Wet Launch of Prefab Habitat Modules

GEnie Spaceport Library files - Look for ones with "Centristation" as part of their titles

Mid section of sci fi novel "Building Up."

Background: By 1989, the KESTS to GEO concept clearly pointed to - at least in the author's vision - the probablility that large cities of the artificial gravity kind could be economically built in GEO, buy the use of the KESTS transporation system. It seemed prudent to get some real life experience in self-sustaining orbiting city design in Low Earth Orbit, while the KESTS was in R&D. A quick and relatively economical and risk-free technique for building a mile-diameter rotating city in LEO was needed, so the author created and expanded the Centristation concept, short for "Centrifugal Station." This was explored in files he wrote and put on the GEnie Spaceport library, in his pages, and in pages on his websites and domains. And in 1995 the concept became the subject of his first formally peer-reviewed published technical paper at a space conference; which he wrote, prepared as camera ready copy, and presented in person at the Space Studies Institute's space conference at Princeton NJ in 1995, and which was published as part of their proceedings, and was titled "Wet Launch of Prefab Habitat Modules."

Basics: As in the KESTS concept, it is basically simple. Build a mile-diameter wheel-type space station on the ground, composed of, say, 15 foot diameter segments that are designed for dual use, each as both as the habitat module and as its own fuel tank for its launch and orbital emplacement; this is far more efficient as there is little tankage involved, it is all payload. The mile-diamteter wheel shaped self-sustaining facility is integrated and debugged while on the ground, merging the myriad mechanical, electrical, and living systems together. Then take the segments one by one, and using a reusable flyback engine module and booster, launch them into Low Earth Orbit, docking them together in sequence until the spoked wheel is again put together, but this time in orbit, each segment roatated 90ยบ along its radius, so that the internal floor now faces outward on the wheel's perimeter, so that when spun up, artificial gravity will orient properly. The launches would be powered by two flyback modules: the main engine module, and the airbreathing booster module, each of which would then be re-used to launch the next module. When the wheel's modules are all docked into position with each other as a hubbed wheel, the the first manned presence would arive, to remove the internal bulkheads that isolated fuel from oxidizer in each module, install tension loops around the wheel, and then begin the wheel's spin up. The facility would house 200 to 1,000 people, I envisioned. This is a lot of people as compared to the existing International Space Station, but small as compared to the 10,000 people each of the wheel type cities KESTS would enable to be built in high Earth orbit GEO. Of course, the KESTS would also enable easy transportation to orbit for all those people, too. This is also explored in detail in the midsection of my sci fi adventure novel "Building Up."

That said, here are the files and paper I wrote and published on the subject:

And the construction of a Centristation is explored in far more detail (and more entertainingly) in the form of the midsection part of a science fiction adventure novel, titled "Building Up."
