Countries around the world participate as the Earth turns and during a 24 hour event the Moon is visible to all countries. In amateur circles, the activities are also known as EME (communications)

 (Earth-Moon-Earth). The first World Moon Bounce Day had Apollo astronaut Bill Anders as a guest. His interview was bounced off the moon as part of the activities. The University of Tasmania in Australia with their 26m dish was able to bounce a data signal off the surface of the Moon which was received by a large dish in the Netherlands. The data signal was successfully resolved back to data setting a world record for the lowest power data signal returned from the moon with a transmit power of 3 milliwatts - about 1,000th of the power of a strong flashlight filament globe.

The next World Moon Bounce Day is scheduled for the month preceding Apollo 13's 40th anniversary in March or April 2010.

Echoes of Apollo also provide a news clipping service for space news. Its main focus is on space missions, but also contains interesting astronomy news, especially when associated with radio telescopes. It is updated regularly during the week and can be viewed at: http://echoesofapollo.com/category/space-news/. The website provides significant information about the Apollo program and the communications network that supported the program. (http://www.wia.org.au/members/armag/2009/august/)
