Hypersonic Vehicle Plummets into Pacific Ocean
News story originally written on June 5, 2001
NASA was testing one of its hypersonic vehicles on Saturday, June 2, 2000. Unfortunately, the vehicle and the rocket booster attached to it went out of control over the Pacific Ocean! Since NASA controllers couldn't control the vehicle, they had to blow it up! A signal was sent to the vehicle causing an explosion of the X-43A hypersonic vehicle and rocket booster. Debris fell into the ocean
These hypersonic vehicles can fly at rocket speeds (hypersonic means at least five times the speed of sound!). The vehicle being tested on Saturday, the X-43A, was suppose to fly at speeds approaching Mach 7 before splashing into the Pacific Ocean. Mach 7 means that the X-43A would have been traveling at seven times the speed of sound!
The X-43A is one of three vehicles NASA is going to test. After NASA looks into this mishap, they will go ahead with the other two flights. Although none of the planes will be recovered (all are scheduled to splash into the ocean), data collected during the flights will be used to build future vehicles that could be used in future space exploration. The X-43A was only 12 feet long with a 5-foot wingspan, but someday hypersonic space traveling vehicles may be over 200 feet long!
