Telescopic view of the whole Moon seen from Earth

Did you know that...

The first communications satellite was the Moon. US Army engineers bounced signals off the Moon in 1951. They did so again in 1955, during a communications blackout caused by a solar storm.

Two of the first artificial communications satellites were large, shiny balloons that reflected radio signals. They were called Echo 1 and 2.
