📖 About Space Flight Day

April 12 marks the anniversary of Yuri Gagarin's 1961 flight aboard Vostok 1, the first time a human being traveled into space. The United Nations formally designated April 12 as the International Day of Human Space Flight in 2011, fifty years after the original flight, recognizing the role human spaceflight has played in advancing science and international cooperation.

How It's Observed

Space agencies, museums, and astronomy organizations worldwide hold talks, exhibits, and educational events. In parts of the space community, the date is also informally known as Yuri's Night, marked with celebratory public events at planetariums and space museums.
