TO SPACE, TOGETHER
We are building a decentralized space program, connecting thousands of engineers, scientists, and future astronauts, to devise and fund next-generation space initiatives.
Let's discuss the formation of a team to participate in International Competition in Architecture 2018 (http://www.fondation-jacques-rougerie.com/competititon-in-architecture/) Feel free to counter my proposals below. Basics: Theme: LUNAR VILLAGE Deadline: November 19, 2018 at 11:59 PM GMT - 2 months from today (sep/14th!) Rules: https://www.wiin-project.com/extras/competitions/internationalcompetitioninarchitecture2018.brief.en.5203.WiiN-Project.com.pdf Proposal: What: Develop a concept for a Habitat/Village using lunar ISRU. How: Using the Coral mission as a DRM - but not limited to it. Why: To demonstrate a long-term application for Coral and produce a possible vision of our ultimate objective. Logistics: Seeing as there are only 2 months left, this will have to be sort of a sprint project, Weekly meetings with a tightly managed schedule and weekly turnouts, Max of 10 people on the team, What do people think, and who would like to participate?
Inflatables offer unique benefits for initial habitats. Their construction can be done on Earth where all materials, expertise, and testing is readily available. They can use high-strength material such as Kevlar. They can be packaged tightly within a payload yet expand to very large volumes. Furthermore, they use very little energy to set up on the Moon, breakdowns during construction are unlikely, they don’t require the mining and processing of materials such as binders for 3D-printed habs, and set-up time could be done in an afternoon simply by opening a valve on a tank of condensed air. The Space Development Network proposes an initial lunar habitat called the UniHab. It is pancake-shaped with a roof held flat via internal, 1 cm diameter tethers every 3 meters. Think of an air mattress. The roof is flat so that telerobots can push unconsolidated regolith on top which won’t slough off. About 11 cm of regolith is needed to protect against solar particle events thus protecting the crew who maintain the telerobots which then continuously push more regolith on top until full radiation protection is achieved. The air pressure is far more than adequate to push up the weight of the regolith on the roof. 35% of the internal volume is allocated for a hydroponic greenhouse providing for all of the caloric and air & water processing needs of an initial crew of eight. Space is also allocated for an indoor centrifuge, living, and working areas. Later inflatables could be delivered on landers using an approach whereby the outermost layer (the abrasion-resistant layer is delivered first with subsequent inner layers delivered and brought in through an airlock. In this way, the maximum, unified footprint can be achieved. For a 20-tonne payload, that comes to about 3.5 acres. So the design of internal spaces is wide open — housing, utilities, garden, recreation, etc.
Space related products that provide services in applications ranging from telecommunications, Earth observation, monitoring and navigation are a fundamental element to our modern way of life. The space industry is confronted with the challenge of sustaining space flight both from an economical prospective, and from environmental hazards created as a result of increased junk in space. This junk has been created by human space endeavours and consists of rocket jettisons, de-functional satellites and small debris emerging from collisions between other satellites and human made space objects. The environmental issue is creating an unsafe condition for space flight, where the risk of collision is increasing; making mission failures more likely. Also with current orbital slots taken up by existing systems and new emerging systems, sustaining space missions becomes a challenge as orbital slots become unavailable for future missions. Space flight is also very expensive that usually involves large upfront costs and government subsidies. This becomes even more complicated because the risk is very high, as currently satellites cannot be recovered or repaired if failure occurs. Failure of a space mission leads to an increase in uncontrolled junk and further costs of developing a new satellite to complete the mission objective. Also when a satellite has completed its mission lifespan, there is no way to salvage or upgrade the existing system. Instead satellite operators find themselves decommissioning existing satellites and developing new ones to provide further services to their customers, which again leads to further costs. To sustain space flight and make it more safe, on-orbit services are being recommended and developed to remove debris, de-orbit existing satellites and extend the life of existing systems through repair and maintenance. When repairing satellites, especially the internal systems such as on board computers, communication payloads, tanks and valves, harness and other internal subsystem components becomes a real challenge. This is because the internal components are shielded from the harsh environment of space through the external structure. Moreover removing panels and holding them in place whilst removing other subsystems to get to the target subsystem, makes the task far more complex. Therefore we propose the use of minimally invasive robotic payloads that utilise miniaturised flexible actuators, which are inserted into the target satellite through a small incision. I'm currently working on a white paper that will address technology requirments and potentail robotic payloads to be integrated to space bus manufacturers and on-orbit service companies such as Astroascale or SLL. The concept of operation aims to utilisie the ISS and work with Made in Space for on-orbit construction of compnents such as sensors, computers and other systems. We will work in collaboration with satelittle manufactruers and aim to spin in flexible robotics technology utilised for laproscopic surgery. This will ensure rapid time to delivery. I'm looking for collaboration and like minded people to work with me on this porject. I'm currently doing all systems engineering work, which involves determing mision concept, objectives, requirments and configuration concept. I look forward to hearing back from like minded people to join me on this exciting journey.
Andy sent me this Mars Habitat Concept (https://actu.epfl.ch/news/scientists-sketch-out-the-foundations-of-a-colony-/), which I had not seen before. It differs a lot from ous but it has one characteristic that we´ve discussed before - the concept of having a pressurized module inside of a protective cover. In this case, their protective dome is also pressurized, and that has a lot of advantages. What are some other similarities with our embryo concept?

For those who don’t know, the plasma magnet sail is a type of magnetic sail invented by John Slough, which should be able to produce orders of magnitude more thrust than ion drives of similar power consumption. It has been tested in laboratory vacuum chambers, but not in space, which is important, since it relies on large-scale space plasma phenomena to work. The device itself is just a set of magnet coils and an RF power supply, which drive large ring currents in the surrounding plasma that generate a magnetic field which defects the solar wind. In principle, it could accelerate a spacecraft up to solar wind velocity of roughly 450km/s, and could create drag in the ionospheres or magnetospheres of planets to enter in capture orbits around them. This seems to be the most recent paper on the subject (http://erps.spacegrant.org/uploads/images/images/iepc_articledownload_1988-2007/2007index/IEPC-2007-015.pdf) If this technology can be miniaturized down to a cubesat level, (I think it can but it would take a PIC plasma simulation to be sure) a cubesat could accelerate to tens of kilometers per second in a few weeks, making it the fastest object ever launched by humans. Desired skill set: Electrical engineering, Cubesat design and construction, Space plasma modeling
The Space Decentral Way
- Initial collaboration is fostered through the community-driven curation of a portfolio of projects
- Requirements and goals are defined for the projects in order to guide the solution stage
- Community members are incentivized to submit open-source action plans through a competitive “request for proposals” process
- Action plans are vetted using a transparent decision-making process
- The best proposal for each project will be added to a digital commons, with alternates archived
- Everyone will have access to these shared commons and will be enabled to take action
- Funds are collectively raised to support the development, testing, and launch of top action plans
- Jobs are created and work contracts are assigned based on solution proposals
- Collaborative research and shared visions become realities
- Contributions are rewarded upon commercial adoption of solutions seeded from the digital commons
