Around the late 1950s, a species sent a transmission broadcast from the Moon to Earth in their native language offering knowledge and technology to aid the development of humanity. The United States government had hidden this transmission — in the Tenth Doctor's words, the Secret Service had "locked this transmission away in a box for their own ends". This transmission was picked up when Apollo 11 launched into space in 1969. Upon taking over Mission Control, two secret service agents, Spencer and Milledge had intended to use the species' technology against the Russians in the Cold War. The Tenth Doctor attracted their attention with a message on the Moon and told them humanity had to find their own way. The species left, with no trace of them by the time Apollo 11 touched down on the Moon. (PROSE: Blue Moon)
