Joe Carroll of Tethers Applications, Inc. delivered a presentation on a proposal for a LEO partial gravity test facility at the StarShip Congress which took place in San Diego September 13 – 15. An interesting fact is that of all the surfaces of bodies in the solar system where humans may want to build settlements, all of them have gravity similar to the Moon and Mars. Thus gravity in the solar system is “quantized” to just these two levels simplifying the testing regime. Determining the prescription needed for human health in partial gravity is a critical path research topic needed for space settlement.
Satellite servicing database
An Earth orbit service and supply industry is emerging to deliver propellant, components, and repairs, as well as the ability to transfer satellites between different orbits. SpaceFund has established a database of the companies providing these services. Potential investors can view the database here .
