International Day for Human Space Flight – April 12, 2025

International Day for Human Space Flight takes place across the world on April 12. The day celebrates the first space flight and the first human being in space — the great Soviet cosmonaut, Yuri Gagarin. This historic event opened up experiences for humanity like never before. Following Gagarin’s flight to space, there was a renewed enthusiasm for the study of spaces and the cosmos. The day also celebrates humankind’s remarkable progress in building a sustainable relationship with space and using the knowledge for the betterment of every inhabitant of our planet. International Day for Human Space Flight is a celebration of scientific temperament.

History of International Day for Human Space Flight

On April 12, 1961, the world as we knew it changed forever. It was on this date that the first human space flight took off with Yuri Gagarin in it. What a remarkable day for human innovation and perseverance! This event was a pioneer in making the way for space exploration that would benefit all humanity. After Gagarin’s flight, the United Nations General Assembly realized that all of humankind shared a common interest in promoting and expanding the study and use of outer space.

But years before humans would make their way to space, on October 4, 1957, the first human-made satellite — Sputnik I — was launched into outer space. One can agree that this event opened the way for space exploration and possibly sowed seeds for human visits, too. On April 12, 1961, Gagarin became the first human to orbit the Earth — this was a remarkable achievement that occurred only a few years after humans began to study space using modern technology.

Years later, after Gagarin’s space trip, the UNGA described the trip as an “amazing history of human presence in outer space and the remarkable achievements since the first human spaceflight.” At this point, it must be noted that only two years later, the Soviet Union sent Valentina Tereshkova into space, thus making her the first woman to orbit the Earth. Only seven years from then, Neil Armstrong became the first human to land upon the surface of the moon in July 1969. And in July 1975, the U.S. and the Soviet Union launched the first international human mission in space — docking the Apollo and Soyuz spacecraft together. In only a span of 15 years, humankind made progress in space exploration unlike ever before.
