World Space Week is an international celebration of 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 to 10.
The dates commemorate the launch of the first human-made Earth satellite, Sputnik 1, thus opening the way for space exploration on October 4, 1957, and 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 on October 10, 1967.
World Space Week consists of space education and outreach events held by space agencies, aerospace companies, schools, planetariums, museums, and astronomy clubs around the world in a common timeframe. These synchronized space events attract greater public and media attention.
The week is coordinated by the United Nations with the support of the World Space Week Association (WSWA). The WSWA leads a global team of National Coordinators, who promote the celebration of World Space Week within their own countries.
The goals of World Space Week are to provide unique leverage in space outreach and education, 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, excite young people about science, technology, engineering, and math and foster international cooperation in space outreach and education.
Anyone can register an event and post it on the WSWA site. This is yet another avenue to advertise planetariums around the world and to a possibly newer audience.
