Lesson 35-2 Space odyssey

Because the gravity on the Moon's surface is only a sixth of Earth's (remember how easily the Apollo astronauts bounded along), it takes much less energy to accelerate to that 1.5 miles per second than it does on Earth. Moon-dwellers will be able to fly in space at only three per cent of the cost of similar journeys by their terrestrial cousins.

Arthur C. Clark once suggested a revolutionary idea passes through three phases:

1 'It's impossible -- don't waste my time.'

2 'It's possible, but not worth doing.'

3 'I said it was a good idea all along.'
