Lost

A Cosmonaut who got lost in the depth of the cosmos. 

The Lost Cosmonauts or Phantom Cosmonauts are subjects of a conspiracy theory alleging that Soviet cosmonauts went to outer space before Yuri Gagarin, but their existence has never been publicly acknowledged by either the Soviet or Russian space authorities. The Government of the Soviet Union supposedly suppressed this information, to prevent bad publicity during the height of the Cold War. (Wikipedia)

Imagine one of these Lost Cosmonauts would miraculous return now to the planet earth and could see how the world has changed – would like it what he sees or would he miss the world he left behind?
