(NBC News) With support from NASA, a Virginia company successfully launched an unmanned rocket this morning.
The Antares rocket and Cygnus spacecraft were made by Orbital Sciences Corporation of Dulles, Virginia.
The spacecraft is carrying about 1,500 pounds of clothes, food and water to astronauts onboard the International Space Station.
This is called a "demonstration" mission to prove that Orbital has the hardware and know-how to send cargo to the station.
Another company, SpaceX, has done it twice already.
A successful mission for Orbital would greatly please NASA officials who would like to have more options for supplying the station.
Today's rocket is scheduled to rendezvous with the Space Station on Sunday.
