POLISHING AND MEASUREMENT of the eight mirrors for the Advanced X-Ray Facility (AXAF), to be deployed by the Space Shuttle in September 1998, have been completed ahead of schedule at Hughes Danbury Optical Systems. The TRW-built AXAF will follow the Compton gamma-ray observatory and the Hubble Space Telescope in NASA's Great Observatory mission series. Its picture-like images and spectrograms will yield information on the most energetic and violent objects in the Universe, including neutron stars and quasars.
