Lesson 35-3 Space odyssey
The idea of colonising Mars -- a world 160 times more distant than the Moon --
will move decisively from the second phase to the third, when a significant number of
people are living permanently in space. Mars has an extraordinary fascination for
would-be voyagers. America, Russia and Europe are filled with enthusiasts -- many of
them serious and senior scientists -- who dream of sending people to it. Their aim is
understandable. It is the one world in the Solar System that is most like the Earth. It is
a world of red sandy deserts (hence its name -- the Red Planet), cloudless skies, savage
sandstorms, chasms wider than the Grand Canyon and at least one mountain more than
twice as tall as Everest. It seems ideal for settlement.
