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
At last: a plan for demonstration of space solar power technology
Stars and Stripes reports that the Air Force Research Laboratory in partnership with Northrop Grumman is planning a Space Solar Power Incremental Demonstration. No word on when flight hardware will be ready, but this is the first initiative of which I am aware that actual space technology demonstration is in the works.
Although the project’s primary objectives are intended to augment military operations with beamed power from space to remote bases, the technology has potential commercial applications as a power source for isolated communities worldwide.
A proposed solution for space debris removal
Maritime traditions can be used as a model for creation of a space salvage entity that would incentivize private contractors to remove orbital debris via a credit based system.
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.”
IKEA is making Mars feel like home
The Swedish furniture company is proactively planning on how to design Martian habitats for comfortable living.
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.
Elon Musk vs. Planetary Protection
If humanity is to settle Mars, with Elon Musk leading the way, the issue of biological contamination of the planet’s surface by humans will need to be resolved in the context of the Outer Space Treaty. This article presents a reasonable compromise proposing a system of three zones partitioned for science, habitation, and resource utilization. This approach minimizes contamination while providing for scientific exploration and Musk’s settlements.
Fill er’ up! Orbit Fab scores $3 million in seed round financing.
TechCrunch reports that the startup gets an infusion of cash fueling its growth. The young satellite refueling company has demonstrated their technology on the ISS and is working with satellite manufacturers to incorporate their standard nozzles on board to enable propellant transfer by robotic refuelers, extending the life of the spacecraft.
