NASA has reported that evidence of leakage and extensive damage to O-ring seals have been discovered in the nozzle joint of the space shuttle solid rocket boosters after the last two flights. The same joint leakage problems and design flaws that initiated the Challenger disaster, nine years ago, are still present and have not been satisfactorily corrected. As a result of these abnormalities, NASA is seriously considering grounding the shuttle indefinitely. After the Challenger accident, Congress initiated the Advanced Solid Rocket Motor (ASRM)

The explosive loss of an unmanned Titan 34D rocket during a military mission last April was most likely caused by the peeling of insulation inside a solid-fuel booster, the Air Force said today. The loss of the rubberized insulation allowed the burning fuel to eat through the thin metal skin of the rocket booster, touching off a catastrophic explosion, said Brig. Gen. Nathan J. Lindsay.

John Young, head of the astronaut office at NASA's Johnson Space Center in Houston, has questioned the redesign of the solid rocket booster that caused the Challenger accident in light of new information on wind turbulence, a newspaper reported. In a memo, Young voiced concern about the shuttle's ability to withstand dynamic forces it encounters at launching, the Washington Post said in today's editions, quoting unidentified sources.

A spacecraft that broke up last year during a mission to study comets was probably destroyed by the heat from its rocket motor, NASA officials said. The theory is the most probable of four scenarios outlined by the board that investigated the loss of the $159-million Contour. The board found the hot plume of exhaust gases produced by the firing of the solid rocket motor probably caused "structural failure."

Early tests show that a new rocket engine design will eliminate the flaws that caused the space shuttle Challenger to blow up, a National Aeronautics and Space Administration official said Monday. John Thomas, manager of NASA's solid rocket motor redesign team, also said the space agency is on track toward a resumption of space flights in early 1988.

Production of a critical ingredient for solid rocket fuel resumed Monday at a Kerr-McGee Corp. plant, five weeks after explosions destroyed the only other plant making the chemical a mile away. Workers resumed production Monday morning of the chemical, ammonium perchlorate, which provides the oxygen necessary to burn solid fuel in the booster rockets on the space shuttle and in some military rockets.
