(NASA) – Expedition 20 Commander Gennady Padalka and flight engineers Michael Barratt, Roman Romanenko, Frank De Winne, Robert Thirsk and Koichi Wakata will have to wait a little longer for the arrival of space shuttle Endeavour and the International Space Station’s newest crew member.

Shuttle controllers postponed the launch of the STS-127 mission to the station due to lightning and thunderstorms within the 20-nautical-mile circle around the launch pad.

Another attempt is slated for Wednesday at 6:03 p.m. EDT. The space shuttle Endeavour crew will complete construction of the Japan Aerospace Exploration Agency’s Kibo laboratory and deliver a new crew member to the orbital outpost.

Flight controllers are continuing to assess the performance of one of the station’s eight beta gimbal assemblies that stalled Thursday. These joints allow the station’s solar arrays to tilt toward the sun as they generate power. Over the weekend, controllers were able to operate the joint in both directed positions and automatic sun-tracking modes.

Beta gimbal assembly operations are now back to normal. Engineers believe the stall was caused by thermal conditions at the current high beta angle but are continuing to evaluate.
