Start of World Space Week (October 4), October 4, 1999. This observance marks the beginning of a week dedicated to promoting public awareness about the importance of space science and technology. World Space Week is held annually from October 4 to 10, aiming to increase public engagement and highlight achievements in space exploration. The decision to designate World Space Week was made by the United Nations General Assembly in 1999, which is why it was added to the Gregorian calendar that year. The date was chosen to commemorate the launch of the world’s first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. This event marked a significant milestone in the history of space exploration and signaled the start of the space age. During this week, educational events, exhibitions, and scientific activities are organized in various countries to emphasize the role of space technology in improving human life and supporting sustainable development. World Space Week serves as an opportunity for international cooperation and knowledge exchange among scientists and space enthusiasts.
