The occasion marks the anniversary of the first human space flight by Yuri Gagarin (USSR).
On this very date back in 1961, Yuri Gagarin carried out the first human space flight. It was a very significant event, paving way for further space exploration for the benefit of all mankind.
Hence, in 2011, the United Nations General Assembly recognized the 50th anniversary of the event and declared April 12 as the International Day of Human Space Flight. The resolution called it a day "to celebrate each year at the international level the beginning of the space era for mankind, reaffirming the important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of States and peoples, as well as ensuring the realization of their aspiration to maintain outer space for peaceful purposes."
Since then, April 12 each year is celebrated as The International Day of Human Space Flight across the world.
