On behalf of my fellow Co-Founders Dan Adamo and Dr. John Jurist, welcome to the Space Enterprise Institute website. SEI is a tax-deductible educational and scientific foundation organized under Section 501(c)(3) of the Internal Revenue Code of the United States. We created SEI to provide an important missing element in the overall public space discourse: Evidence-based analysis and synthesis supported by objective verifiable data, documented spaceflight experience and reasonable extrapolation.
