SpaceX makes historic attempt to land rocket on Earth

SpaceX will attempt the first orbital launch of 2015 Tuesday morning to re-supply cargo to the International Space Station from Cape Canaveral Air Force Station in Florida.

The California-based private spaceflight company will do something unusual in this mission, as this time it aims for a vertical test landing of a two-stage Falcon 9 rocket, topped by a Dragon capsule that’s loaded with essential supplies on a barge in the Atlantic. After the booster falls away and the second stage continues pushing the payload to orbit, its engines will re-ignite to turn it around and guide it to a spot about 200 miles east of Jacksonville, Fla.

SpaceX chief Elon Musk predicts a 50-50 chance of success at best. He says flying back boosters would allow them to be reused and save money.
