As the countdown for the Discovery launch is ready to begin, the mission’s management team has given green light for Wednesday’s event. No technical issues have been reported, and the weather seems favorable for the launch.

The STS-119 members arrived at the Kennedy Space Center in Florida on Sunday. The crew of seven includes Commander Lee Archambault, who will lead Discovery's team, along with Pilot Tony Antonelli, and Mission Specialists Joseph Acaba, John Phillips, Steve Swanson, Richard Arnold and Japan Aerospace Exploration Agency astronaut Koichi Wakata.

The shuttle Discovery is preparing for a 14-day mission, during which it will deliver the final set of solar array wings for the International Space Station to complete the station’s truss. The mission was initially scheduled to launch on February 12, but it has been delayed multiple times.

According to NASA, the mission will include four spacewalks, during which the crew will install the final set of solar arrays, in addition to replacing a failed unit for the system that converts urine into potable water. Each of the four spacewalks is scheduled to last approximately 6.5 hours.

STS-119 Mission Management Team Chair Mike Moses said in a statement that during the short meeting yesterday, there weren’t too many issues to discuss. This afternoon at 3 p.m. EDT, NASA will begin fuel cell loading.

The mission is scheduled to launch on Wednesday, March 11, at 9:20 p.m. EDT. The countdown will begin at 4 p.m., and NASA promised updates on its blog about the mission progress.
