longest-distance relationship you can possibly have!" Melissa Rauch tells "They're going to put earthly relationships to shame."

Days after tying the knot with Bernadette (Rauch) in the Season 5 finale, Howard (Simon Helberg) fulfilled his lifelong dream by blasting off into space on a NASA mission — and he's still out there when Season 6 premieres Thursday (8/7c, CBS). That's not exactly the most ideal way to start a marriage, but Rauch doesn't mind.
