Speed is everything on the way to Mars, and not only because a seven-month trip in a confined space can be torturous. The bigger problem is that it can also be lethal because of radiation exposure in deep space, where the absence of Earth's magnetic field leaves astronauts far more exposed to deadly cosmic energy than they are in orbit or on the way to the moon.

在火星上，速度就是一切，不仅仅是因为七个月的空间受限制旅行是一种折磨。更大的问题是，它也可以是致命的，因为暴露在外层空间的辐射中，并且不受地球磁场影响，使得宇航员承受比在轨道上或去月球的路上更多致命的辐射。
