Onboard autonomous navigation, or a self-driving spacecraft, if you will, is one of the top technologies needed if we are going to survive in deep space.

机载自主导航， 或自动驾驶航天器， 如果你愿意的话，是我们要在深空生存所需的顶级技术之一。

Onboard autonomous navigation means we can support more spacecraft, more sensors to explore the universe, and it also frees up navigators -- people like me -- to work on finding the answers to other questions.

机载自主导航意味着我们可以支持更多的航天器、更多的传感器来探索宇宙，它也解放了导航员——像我这样的人——去寻找其他问题的答案。
