The National Space Society (NSS) is an independent, educational, grassroots, non-profit organization dedicated to the creation of a spacefaring civilization.
Founded as the National Space Institute (1974) and L5 Society (1975), which merged to form NSS in 1987, The National Space Society is widely acknowledged as the preeminent citizen's voice on space.
NSS has over 10 thousand members and supporters, and over 50 chapters in the United States and around the world. The society also publishes Ad Astra magazine, an award-winning periodical chronicling the most important developments in space.
Each year, NSS sponsors the International Space Development Conference (ISDC), in different cities throughout the United States. ISDC brings together a diverse group of NASA officials, aerospace industry leaders and interested private citizens to engage in discussions about today’s prevalent space issues in order to stimulate innovation and overcome the obstacles that hinder human advancement off the Earth.
For U.S. tax purposes, NSS is a tax-exempt, 501(c)(3) educational, non-profit corporation.
