Reusable Rocket Explodes in Test

An experimental reusable rocket developed to test technology for the next-generation U.S. space shuttle fleet exploded during a test flight at White Sands Missile Range, NASA officials said. The Delta Graham, part of a $50-million NASA program to develop new rocket components, caught fire and exploded after two of its four landing gear malfunctioned as the craft eased back to a landing pad following a brief flight. The unmanned rocket was being piloted with remote controls on its fourth and final test flight by ex-astronaut Pete Conrad. Remote firefighting equipment extinguished the blaze and there were no injuries.
