International Space Station program with on-orbit refurbishment in mind. According to the Outer Space Treaty the United States is legally responsible for all modules it has launched. In ISS planning, NASA examined options including returning the station to Earth via shuttle missions (deemed too expensive, as the station(USOS) is not designed for disassembly and this would require at least 27 shuttle missions), natural orbital decay with random reentry similar to Skylab, boosting the station to a higher altitude (which would simply delay reentry) and a controlled targeted de-orbit to a remote ocean area. The technical feasibility of a controlled targeted deorbit into a remote
Men into Space spacecraft landings on a desert runway. The distinctive design of the North American X-10 (different from the close up depictions of the series spacecraft) can be seen in the desert landing sequences. "Men Into Space" used for its plots many technical and human problems anticipated by engineers and planners. For example, the show depicted attempts to refuel spacecraft by tanker in orbit, construction of a space telescope, an experiment to dispose of high level atomic waste by launching it into the Sun, the search for life-sustaining frozen Lunar water, and exploration and destruction of an asteroid whose orbit threatened Earth.
