NASA expands Deep Space Network with new 34-meter antenna in California

Deep Space Station 23 at the Goldstone complex will communicate with dozens of robotic space missions and future lunar explorations.

The short version

  • NASA has formally added Deep Space Station 23 (DSS-23), a 34-meter-wide radio frequency antenna, to its Goldstone complex in California.
  • The new antenna began official operations on August 3, 2026, after completing a testing phase, and is communicating with spacecraft including Voyager 1 and Juno.
  • DSS-23 is the fifth dish added under the Deep Space Network's Aperture Enhancement Project, which began in 2009 to modernize space communications infrastructure.
  • The multi-antenna project is scheduled to conclude when a sixth antenna opens in Canberra, Australia, in 2029.

Key facts
