NASA’s New 114-Foot Deep Space Dish DSS-23 Is Live. Here’s How It Keeps You Connected to Mars and Voyager

Somewhere in the Mojave Desert, NASA just switched on a powerful new voice for deep space communications. This is Deep Space Station 23, or DSS-23, a 34 meter wide (114 foot) radio dish at the Goldstone Deep Space Communications Complex near Barstow, California. It is now part of a global network of antennas that keeps more than 40 spacecraft connected to Earth, from Mars orbiters to interstellar travelers like Voyager 1.

What does it take to keep talking with a spacecraft millions of miles away? For NASA, part of the answer is a giant metal dish that can send and receive signals across the solar system. DSS-23 is the latest result of the Aperture Enhancement Project, an upgrade program started in 2009 to modernize the Deep Space Network with six new 34 meter antennas. On Aug. 25, 2026, NASA leadership, Jet Propulsion Laboratory officials, and the project team gathered beneath the completed dish for a ribbon cutting ceremony that marked the start of its official service.

DSS-23 went through an intense testing period from May through July before beginning routine operations on Aug. 3, 2026. In its first weeks on the job, it locked onto the Mars Reconnaissance Orbiter, Psyche, Juno, Voyager 1, and many other robotic explorers. The dish operates across multiple radio frequencies, which gives it the flexibility to support missions with different communication needs.

Building this antenna took years of careful work. Construction began in February 2020. In December 2024, crews lifted the antenna's 133 ton metal reflector framework onto its pedestal. After that, technicians installed precision panels that reflect radio frequency signals traveling to and from spacecraft. A thorough calibration process followed to make sure DSS-23 works in sync with the rest of the Deep Space Network.

The engineering behind DSS-23 is clever in a practical way. It uses a multifrequency beam waveguide design. The design routes signals down into a stable, climate controlled underground room, so heavy electronics never have to ride on the moving dish. That makes the system easier to maintain, more reliable, and simpler to upgrade over time. For a network designed to serve NASA for decades, that kind of flexibility matters.

DSS-23 is the fifth antenna at Goldstone, joining three other 34 meter dishes and one 70 meter (230 foot) giant. It is also the fifth of six antennas planned under the Aperture Enhancement Project. The sixth dish is expected to come online at the Deep Space Network's Canberra, Australia facility in 2029. When that happens, the network will have 13 modern 34 meter antennas spread across its three global sites.

There is another reason these new antennas matter. Multiple 34 meter dishes can be arrayed together to act as a backup for a facility's 70 meter antenna. The 70 meter dishes have served for more than 50 years, and adding modern, sustainable antennas gives the network more options for the future. This is how NASA is future-proofing its deep space communications backbone.

The Deep Space Network is managed by NASA's Jet Propulsion Laboratory under the Space Communications and Navigation Program, known as SCaN. More than 100 NASA and non-NASA missions rely on it. That includes human spaceflight support for astronauts on the International Space Station and the upcoming Artemis missions. The network also enables Earth observation, lunar exploration, planetary science, and missions traveling to the edges of the solar system and beyond.

With DSS-23 online, NASA's communications infrastructure is stronger and more flexible. Every new dish adds more than just receiving power. It adds capacity for discoveries that have not happened yet. The next signal from a distant spacecraft could arrive at a dish like this, and somewhere on Earth, someone will be listening.
