Buzz Aldrin holds three patents.

Aldrin has received three patents from the USPTO: one in 1993 for a home-designed space station facility that could house eight to ten astronauts; one each in 2003 and 2004 for "flyback boosters with removable rocket propulsion modules" and "multi-crew modules for space flight." Multi-crew spacecraft modules: A launch vehicle is part of an orbital human space launch system. Different crew modules are installed separately in respect to the launch vehicle. Around the launch vehicle's perimeter, the several crew modules are nestled. In addition or alternatively, there are numerous independent crew modules arranged in a pod that is roughly oriented along the length of the launch vehicle. The numerous crew modules are launched using a single rocket. From orbit, each crew module makes a separate trip back to Earth.

With a detachable rocket propulsion module, a flyback booster Several space launch vehicles using variations of the flyback booster (200), which consists of an aircraft (203) housing a launch vehicle stage as a detachable rocket propulsion module (502) are described. A multistage space launch vehicle's first stage is this flyback booster (number 200). To reduce the cost of launch for a particular payload, the stage employed in the flyback booster (200) and the upper stages of the multistage space launch vehicle (213) are chosen.

A space station facility is one that has numerous elongated pieces that come together to form a cuboctahedral-shaped structure that is centered around a pressurized command module. The space station facility may be utilized independently of another space station or in orbit as a space station. Eight tetrahedral-shaped modules or berthing spaces and six pyramidal-shaped modules or berthing spaces are created using the elongated components, which are all of equal length. The fourteen berthing spaces allow access to berthing ports on the central command module. The elongated members may include hinges at their midpoints to make it easier to transport them in a space shuttle's cargo bay and to deploy them in space during the construction of the space station facility.
