Technicians verify that the Galaxy Evolution Explorer (GALEX) spacecraft is secure on its workstand after being moved into a vertical position in the Payload Hazardous Servicing Facility. On the right is the Pegasus launch vehicle from which it was demated. A borescope inspection will be conducted on the spacecraft to locate 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.
