According to recent news out of NASA, the next time the Discovery crew take their ship into orbit, the "force" will be with them -- because they're taking Luke Skywalker's lightsaber along for the ride. That's right, for the film's 30th anniversary, the original lightsaber prop from the first Star Wars film is taking a ride into actual space... but that's not all. Apparently, Chewbacca will be on hand to pass the saber to officials from the Houston Space Center, and then together with Jango and Boba Fett, he will help push a plane back on the tarmac (for reasons unknown to us). But wait, there's more. When the Discovery lands in Houston after its space travels, the crew will be greeted by a group of Stormtroopers and other "Star Wars notables," including the much-loved R2-D2, who will then deliver the lightsaber to a waiting line of Hummers. Afterwards, there will be a party at the Mos Eisley Cantina, where Figrin D'an and the Modal Nodes will play a set of their greatest hits.

If you hadn't been taking the plane apart now when we're trying to get out of here, you wouldn't have to push the Millenium Falcon plane out of the Rebel Alliance ice hangar across the tarmac.

Pushing the plane only suggests poor Wookie workmanship!
