NASA has set a time for the launch of STS119 Space Shuttle Discovery. By my calculations it should be 11:54am next Friday the 13th AEDT.
I have updated the event calendar, but I'd appreciate someone doing a check on my time conversion.
Launch time is 8:54pm EDT on March 12 (US Eastern time).
Worth watching if you can get onto NASA TV
