The Galaxy Evolution Explorer (GALEX) spacecraft is lifted away from the Pegasus XL launch vehicle after demating. Foreign object debris shields will be installed before its launch. The 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 how galaxies like the Milky Way were formed. The GALEX launch date is under review.
