This teaser for Angry Birds Space not only has the cooperation of NASA, it was filmed on the International Space Station, featuring a live Angry Birds demonstration and physics lesson from astronaut Don Pettit.
All right, Rovio, that's pretty damn cool. As a nice bonus, there's gameplay footage at the end too, showing what appear to be weightless environments, many built around small circular planets.
Update: Rovio has sent along some screenshots and some more information. Angry Birds Space will feature 60 levels, new birds, new abilities, secret bonus levels and, of course, the gravity tricks seen in the trailer. The app will receive "regular free updates" and will feature in-app purchases.
