Watch as NASA engineers use a special welding technique known as friction-stir welding to bond new composite metals. See how this process adds strength to the material. Learn to convert degrees Fahrenheit to degrees Celsius. The Ares launch vehicle described in this video never made it to launch, but designs for this mission advanced technology. [Archived 2014 - Not all missions make it from design to launch. These archived videos describe missions that that would have taken humans back to the moon and unmanned aerial vehicles to Mars. While the actual missions were aborted, the technology and science behind the missions pushed innovation to new levels.]
