CAPE CANAVERAL, Fla. (AP) -- It will be the second attempt to send Endeavour on its final voyage. On April 29, an electrical problem prevented the shuttle from blasting off. The trouble was traced to a switch box. The box was replaced, and technicians installed new wiring that bypasses the original circuitry.
Commander Mark Kelly will lead the six-man shuttle crew. He's
married to Rep. Gabrielle Giffords, who was critically wounded in
Tucson in January. The congresswoman's staff says she will return
for the next launch attempt.
Endeavour is loaded with a $2 billion particle physics experiment for the International Space Station.
