World Space Party - Yuri's Night

Yuri's Night is an international celebration held on April 12 every year to commemorate space exploration milestones. The event is named for the first human to launch into space, Yuri Gagarin, who flew the Vostok 1 spaceship on April 12, 1961. The launch of STS-1, the first Space Shuttle mission, is also honored, as it was launched 20 years to the day of Vostok 1 on April 12, 1981. In 2013, Yuri's Night was celebrated at over 350 events in 57 countries.
The goal of Yuri's Night is to increase public interest in space exploration and to inspire a new generation of explorers. Driven by space-inspired artistic expression and culminating in a worldwide network of annual celebrations and educational events, Yuri's Night creates a global community of young people committed to shaping the future of space exploration while developing responsible leaders and innovators with a global perspective. These global events are a showcase for elements of culture that embrace space including music, dance, fashion, and art.

Yuri's Night was created by Loretta Hidalgo, George T. Whitesides and Trish Garner. The first Yuri's Night was held on April 12, 2001, on the 40th anniversary of human spaceflight. This global celebration was preceded by Cosmonautics Day, which was established in the Soviet Union in 1962.
