(Newser) – The Space Shuttle Discovery’s mission to deliver the final piece of a solar power array to the International Space Station was delayed again today, only hours before scheduled launch, CNN reports. The mission had already been postponed a month so technicians could determine whether three valves that control fuel supply were in danger of breaking; continued concerns over the valves caused today’s delay.
