Reusable NewSpace: Earth Orbit Station, Part II [1] ['This Content Is Not Subject To Review Daily Kos Staff Prior To Publication.'] Date: 2024-07-26 "The Earth is a beautiful planet. The space station is a great vantage point to observe it and share our planet in pictures. It makes you more of an environmentalist." – NASA Astronaut Scott Kelly Kindly Note: This is a Daily Kos Series on a technical paper that I recently completed.

TABLE OF CONTENTS =<<>>= EOS PART I EOS UPPER LEVEL Image 1: EOS Upper Level side view The Upper Level is focused on the topmost Doublewides and its attachments (Images 1) [Larger Image]. Two horizontal Singlewides will be used as Observation ports on either side. The Singlewides will have wide windows on one side of the module to allow for spectacular views. Hanging underneath the lateral Doublewide is an observation port modeled after the Crew Module. All three EC/LSS units are located in the top deck with no windows. This allows the other two decks to have windows in all directions. Like the CM, this module will not be "hardened" because of the windows. :: INVENTORY UNIT UNIT MASS UNITS TOTAL UNIT MASS RV FLIGHTS Doublewide 21,000 kg 3 63,000 kg 3.00 Singlewide 10,500 kg 4 42,000 kg 2.00 Connector 2,625 kg 2 5,250 kg 0.25 3–Level Observation 5,250 kg 1 5,250 kg 2.25 Total Mass 115,500 kg 5.50 =<<>>= EOS LOWER LEVEL Image 2: EOS Lower Level top view This section is where all of the Berthing modules will be located. Horizontal Half–Singlewides will jut out from either side of the horizontal Doublewide. Two other horizontal Singlewides will be attached on either side of the vertical Doublewides as observation ports. As viewed from the top (Image 2) [Larger Image], we can better see the berthing layout. The horizontal Half–Singlewides act as a spine to hold the vertical Singlewides and Half–Singlewides. If we take Image 2 and pitch down, you get Image 3 [Larger Image]. Image 3: EOS Lower Level side view This image shows how the berthing modules are attached on the top and bottom using a Connector. The modules attached to the top are used by the crew, whilst the bottom modules are used by tourists. The Half–Singlewides attached on either end are for senior officers. CM_3 Crew Modules with 12 EVA ports will be attached underneath the lower Singlewides, only these CMs do not go anywhere and thus have no flight controls. This will allow tourists to experience the thrill of going outside on spacewalks. :: INVENTORY UNIT UNIT MASS UNITS TOTAL UNIT MASS RV FLIGHTS Doublewide 21,000 kg 3 63,000 kg 3.00 Singlewide 10,500 kg 24 252,000 kg 12.00 Half–Singlewide 5,250 kg 8 42,000 kg 2.00 Connector 2,625 kg 28 73,500 kg 3.50 CM_3 EVA Module 5,250 kg 8 42,000 kg 2.00 Total Mass 472,500 kg 22.50 =<<>>= RESUPPLY MODULE Since the dawn of time, explorers have always had to carry their provisions everywhere they went. Twenty–first century explorers are no different. Image 4: Resupply Module Our Resupply Module will be based on the single–level Crew Module design, with a pressurized hatch on the bottom of the module (Image 4) [Larger Image]. There are no windows or controls. The module will be docked with the Connector located between the Berthing Modules. The crew enters the module through the hatch and offloads the supplies. Once empty, the module becomes a garbage collector where dirty laundry, food trays, and other waste products are stored for the trip home. Most items will be washed and reused. The static mass of the module is displayed in the Table below. ITEM MASS Unpressurized Docking Ring 48 kg Outer Top Deck 16 kg Structure 1,049 kg Electrical Power 59 kg Communications 148 kg Instrumentation 85 kg Misc. Equipment 36 kg Floor 7 kg Outer Bottom Deck 16 kg Pressurized Docking Ring 80 kg Resupply Module Static Mass 1,275 kg Our Resupply Module will be able to feed and clothe 48 individuals for 46 days (if it were a Crew Module, it would be designated as a CM1_48–00–46). Cargo containers will carry all the various items needed for a functioning station (Table below).

There are three sections to the Bottom Level (Image 5) [Larger Image]. The VentureStar docks on either end of the top part, which is comprised of docking ports, two observation singlewides, and one observation Half–Singlewide. Underneath the top level is a vertical Singlewide Observation module and horizontal Singlewide Observation modules attached at right angles. This will provide spectacular views of spacecraft docking and undocking. The second level is a unique Singlewide that has three ECLSS units on the top and bottom decks, allowing for 360–degree views from the middle four decks. :: INVENTORY UNIT UNIT MASS UNITS TOTAL UNIT MASS RV FLIGHTS Singlewide 10,500 kg 5 52,500 kg 2.50 Half–Singlewide 5,250 kg 1 5,250 kg 0.25 Connector 2,625 kg 6 15,750 kg 0.75 Spaceliner Docking 2,625 kg 2 5,250 kg 0.25 6–Level Observation 10,500 kg 1 10,500 kg 0.50 Total Mass 89,250 kg 4.25 =<<>>= EOS POWERPLANT (TOP LEVEL) Image 6: EOS Powerplant Modules and accessories Electric power will be provided to our space station via a system of solar panels and associated hardware (Image 6) [Larger Image]. The solar panels will be folded into a singlewide Orbital Solar Power Module (OSPM). Other modules will be used to rotate the OSPM so that the panels remain orthogonal to the sun. This includes rotations in the pitch and yaw axes. Each panel measures 3.74 m by 13.11 m, or 49.02 m2. The six extended solar panels produce an area 294.10 m2. Each OSPM solar panel package will generate 48 kW of electricity, which is enough to provide 20 kWh of continuous power. Image 7: EOS Powerplant Radiators for space station waste heat will be attached at a right angle to the solar panels, ensuring that the radiators remain in perpetual shadow. Sixteen OSPMs will be attached to the rotation modules (Image 7) [Larger Image], providing the space station with 320 kWh of continuous electric power. The solar facility will be mounted at the Top Level, above the EOS Upper Level. The central rotation modules will be attached to the top of the lateral Doublewide. :: INVENTORY [END] --- [1] Url: https://www.dailykos.com/stories/2024/7/26/2244129/-Reusable-NewSpace-Earth-Orbit-Station-Part-II?pm_campaign=front_page&pm_source=more_community&pm_medium=web Published and (C) by Daily Kos Content appears here under this condition or license: Site content may be used for any purpose without permission unless otherwise specified. via Magical.Fish Gopher News Feeds: gopher://magical.fish/1/feeds/news/dailykos/
