An illustrative embodiment of the invention includes an apparatus and method for making air and space inflatables and deployables using three dimensionally reinforced (3DR) membranes. A 3DR process preferably takes plural substantially flat gore segments, each segment made of plural membranes and reinforcing fibers, and joins adjacent gores so the seams on opposite sides are offset. Single ply seam tape may be used. When all gores are joined, a three dimensional deployable or inflatable (e.g., balloon) structure with a minimized seam is produced. Further, localized fiber reinforcement may be used, with different characteristics depending on the desired placement in the gore, allowing the substantially flat gores, when joined and loaded, to strain to the desired three dimensional shape. In doing so, the required number of gores and seams may be reduced, while using materials with significantly lower areal densities. Thus, the 3DR process allows one to make locally reinforced materials that optimize strength to weight ratios; permits single ply and sub-gore width seam tapes; permits multi-phase optimized envelope shapes, designed to efficiently handle multiple loading conditions; and provides increased design flexibility for a wide range of shapes and characteristics impractical or unavailable under prior techniques.

An inflatable docking station for a Mars roving vehicle (Mars rover) provides a recharging station as well as a storage facility for the Mars rover during adverse environmental conditions. The docking station / garage allows for extended operational life for the Mars Rover, allows for the Mars rover to operate at the polar regions of Mars, where extreme cold conditions restrict rover operation, and provides for a warmer habitat for the Mars rover. Conventional planetary roving vehicles only be deployed from the warmer equator region of the planet surface. However, these roving vehicles may never explore the polar regions because the roving vehicle may not have enough stored power. The docking station / garage provides a remote outpost for, among other things, storing and recharging the Mars Rover to allow it to reach more remote areas.
