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.”
The Art of Bioneering
In a previous post I mentioned Dr. Jim Logan’s concept for space settlements in a cored out section of Deimos presented at the Bioneering Panel at SSI 50. A string of 10 Island One settlements would be placed in a 15km x 1/2km tunnel bored through the Martian moon. Videos of the Panel have been posted and details of the concept can be found at 1:47:23
EXPAT: Expandable Shielded Rotating Space Habitat
Anthony Longman of Skyframe Research presented his concept for a free space settlement built from Asteroid materials at the Space Studies Institute SSI 50 last September. The system uses a structural design concept called Tensegrity to start small from an 8.5m pressure hull and expand iteratively to progressively larger stages ending with a habitat large enough for 8000 people. The final structure contains 90 acres of managed woodland complete with outdoor mall space and over 5 floors of living quarters. Longman appeared recently on The Space Show to provide further details of the concept. His presentation can be found at timestamp 1:32 into the SSI 50: 01 Habitat Design Presentation.
Destination Deimos – prime real estate for space settlement
At SSI 50, the Space Settlement Enterprise conference sponsored by the Space Studies Institute, I had the pleasure of meeting Dr. Jim Logan, a medical doctor with 22 years experience as a NASA Flight Surgeon where he served as Chief, Flight Medicine and Chief, Medical Operations. Dr. Logan along with former Flight Dynamics Officer Dan Adamo, developed a strong argument in 2014 for Deimos as the ideal destination for initial space outposts. Says Logan, “Deimos, for a number of VERY valid reasons, is the best choice by far for early settlement”. Their paper outlining this concept provides a convincing argument that Deimos is the most valuable piece of real estate in the solar system.
On the last day of the conference Dr. Logan presented an innovative concept for a string of O’Neill type settlements constructed in a tunnel bored straight through Deimos. The architecture addresses the problem of radiation protection and delivers Earth normal gravity while providing an easy to get to platform for telerobotic exploration of Mars. Videos of this presentation will be coming soon on the SSI YouTube Channel.
Logan and Adamo are co-founders of the Space Enterprise Institute, which provides evidence-based research inspiring expansion of human activity in space.
