The European Space Agency (ESA) played a crucial role in supporting India's Chandrayaan-3 mission by providing deep space communication support. ESA's ground stations in Kourou, French Guiana, and Goonhilly Earth Station Ltd in the UK, along with NASA's Deep Space Network and ISRO's own stations, were used to track, command, and receive data from the Chandrayaan-3 spacecraft. ESA's 35-meter antenna in New Norcia, Australia, provided additional tracking support during the lunar landing, serving as a backup for ISRO's own ground station. This backup support was essential during the critical moments of the landing, as it ultimately helped confirm the success of the landing by providing vital telemetry data.
