The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future. The following are a few of the conclusions: -The study used the concept of "constant power" as a baseline because of its ability to lower design requirements on the tether climber. -The mass breakout of 6 MT for a climber and 14 MT for customer payloads seems...

This history of SAFSP is dedicated to all those men and women who fought the Cold War, in silence - from above.
