Shuttle Discovery Launch Delayed Again

NASA has again delayed the launch of space shuttle Discovery on its STS-128 mission. The delay is just shy of 24 hours. The new launch date is still tomorrow, Friday, August 28, but instead of 12:22 am EDT it is 11:59 pm EDT. According to NASA’s press release, “NASA managers decided Thursday that more time is needed to analyze the test data and develop alternative procedures for confirming that the valve is closed if the valve fails to provide the proper closed indication during Discovery’s next launch attempt.” According to NASA, the weather tomorrow is 40% no-go for tanking and 40% no-go for launch.
