Cloudiness did not stop Endeavour’s launch earlier today, as it skyrocketed off the ground at 4:14 am in Florida.

The U.S. space shuttle shed its two booster rockets within three minutes and was officially in space after about 9 minutes. It travelled at 12,000 mph and made its way to the International Space Station.

It was supposed to head out to space on Sunday, but NASA was forced to postpone due to cloudiness.

While inside the spacecraft, mission commander George Zamka said, “We’ll see you in a couple of weeks. It’s time to go fly.”

To that, launch director Michael Leimbach replied, “Roger that. Have a great flight.”

The 6-crew Endeavour is scheduled for a 13-day mission to install the Tranquility research modules and a cupola. It is scheduled to land at the Kennedy Space Center on February 20 at 10 p.m.
