context: -LRB- CNN -RRB- -- After several delays , NASA said Friday that space shuttle Discovery is scheduled for launch in five days . The space shuttle Discovery , seen here in January , is now scheduled to launch Wednesday . Commander Lee Archambault and his six crewmates are now scheduled to lift off to the International Space Station at 9:20 p.m. ET Wednesday . NASA said its managers had completed a readiness review for Discovery , which will be making the 28th shuttle mission to the ISS . The launch date had been delayed to allow `` additional analysis and particle impact testing associated with a flow-control valve in the shuttle 's main engines , '' the agency said . According to NASA , the readiness review was initiated after damage was found in a valve on the shuttle Endeavour during its November 2008 flight . Three valves have been cleared and installed on Discovery , it said . Discovery is to deliver the fourth and final set of `` solar array wings '' to the ISS . With the completed array the station will be able to provide enough electricity when the crew size is doubled to six in May , NASA said . The Discovery also will carry a replacement for a failed unit in a system that converts urine to drinkable water , it said . Discovery 's 14-day mission will include four spacewalks , NASA said .
