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 (see merger proclamation), NSS is widely acknowledged as the preeminent citizen's voice on space. NSS has over 12 thousand members (and more 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.
For U.S. tax purposes, NSS is a tax-exempt, 501(c)(3) educational, non-profit corporation. All donations to NSS are fully tax deductible (as allowed by your local laws).
NSS' grassroots political activities are governed by the 501(h) election, which permits a limited amount of activity aimed at influencing U.S. legislation.
