NASA adds new deep-space antenna as Artemis strains global network
NASA activated a 34-metre antenna at its Goldstone complex in California, the fifth of six planned upgrades to the Deep Space Network (DSN). The network, which serves over 40 missions including Europe's Mars rovers, is struggling to keep up with demand from the Artemis lunar programme and other agencies, per JPL.
Bottom line — The DSN's €333 million ($362.4m) expansion is now 68% over budget and five years behind schedule, with the final antenna due in 2029.

- The DSN operates three complexes: Goldstone (California), near Madrid (Spain), and Canberra (Australia). The Madrid station is a key link for European Space Agency missions, per Space.com.
- DSN manager Brad Arnold warned that Artemis crewed missions will be 'the gorilla in the room,' forcing robotic spacecraft to get less communication time, as reported by Space News.
- The new antenna, DSS-23, began operations on 3 August 2026, tracking NASA's Chandra X-ray Observatory, per JPL.
- A 2015 NASA Office of Inspector General report estimated the project at €333 million ($362.4m), but by fiscal 2023 costs had risen to €650 million ($706m), according to Space.com.
- Construction of DSS-23 started in February 2020; the 133-tonne reflector framework was placed in December 2024, per JPL.
- The six-antenna Aperture Enhancement Project, begun in 2009, will be completed when DSS-33 comes online in Canberra in 2029, per NASA.
