Building blocks for governance of space resource activities
The Hague International Space Resources Governance Working Group announces adoption of the Building Blocks of an International Framework on Space Resource activities
A definition of space settlement
Dale L. Skran of the National Space Society breaks down the term differentiating between individual permanent habitats and the general creation of a grander association of colonies:
“ ‘A space settlement’ refers to a habitation in space or on a celestial body where families live on a permanent basis, and that engages in commercial activity which enables the settlement to grow over time, with the goal of becoming economically and biologically self-sustaining as a part of a larger network of space settlements. ‘Space settlement’ refers to the creation of that larger network of space settlements.”
Determining the Gravity Rx
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.
