Space, the final frontier.

Forty six years ago today Yuri Gagarin became the first man to fly in space and orbit the Earth. Twenty six years ago today Columbia became the first shuttle to fly in space. Ironically, Gagarin was working on designs for a reusable space vehicle prior to his death. What started out as an expansion of the Cold War has evolved into former enemies "sitting in a tin can high above the world" together and people celebrating Yuri's Night every year.
