Original passage 4
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 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.
Paraphrase:
It is essential to focus on the
speed to travel to Mars not only because a long journey inside a small narrowed
spaceship. The primary issue is that it can be fatal due to the radiation contact
in the dark space, and because there is no magnetic area from the Earth which
leave the spacemen saturate with this lethal cosmic, similar to the way to the
moon. (Kluger, 2004, P.42-50)
