An optical engineer at NASA's Jet Propulsion Laboratory, Camilo Mejia Prada, shines a light on the interior of a testbed for an instrument called a coronagraph that will fly aboard the WFIRST space telescope. Engineers at JPL are testing mirrors (the small, mounted disks in a line at right) and deformable mirrors (the large, pen-marked disks are stand-ins) that will be part of the coronagraph. This instrument, contained inside the telescope, blocks the glare of stars so that planets around them can be directly imaged. Photo credit: Matthew Luem.
