SpaceX: Attempt to Launch and Land a Rocket on Earth Set For Saturday

Elon Musk's space company hopes to show its rockets can be recovered and reused.

If the feat goes according to plan, SpaceX will have upped the ante in the private space race by showing the capability and the reusability of its rockets.

The nail-biting space spectacle will begin at 4:47 a.m. ET on Saturday when the Falcon 9 rocket launches from Cape Canaveral. The cargo includes critical materials for science and research plus replacement parts for the Space Station toilet, along with personal items and fresh food for the astronauts.

After liftoff, rocket will blast into space and the 14-story first stage of it will detach and hurtle back down to Earth, attempting a pinpoint landing on a floating platform.

The launch was originally scheduled for last Tuesday, but was called off with less than a minute to spare so SpaceX could troubleshoot an issue, according to a tweet from Musk.
