After three delays, space shuttle Discovery is finally on it's way to the International Space Station.
Discovery and its crew of seven lifted off from the Kennedy Space Center in Florida a little before midnight Friday.
Thunderstorms moving into the area threatened to delay the launch a fourth time, but the weather cleared in plenty of time.
Discovery is loaded with some 17,000 pounds of supplies for the International Space Station, including a $5 million treadmill named after Comedy Central's Stephen Colbert.
This mission is scheduled to last 13 days.
