Space Exploration Technologies test-fired the Falcon 9 rocket slated to make a cargo run to the International Space Station next week. 

Engineers will review results of the static test fire from Saturday as part of a routine dress rehearsal for launch.

The flight will be the first of 12 station supply runs the company, known as SpaceX, will handle for NASA under a $1.6 billion contract. 

SpaceX completed a practice flight to the space station in May, becoming the first private company to reach the orbital outpost. A second company, Orbital Sciences, plans to test fly its Antares rocket before the end of the year.

The Falcon 9 rocket and Dragon cargo ship are scheduled to lift off from Cape Canaveral Air Force Station in Florida at 8:35 p.m. EDT next Sunday.
