SUMMARY: NASA has postponed the test of its X-43 prototype because of a problem with the aircraft's rudder. The 4-metre X-43 is affixed to the front of a Pegasus rocket which will be launched from a B-52 aircraft. Once the X-43 is accelerated to Mach 7 on the rocket, it will use its scramjet engine to fly under its own power. Unlike traditional rocket engines, scramjets don't need to carry oxygen to burn rocket fuel. The aircraft uses its speed to compress air from the atmosphere and use this to burn fuel. This allows a scramjet to save weight and carry more cargo. It's unknown when the repairs to the prototype will be completed.
