The Space Elevator by John Sylvain6/28/2023 We have labeled the first as the Initial Operational Capability with the latter Full Operational Capability. The report laid out the numbers that have developed over the last 20 years-from Brad Edwards and early ISEC discussions of 20 tonne climbers with 14 tonne payloads (solidified in the IAA 2019 report) to the Obayashi design of 100 tonne climbers with 79 tonnes of payload on each. The general concept is two Space Elevators per Galactic Harbour with three of those spread around the world. No one asks off planet advocates the really hard question “How much mass is required from Earth?” In our 2020 study report “Space Elevators are the Transportation Story of the 21st Century,” we laid out the movement of mass and our vision for commercial competitively developed space elevators. As we are preparing for our virtual conference (19-20 Aug) and activities surrounding the International Astronautical Congress (18-22 Sept), I have come to realize the basic strength of Space Elevators has not been presented well.
