About World Space Week Celebration

World Space Week (WSW) is an international celebration of space science and technology, and their contribution to the betterment of the human condition. The United Nations General Assembly declared in 1999 that World Space Week will be held each year from October 4-10. These dates commemorate two events:

October 4, 1957: Launch of the first human-made Earth satellite, Sputnik 1, thus, opening the way for space exploration.

October 10, 1967: The signing of the Treaty on Principles Governing the Activities of States in the Exploration and Peaceful Uses of Outer Space, including the Moon and Other Celestial Bodies.

WSW is open to all; Government agencies, industry, non-profit organizations, teachers and individuals can organize events to celebrate World Space Week.


  • Educate people around the world about the benefits that they receive from space
  • Encourage greater use of space for sustainable economic development
  • Demonstrate public support for space programs
  • Motivate young people about space science
  • Foster international cooperation in space outreach and education


The WSW is coordinated by United Nations with the support of World Space Week Association (WSWA). The WSWA leads a global team of National Coordinators, who organize events within their own countries.
