A lunar calculation with Almagest
BLUF A momentum-exchange tether in Earth orbit can deliver a payload to the Moon with [] times less fuel than a rocket. The savings multiply when there’s another tether around the Moon to send a payload back, if only for the fact that we do not have to send fuel (mass) for the return trip. I’m developing a simulation tool called Almagest to run tether calculations. Almagest is the foundational piece of software for this tether network, for everything from planning to web-based simulations, even for the embedded systems that will power the tethers themselves. ...
