Foreign object debris shields are installed and a borescope inspection is conducted on the Galaxy Evolution Explorer (GALEX) spacecraft in the Payload Hazardous Servicing Facility. On the left is the Pegasus launch vehicle from which it was demated. Technicians are looking for a small fastener and associated clip missing from a demated connector identified during preflight testing. GALEX is an orbiting space telescope that will observe galaxies in ultraviolet light across 10 billion years of cosmic history. During its 29-month mission, GALEX will produce the first comprehensive map of a Universe of galaxies under construction, bringing more understanding to how galaxies like the Milky Way were formed. The GALEX launch date in late April is currently under review.
