Nation IN BRIEF : FLORIDA : Computer Circuit Problem on Shuttle

NASA said it would try to bring Columbia back to Earth today after a computer circuit involving the space shuttle’s wing flaps, rudder and brakes failed. The shuttle has three identical backup circuits, and NASA officials at Florida’s Kennedy Space Center said the seven astronauts were in no danger. Under NASA rules, the loss of even one of the circuits dictates a return to Earth as soon as possible. NASA dispatched a team to the shuttle’s backup landing site at Edwards Air Force Base, Calif., in case the weather there is better.
