The United Nations General Assembly declared in 1999 that World Space Week (WSW) will be held each year from October 4-10. The dates were in recognition of the October 4, 1957 launch of the first human-made Earth satellite, Sputnik 1, thus opening the way for space exploration and the October 10, 1967 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.
World Space Week is an international celebration of science and technology, and their contribution to the betterment of the human condition. World Space Week aims 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
Foster international cooperation in space outreach and education
"Starry skies are a vanishing treasure because light pollution is washing away our view of the cosmos. It not only threatens astronomy, it disrupts wildlife, and affects human health. The yellow glows over cities and towns — seen so clearly from space — are testament to the billions spent in wasted energy from lighting up the sky. To help raise public awareness of some of the issues pertaining to light pollution, Loch Ness Productions in collaboration with the International Dark-Sky Association has created a 6.5-minute "public service announcement" called Losing the Dark. It introduces and illustrates some of the issues regarding light pollution, and suggests three simple actions people can take to help mitigate it."
