SpaceX’s Falcon 9 rocket is taking off from Cape Canaveral Air Force Station in Florida on Tuesday morning, before the company founded by Elon Musk attempts an unprecedented landing on a barge floating in the Atlantic Ocean.
Launch is scheduled for 6:20 a.m. E.T., and it shouldn’t take much more than 20 minutes before the craft attempts to land 200 miles east of the Florida coast.
