Goonhilly Earth Station Supports Artemis II Lunar Mission Communications

NASA’s Artemis II mission, scheduled for no earlier than April 2026, will rely on a network of ground stations, including Goonhilly Earth Station in Cornwall, to support communications during its lunar flyby.

The Artemis II mission aims to send four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—on a crewed flight around the Moon. The launch is planned from Launch Complex 39B at Kennedy Space Center in Florida, marking the first human lunar mission since Apollo 17.

Goonhilly Earth Station operates as a commercial facility capable of providing telemetry, tracking, and control for lunar and deep-space missions. The station has previously supported Artemis I by handling communications for CubeSats during the early phases of that mission.

In October 2024, Goonhilly Earth Station signed a contract, backed by the UK Space Agency and other international partners, to deliver communications services for lunar and deep-space projects. This agreement included up to £2 million in funding to enhance its operational capabilities.

What the numbers show

• The Artemis II launch window includes April 1, 3, 4, 5, and 30, 2026
• Goonhilly’s antenna (GHY-6) received an £8.4 million upgrade over two years
• The Artemis II rocket rollout is scheduled around March 19, 2026

NASA completed repairs on the Artemis II Space Launch System rocket, addressing a helium-flow issue and confirming readiness for the April launch window. The rollout to the launch pad is planned for mid-March 2026, following a positive Flight Readiness Review.

The upgraded Goonhilly facility, specifically the GHY-6 antenna, is now equipped to support both robotic and crewed missions to the Moon and Mars. This investment has expanded the station’s role in international space communications infrastructure.

Goonhilly’s involvement in Artemis II builds on its previous experience with deep-space mission support. The station’s capabilities in telemetry, tracking, and command are integral to maintaining communication links during critical mission phases.

The Artemis II mission represents ongoing collaboration between NASA, the UK Space Agency, and other international partners. Ground stations like Goonhilly are positioned to play a continuing role in supporting future lunar and deep-space exploration activities.
