Shuttle repair spacewalk is successful.

Miami Herald says it's time to retire the Shuttle.

Discovery's current flight is the 114th of the shuttle program, which launched its first flight in 1981. That's an average of fewer than five flights a year for a program that, when first proposed, was said by NASA to be capable of 60 missions a year. Despite the heartbreaking Challenger and Columbia accidents, the overall record is one of undoubted success. But now that the fleet has been grounded while a shuttle is still in space, it's time to face reality.

I agree. NASA has been derelict in not developing a follow-on vehicle for the 1970's vintage Space Transportation System.
