NASA’s Deep Space Network (DSN) has brought a new antenna online at its Goldstone complex near Barstow, California. Deep Space Station 23 (DSS-23), a 34-meter (114-foot) multifrequency beam-waveguide antenna, is now operational, according to an announcement from NASA on August 30, 2026.
The antenna is expected to boost the DSN’s capacity and enhance NASA’s deep space communications capabilities for decades to come. NASA leadership and personnel were present at the event, though the announcement did not specify the exact date of the antenna’s first use or the full scope of its operational testing.
A New Addition to the Deep Space Network
DSS-23 is the latest addition to the DSN, a network of radio antennas that supports interplanetary spacecraft missions. The Goldstone complex is one of three DSN sites worldwide, along with Madrid, Spain, and Canberra, Australia. The new antenna’s multifrequency beam-waveguide design allows it to operate at multiple frequency bands, providing flexibility for various missions.
The completion of DSS-23 comes as NASA continues to expand its deep space communications infrastructure to support upcoming missions, including Artemis and Mars sample return. The antenna’s increased capacity will help manage the growing volume of data from these missions.
Technical Specifications and Capabilities
- Diameter: 34 meters (114 feet)
- Type: Multifrequency beam-waveguide antenna
- Location: Goldstone Deep Space Communications Complex, near Barstow, California
- Status: Recently completed, now online
The beam-waveguide design routes signals through a series of mirrors and waveguides, allowing the electronics to be housed in a stationary room, which simplifies maintenance and improves performance. This design is common among newer DSN antennas.
Implications for Deep Space Communications
The new antenna is part of a broader effort to modernize the DSN, which has been in operation since the 1960s. By increasing capacity, DSS-23 will help reduce scheduling conflicts and enable more simultaneous communications with multiple spacecraft. This is particularly important as NASA’s fleet of deep space missions grows.
NASA’s announcement did not provide specific performance metrics or a timeline for full operational capability. The agency has not yet detailed which missions will be the first to use DSS-23 or how much of the DSN’s overall capacity increase it will provide.
What’s Next
The immediate next step is likely to involve commissioning and calibration of the antenna to ensure it meets performance standards. NASA has not announced a specific date for when DSS-23 will be fully integrated into routine DSN operations, but the agency’s statement suggests it will be used for upcoming missions. Observers will be watching for the first spacecraft to communicate via the new antenna.
