FAULTY INTERNAL SIGNAL CAUSED ROCKET TO BLOW UP

The Conestoga rocket that exploded Monday over the Atlantic apparently received a bad internal signal and self-destructed, its developers said.

EER Systems officials still are trying to determine what caused the $20 million rocket to explode, and expect to release a preliminary report Nov. 3, said Jim Hengle, a vice president of the Seabrook, Md., aerospace company.

The five-story Conestoga blew up 46 seconds after liftoff from NASA's Wallops Flight Facility. The state's first commercial rocket launch, five years in the making, was carrying a load of scientific experiments into space.

The rocket was on course when it received a bad control signal that was full of static, Hengle said. An onboard computer sensed the problem and ordered the Conestoga to self-destruct. NASA officials monitoring the launch also signaled the rocket to destroy itself, but it had already done so.

``The noise distracted the rocket into thinking it was in a location other than where it was,'' he said.

Rocket boosters did not malfunction, Hengle said, which had been suggested last week as a possible cause.
