The UltraViolet Spectro-Coronagraph (UVSC) Pathfinder undergoes inspections by two UVSC engineers, after the successful completion of its thermal vacuum test at the U.S. Naval Research Laboratory. The front, gold-colored, aperture shows the multiple external occulters that will block direct light from the solar disk. The occultation allows the faint solar corona to be observed at Lyman-alpha wavelengths. The UVSC instrument sits on a transport cart, which is not part of the flight package. (U.S. Navy Photo)
