NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) satellite sits ready for the fairing installation at Launch Pad 17A, Cape Canaveral Air Station. The satellite is scheduled for launch June 24 aboard a Boeing Delta II rocket. FUSE is designed to scour the cosmos for the fossil record of the origins of the universe hydrogen and deuterium. Scientists will use FUSE to study hydrogen and deuterium to unlock the secrets of how the primordial chemical elements of which all stars, planets and life evolved, were created and distributed since the birth of the universe
