Description : (La description de cette image n'existe qu'en anglais)
This photo shows a close-up, rear view of the X-43A Hypersonic Experimental Vehicle, or ''Hyper-X'' undergoing ground testing at NASA's Dryden Flight Research Center, Edwards, California in December 1999. The X-43A was developed to research a dual-mode ramjet/scramjet propulsion system at speeds from Mach 7 up to Mach 10 (7 to 10 times the speed of sound, which varies with temperature and altitude).
