Yes it is. It's 'Bathed in the Light' by Kevin McLeod. He's got a nice site (incompetech.com) filled with royalty free music. Great for low-budget game devs like myself. Sounds like KSP picked one of the same songs I did.

Thanks for the link! That's going in my bookmarks.

Great game, by the way.

Thanks! And no problem about the link. I'll warn you, though, once you listen to his music, you'll start to hear it everywhere in games. So listen at your own peril :)
