Eddy, and 6 co-authors, reported in 2019 that reliable, routine, safe, and efficient access to space is close at hand. The Space Elevator is the Galactic Harbour, and an essential part of the global and interplanetary transportation infrastructure. In the community of off-planet movement with NASA's newest move to put boots on the Moon by 2024, space elevators must be tossed into the discussions. The key here is that daily, routine, inexpensive, massive movement of payloads to GEO and release from over locations on the Space Elevator will allow high speed launches to other bodies in our solar system.
This study will start the discussions about the strengths the space elevator has for supplying activities such as: factories, mining, distribution GEO satellites and other activities that can done easier in a weightless environment. The reality is that when humanity decides to do off planet activities, there will be a tremendous need for logistics support, movement of manufactured goods as well as transporting people [especially at low cost and routine/daily]. The question on ISEC's table is: how can the strengths of the space elevator enable missions of all types, while having little or no environmental effect on our planet? The authors conclude that not only can it do this but also allow activities in space that will improve Earth’s environment. This study hopes to show what the environmental effects of building and daily use of space elevators will be and what kind of activities can be done to improve the Earth’s environment.
