Watch: Commercial rocket gets ready for launch

Ever wonder how astronauts get the supplies they need when they're in space? It's not easy, and it's not cheap. One of the ways NASA is working to combat this problem is by using the Commercial Orbital Transportation Services (COTS) program. They are working with outside companies to develop specialized space transportation vehicles.

NASA initiatives like COTS are in use to create a space transportation industry that is safe, reliable and provides cost effective transportation to and from the space station and low Earth orbit.

On Saturday, Orbital Sciences rolled out their Antares Rocket as part of the COTS program. The planned launch day for this mission, dubbed the A-ONE, is April 17, 2013.

The Antares rocket is projected to provide a safe and cost effective way to get items into orbit. It will be able to carry 14,000 pounds into low earth and slightly lighter amounts to go farther into orbit.

Take a look at the video below to see how the rocket made it's long trek to its launching pad at the at Wallops Flight Facility.
