A detailed design for a space station at sun–Earth L2

New concepts in space exploration come from all corners, and, by and enormous, the group welcomes anyone within the subject. Having simply learn “A Metropolis on Mars,” evidently even individuals who disagree with the concept the age of space settlement is imminent shall be accepted into the fold by fans. Now, a brand new entrant has joined—Daniel Akinwumi is a Nigerian graduate pupil on the College of Strathclyde who lately posted his master’s thesis to ResearchGate detailing the design of the “intergalactic hub,” or I-HUB.

The introductory part of the thesis lays out most of the challenges acquainted to these considering space habitats. These embody the significance of robots, a very closed-loop recycling system, and novel radiation shielding. Mr. Akinwumi additionally offers a radical literature search and mentions a number of different design ideas much like the I-HUB.

One essential design alternative is get the system into space. As of the time of writing, I-HUB will use Starship, the most important rocket ever developed, which remains to be being examined. Lots of the different chosen methods for the I-HUB would make the most of applied sciences developed elsewhere, equivalent to NASA’s ECLSS life assist system or customary RTGs for an influence supply.

Meals is important for any long-term habitat, and the paper seems to be carefully at completely different food-production methods to be used in space. NASA’s Vegetable Manufacturing System is without doubt one of the most extremely developed and may very well be used on the I-HUB with little modification. Propulsion is one other key system, with I-HUB being designed behind an in depth solar electrical propulsion system that will permit 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 chance. Any such meeting would additionally need to 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 location may very well 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 is not to stay static however to proceed to develop by including further modules over time to extend each its bodily and operational capability. Modular designs of the modules that will join can be important to this function and can be much like how the completely different modules join on the ISS.

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

Mr. Akinwumi additionally detailed budgets for numerous methods, equivalent to energy and mass, and the anticipated general value of the station. In his evaluation, he fleshed out among the inherent dangers within the system and detailed how they may very well be mitigated with future improvement work. A few of these would come with a number of redundancies of the life-support methods and numerous layers of radiation shielding.

General, the plan for I-HUB appears cheap and weighs in at a hefty 71 pages—in all probability just a little above common for an MS thesis. Nevertheless, these pages have few new ideation particulars; it is extra a group of concepts already detailed in different sources and in rather more element than even this thesis would permit. It is a good begin on a promising analysis line, and hopefully, Mr. Akinwumi will proceed together with his Ph.D. and may delve additional into the small print of his I-HUB thought.
