Space Studies Institute is a not-for-profit organization that was founded in 1977 by Princeton University Professor Gerard K. O'Neill. In 2009 SSI moved its operations from its long-term base in Princeton, New Jersey, to Mojave, California. SSI is involved in several initiatives, including a solar sail project that it is developing with Carnegie Mellon University and an effort to find asteroids that could be mined for valuable materials. The use of extraterrestrial resources in space settlement has received increasing attention in recent years. More information...
