The Endeavors of Endeavour
Today’s planned launch of the space shuttle Endeavour has been delayed until Monday at the earliest; engineers detected a malfunction in a unit that provides the hydraulic pressure needed to control the shuttle during takeoffs and landings. With luck, it will be the last glitch in the long story of Endeavour, which has flown 24 times since its maiden voyage in 1992 and will be retired after a final 14-day mission to the International Space Station.
