Lunar Cargo Vehicle (LCV).
A space station, such as the International Space Station (ISS) cannot orbit the Earth forever, eventually, the Earth's gravity will pull it down, and it will crash into the Earth's surface. One way to prevent the ISS from impacting the Earth's surface is to disassemble the station, and transport the pieces of the station to the Moon, where the pieces will be soft-landed on the lunar surface, and eventually put together to become a permanent base on the Moon. To do this, you would need a Lunar Cargo Vehicle . One example of what a Lunar Cargo Vehicle (LCV) would look like is shown in the illustrations below.
The illustration above shows what the LCV would look like. The LCV would have a pressurized crew compartment, and several rocket engines to propel it. It would have straps hanging beneath it, so that pieces of the ISS could be held securely.
The illustration above shows the LCV carrying part of the ISS. The ISS module is held securely by the straps underneath the LCV.
The illustration above is a side view that shows an ISS module strapped to the underside of the LCV.
The illustration above shows the LCV carrying part of the ISS through space, on it's way to the Moon.
The illustration above shows the LCV landing on the lunar surface while it carries the module that has been removed from ISS.
The illustration above shows the LCV leaving part of the ISS on the Moon, as if takes off. The LCV can return to the ISS and pick up another module, and bring it to the Moon. Eventually, all the modules from the ISS could be brought to the Moon, and assembled there, to create a permanent lunar base.
Symmetrical Space Shuttle Configuration.
The space shuttles flown by NASA into orbit are not symmetrical , the shuttle vehicle itself rides in a lopsided position on the side of an enormous fuel tank. When it gains altitude after launch, it actually rolls around, so the heavy side is facing Earth. This roll is unavoidable since the Earth's gravity pulls on the shuttle, and reorients it, so it's heaviest side is facing down. A possible answer to the problem is to design a space shuttle that is symmetrical. This design actually has two re-entry vehicles facing each other in a back-to-back configuration. Since the two re-entry modules weigh the same amount, the entire vehicle is naturally balanced. A set of rocket boosters are installed in the gap between the two re-entry vehicles. When the vehicle is launched, the two re-entry vehicles separate from one another and they jettison their rocket boosters when the boosters run out of fuel.
Space Shuttle With Multiple Lunar Modules.This invention combines the concept of a space shuttle (which dates back to the 1980's) with the concept of an Apollo lunar module (which dates back to the 1970's). The space shuttle in this invention would carry as many as four lunar modules into lunar orbit, then the lunar modules would leave the shuttle and would land on the moon.
Zero-Gravity Stereolithography For Forming Interior Walls In An Orbital Vehicle.
An orbital vehicle can be folded up into a very compact package and launched into orbit, and after it has been placed in a zero-gravity orbital environment, it can unfold itself, to make more interior space available. After it is fully unfolded, it can build walls and other partitions inside of itself with a stereolithography apparatus. The stereolithography machine would extrude a liquid plastic that solidifies when laser beams hit it. Walls and furniture can be built inside the orbital vehicle with this method.
