...rocket blew up on launch at California's Vandenberg Air Force Base while trying to lift a Big Bird photo reconnaissance satellite into orbit. And just two days before the anniversary ceremonies were held last week, yet another U.S. space failure occurred: the main engine of a $30 million Delta rocket carrying a $57.5 million weather satellite shut down just 71 seconds after lift-off from Cape Canaveral. The Delta was destroyed by ground command. "We like to feel we're infallible," Shuttle Astronaut Bob ) Crippen told the subdued workers at the cape. "We're not. We proved that...

...suspect in the April 18 Titan failure is also a booster rocket. But a burn-through caused by faulty insulation seems the likeliest explanation. As for the Delta failure, two unexplained surges of high current in the main engine's electrical circuits apparently lowered battery voltage, leading to the premature shutdown. This possibility had been detected in 1974. Some corrections were made then, but not to the circuit that failed...

None of the three remaining shuttles, which can lift as much as 65,000 lbs., are expected to fly until the summer of 1987. The Titan 34D, which can put 27,500 lbs. into orbit, will be grounded for at least six months. The Delta, which had run up 43 successes since the last failure in 1977, has a 7,500-lb. lift capability that will be lost until August. The nation's other medium-lift rocket, the Atlas-Centaur (13,500 lbs.), was scheduled to loft a Navy satellite on May 22, but that launch has been postponed until...

...effective than the Big Bird, is still operational, keeping special watch on the Soviet Union and the Middle East. It has enough maneuvering fuel to last at least another year. Similarly, the National Oceanic and Atmospheric Administration has an orbiting weather satellite identical to the one lost in the Delta accident and expects it to continue performing for at least two years. Nonetheless, concedes NOAA Spokesman Joseph LaCovey, "the single satellite doesn't give us as good a view as we would like...

...sleek three-stage Delta roared off its pad at 6:18 p.m. Saturday after a trouble-free countdown. Its main liquid-fuel engine and solid-fuel boosters all fired as planned. Delta soared into the clear Florida sky. Then, 71 seconds into its flight, monitoring technicians experienced a chilling case of deja vu. Their instruments showed that the main engine had shut down before it was programmed to do so, causing Delta to lose its flight stability. Veering out of control, the rocket began to break up. At 91 seconds, range safety officials destroyed it by remote control...
