A Detailed Design for a Space Station at Sun-Earth L2

New concepts in area exploration come from all corners, and, by and enormous, the group welcomes anyone within the discipline. Having simply learn A Metropolis on Mars, evidently even individuals who disagree with the concept the age of area settlement is imminent shall be accepted into the fold by fans. Now, a brand new entrant has joined – Daniel Akinwumi is a Nigerian graduate scholar on the College of Strathclyde who not too long ago printed his Grasp’s thesis detailing the design of the “intergalactic hub,” or I-HUB.

The introductory part of the thesis lays out lots of the challenges acquainted to these involved in area habitats. These embody the significance of robots, a totally closed-loop recycling system, and novel radiation shielding. Mr. Akinwumi additionally supplies a radical literature search and mentions a number of different design ideas just like the I-HUB.

One essential design selection is tips on how to get the system into area. As of the time of writing, I-HUB will use Starship, the biggest rocket ever developed, which remains to be being examined. Lots of the different chosen techniques for the I-HUB would make the most of applied sciences developed elsewhere, similar to NASA’s ECLSS life help system or commonplace RTGs for an influence supply.

We beforehand mentioned an thought to show an asteroid into a large rotating area habitat.

Meals is important for any long-term habitat, and the paper appears to be like carefully at completely different food-production techniques to be used in area. NASA’s Vegetable Manufacturing System is among the most extremely developed and could possibly be used on the I-HUB with little modification. Propulsion is one other key system, with I-HUB being designed behind an intensive photo voltaic electrical propulsion system that will enable it to analysis its deep-space vacation spot of the Earth/Solar L2 level.

Ideally, the system can be inbuilt order, however loads of work on robotic assemblers should happen earlier than that shall be a risk. Any such meeting would additionally must happen close to Earth, as sending a military of assemblers to the L2 level can be prohibitively costly. However the views from L2 can be spectacular, because the paper factors out the positioning could possibly be a useful platform for scientific inquiry – it already homes a number of large-scale telescopes, together with Euclid.

As soon as put in, the intent of I-HUB isn’t to stay static however to proceed to develop by including extra modules over time to extend each its bodily and operational capability. Modular designs of the modules that will join can be crucial to this characteristic and can be just like how the completely different modules join on the ISS.

Among the modules would possibly even rotate to lower microgravity’s dangerous results on the long-term well being of I-HUB’s residents. It would even have an built-in communication system and, as talked about above, a closed-looped useful resource recycling/life help system. 

Mr. Akinwumi additionally detailed budgets for varied techniques, similar to energy and mass, and the anticipated total price of the station. In his evaluation, he fleshed out a number of the inherent dangers within the system and detailed how they could possibly be mitigated with future improvement work. A few of these would come with a number of redundancies of the life-support techniques and varied layers of radiation shielding. 

Total, the plan for I-HUB appears cheap and weighs in at a hefty 71 pages – most likely a bit of above common for an MS thesis. Nonetheless, these pages have little new ideation particulars; it’s extra a set of concepts already detailed in different assets and in far more element than even this thesis would enable. It’s an excellent begin on a promising analysis line, and hopefully, Mr. Akinwumi will proceed along with his PhD and might delve additional into the small print of his I-HUB thought.
