If the nation is serious about the manned exploration and development of space, then more attention must be focused now on research to study how weightlessness and reduced gravity would affect everything from power production to plumbing. The research is critical for the development of space-related technologies. There are certain scientific and engineering problems of a fundamental nature that need to be addressed before these technologies can be developed. This research should be done now …

…will have to build structures and operate mining and processing facilities. Many technologies will be needed for the very survival of humans in space. If an electrical fire starts, how do you extinguish it? It may not be possible to spray it with a fire extinguisher because it may affect the environment in which the astronauts are living and breathing. The particles, very fine droplets, behave differently in gravitational environments than they do in space.
