Space Spin-Offs hosted by Neil DeGrasse Tyson

Description:
Technology tuned to the stars, brought down to Earth. Learn about the many products in our lives that were developed because of the space program. Space is now big business. Technology originally developed for the space program sometimes ends up in products foruse on Earth, often in surprising ways. The 40,000 certified "Space Products" range from mattresses to medical devices, and have turned space into a multi-billion-dollar industry. Inspired by our excursions into the Final Frontier, entrepreneurs and inventors are turning stardust into gold.
