But we can learn to land on these asteroids that have our name on them and put something like a small ion propulsion motor on it, which would gently, slowly, after a period of time, push it into a different trajectory, which, if we've done our math right, would keep it from hitting Earth.
但我们能够着陆在这些由我们命名的行星上， 并予之一个离子推进器， 能够缓慢的在一段时间内将行星改道， 如果我们计算无误，就能够阻止它撞向地球。
