Arecibo Observatory's giant spherical reflector antenna has undergone a massive upgrading over the past three years. The surface of the reflector has been replaced with aluminum panels to obtain an accuracy of 3.2 mm rms over the reflector surface. The superstructure has been stabilized and modified to permit operation at S-band frequencies. A high-power S-band radar transmitter has been added to the existing UHF system. These additions and improvements provide the observatory with new and promising research capabilities in the fields of radio and radar astronomy.
