Here’s a message from The Society for International Space Cooperation :
The Society for International Space Cooperation (SISC) is an educational nonprofit organization whose board includes astronauts, cosmonauts, and luminaries like director James Cameron. We invite you to join the Space Explorers Club or Junior Space Explorers Club and be sent a different box every month with space goodies and space and science info from the past, present, and future of spaceflight.
The Society for International Space Cooperation is a 501(c)(3) so all donations are 100% tax deductible and all proceeds help support the educational programs of the society.
