Photos: Looking back at the evolution of human spaceflight

April 12th is the International Day of Human Spaceflight, a day set aside by the United Nations for recognizing the “important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of States and peoples.” It is the anniversary of the first human in space, Soviet cosmonaut Yuri Gagarin, who orbited the earth in 1961.

In the more than 50 years since Gagarin’s flight, the image of space travel has changed tremendously. The coffin-like module filled with a single man has been replaced by the International Space Station, a massive floating laboratory with upwards of a dozen men and women crew members representing multiple countries. Follow the evolution of human spaceflight in the photos below.
