Goonhilly Earth Station is an operational commercial satellite ground station on Cornwall’s Lizard Peninsula, with 24/7/365 monitoring and services spanning satellite uplink and broadcast, telemetry tracking and control, gateway and launch-and-early-operations support, Earth observation, radio astronomy and deep-space communications. The site dates to 1962, when its Arthur antenna carried the first live transatlantic television transmission via Telstar; today its GHY-6 32-metre and GHY-3 30-metre antennas support lunar and deep-space links, and the operator says they have been qualified with NASA’s Deep Space Network and ESA’s ESTRACK network. This is privately operated infrastructure rather than a general walk-in attraction: Goonhilly’s current contact page says the former visitor centre closed in 2012 and that public visits cannot currently be arranged, although the operator offers outreach, education and occasional events. Confirm any current programme with the operator and do not enter the operational site without authorization.
