The ion rocket is another means of providing thrust, more gradually but also more efficiently than a conventional rocket. ... As in the nuclear rocket, the energy which propels the xenon jet comes from a different source; here it is electrical energy from solar cells. The reason an ion rocket is much more efficient than ordinary rockets is the way its jet is produced. ... As with solar sails, solar ion engines are mainly practical in the inner solar system, where ample sunlight is available. ...
