A SpaceX Falcon 9 launch is scheduled for tomorrow night. The mission will carry NASA’s first planetary defense test mission from Vandenberg Space Force Base. Officials say, the Double Asteroid Redirection Test, or DART, is designed to hit an asteroid while traveling at a speed of 15,000 miles per hour in the fall of 2022. The impact should change the orbit. The launch is scheduled for 10:20 tomorrow night.
