Deep Space Station 23: Goldstone Antenna Gets Its Quadripod

A crane lowers a four-legged support structure called a quadripod onto the steel framework of the Deep Space Station 23 (DSS-23) reflector dish on Dec. 18, 2024. The reflector framework was bolted into place earlier in the day, and the quadripod, which weighs 16 ½ tons, was the last major component to be installed that day. The reflector dish will be fitted with panels to create a curved surface to collect radio frequency signals. The quadripod features a curved subreflector that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna's receiver in its pedestal, where the antenna's receivers are housed. The new 112-foot-wide (34-meter-wide) dish is located at the Deep Space Network's Goldstone Space Communications Complex near Barstow, California. A multi-frequency beam waveguide antenna, DSS-23 will come online in 2026, boosting the DSN's capacity and enhance NASA's deep space communications capabilities for decades to come. It is the fifth of six new beam waveguide antennas to be added to the network, following DSS-53, which was added at the DSN's Madrid complex in 2022. The DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. It is managed by NASA's Jet Propulsion Laboratory in Southern California for the agency's Space Communications and Navigation (SCaN) program, which is located at NASA Headquarters within the Space Operations Mission Directorate. https://photojournal.jpl.nasa.gov/catalog/PIA26455
