As a serious concept, interstellar travel has been debated fiercely by various scientists, science fiction authors, hobbyists and eccentrics, but has seldom been taken seriously in the academic community or the mainstream public. Many ideas for managing this feat have been thrown around, ranging from Star Trek's Warp Drive and hyperspace? engines of various sorts, to trips which involve very long waits and either multi-generation crews or [cryogenic freezing]?. As current technology stands, we have no good solution; unless a dodge involving theoretical higher dimensions is found, any travel to other stars is doomed to be slow and dull. |

At the end of the 20th century, we have sent 12 people to land on the moon and return safely. We have sent robot spacecraft to fly past most of the major planets of our solar system, and land on two of them. |

We have sent robot spacecraft to fly past most of the major planets of our solar system, and land on two of them. Four of these spacecraft (Pioneer 10 & 11, Voyager 1 & 2) are on course to leave the Solar System, but will cease to function long before reaching the Oort Cloud. |
