In April 2011, the UN General Assembly adopted resolution 65/271, designating April 12 as the International Day of Human Space Flight, commemorating the launch of Soviet cosmonaut Yuri Gagarin on April 12, 1961, aboard Vostok 1, when he became the first human to orbit the Earth — an achievement that reshaped the course of human space exploration. The day celebrates humanity's scientific and technological progress in space exploration, from the first steps on the Moon to the International Space Station and missions toward Mars and beyond. It also highlights how space technology serves daily life on Earth, from communications and satellites to weather forecasting, climate monitoring, and disaster management. Space agencies, science museums, and schools worldwide mark the day through the global "Yuri's Night" celebrations, along with lectures and hands-on workshops for children and young people, aiming to inspire new generations to pursue science, engineering, and space studies.
