    Asteroid mining for space uses could be more practical, as transporting materials from Earth is costly. Similar to current plans of reusing the modules of the International Space Station in other missions, an iron meteorite could be used to build space craft in space. NASA has put forward preliminary plans to build a space ship in space. [26]

    For example, cosmic dust can drive the mass loss when a star is nearing the end of its life, play a part in the early stages of star formation, and form planets. In the Solar System, dust plays a major role in the zodiacal light, Saturn's B Ring spokes, the outer diffuse planetary rings at Jupiter, Saturn, Uranus and Neptune, and comets.
