And all of these robotic missions are part of a bigger human journey: a voyage to understand something, to get a sense of our cosmic place, to understand something of our origins, and how Earth, our planet, and we, living on it, came to be.
所有这些机器人探测计划都是人类征程的一部分： 一个为理解而出发的征程，为理解我们置身的宇宙， 为理解人类的起源，为理解地球、 和人类的发展。
