The idea of making a home in space is rapidly shifting from possibility to reality.
That vision is at the heart of this year's World Space Week (WSW), celebrated annually from Oct. 4 to Oct. 10, with the 2025 theme: "Living in Space." First established by the United Nations in 1999, WSW has grown into the largest annual space event on Earth, marked by thousands of activities across more than 90 countries. The celebration not only highlights current topics in the space industry but also commemorates two milestones in history: The launch of Sputnik 1 on Oct. 4, 1957, and the signing of the Outer Space Treaty on Oct. 10, 1967.
