LIVE Rocket Launch - Watch as SpaceX launches the top secret Boeing X-37B spaceplane on a Falcon 9 rocket. The launch window opens at 9:50am EDT. The first stage of the rocket will make a landing attempt about eight minutes after launch. Edit: you guys, the MISSION is top secret. The launch clearly is not, as they're a little hard to hide. But we don't know the purpose of the space plane. | IFLScience
