International Space Station program ocean was found to be possible only with Russia's assistance. At the time ISS was launched, the Russian Space Agency had experience from de-orbiting the Salyut 4, 5, 6, and 7 space stations, while NASA's first intentional controlled de-orbit of a satellite (the Compton Gamma Ray Observatory) would not occur for another two years. NASA currently has no spacecraft capable of de-orbiting the ISS at the time of decommissioning. Skylab, the only space station built and launched entirely by the US, decayed from orbit slowly over 5 years, and no attempt was made to de-orbit the station using a deorbital
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.
