NASA managers cleared the space shuttle Discovery Friday for its upcoming launch to the International Space Station on Wednesday. Reuters

The shuttle is on a construction mission and is scheduled for liftoff at 9:20 p.m. Wednesday from the Kennedy Space Center in Cape Canaveral, Fla., MSNBC reported.

The fourth and final set of U.S.-manufactured solar wing panels will be delivered to the station by the shuttle, aiding in the $100 billion project that has been under construction by 16 nations for more than a decade, according to Reuters.

The station assembly, which has been a large part of U.S. human space exploration for almost 30 years, is scheduled to be completed next year by NASA.

The launch, originally scheduled for Feb. 12, was postponed due to safety concerns with the ship’s fuel pressure valves, MSNBC reported.

This is the 125th shuttle mission and the first of five planned for this year, according to Reuters. It is scheduled to last 14 days.
