On 27 June 2009, Christian Monstein, our volunteer Regional Coordinator for Switzerland, marked the twentieth anniversary of the Ricken Süd radio observatory by using this ten-meter dish to bounce microwave signals off the surface of the Moon, as part of the Echoes of Apollo activities celebrating the 40th anniversary of the Apollo 11 Moon landing.

In June 2009, the Ricken Süd radio observatory activated their ten-meter dish under the callsign HB9MOON, as part of the Echoes of Apollo activities. They invited children and their parents from the local villages to observe how communication worked 40 years ago while Apollo 11 was landing on the moon. Communication was a very important aspect during the whole mission. Under supervising of eight ham radio operators, the children were allowed to talk with other hams in Australia, Japan, Russia, Netherlands and America. HB9SCT photo
