Submission + - NASA Study Shows Faster, Cheaper Alternative to SL (spaceref.com)

Larson2042 writes: The site SpaceRef has an article about how an internal NASA study provides a cheaper and faster way to get humans beyond low earth orbit:
"This presentation "Propellant Depot Requirements Study — Status Report — HAT Technical Interchange Meeting — July 21, 2011" is a distilled version of a study buried deep inside of NASA. The study compared and contrasted an SLS/SEP architecture with one based on propellant depots for human lunar and asteroid missions. Not only was the fuel depot mission architecture shown to be less expensive, fitting within expected budgets, it also gets humans beyond low Earth orbit a decade before the SLS architecture could."
