Just saw this in the upcoming schedule: Elon Musk will be on The Colbert Report on Wednesday, July 28th. http://www.colbertnation.com (see "Upcoming Guests" section on right side) I don't know if he's there to talk about Tesla or SpaceX or both, but he's billed there as CEO of SpaceX, so that'll probably be the topic. The next SpaceX Falcon9/Dragon test flight isn't expected until early September.
