The vacuum chamber at NASA's Jet Propulsion Laboratory in Pasadena, California, used for testing WFIRST and other coronagraphs. A star is simulated inside the chamber using light brought in by an optical fiber, and the light of this "star" is suppressed in the testbed by coronagraph masks and deformable mirrors.

WFIRST is managed at Goddard, with participation by NASA's Jet Propulsion Laboratory in Pasadena, California, the Space Telescope Science Institute in Baltimore, the Infrared Processing and Analysis Center, also in Pasadena, and a science team comprised of members from U.S. research institutions across the country.
