MARBLE FALLS — A long aluminum tube stretches across two sawhorses at Specialty Machine. On a nearby bench is a matching nose cone that soon will be atop an 18-foot rocket designed and built by Marble Falls High School aeroscience students. The teacher, six students and the rocket leave Aug. 7 for the U.S. Army's White Sands Missile Range in New Mexico, where they will launch the craft Aug. 9 or Aug. 10 depending on the Army and three other schools also making the trip. The aluminum craft will weigh 590 pounds by the time it's fueled and on the launch pad.
