Lesson 35-2 Space odyssey
Because thegravity on the Moon's surface is only a sixth of Earth's (remember how easilythe Apollo astronauts bounded along), it takes much less energy to accelerateto that 1.5 miles per second than it does on Earth. Moon-dwellers will be ableto fly in space at only three percent of the cost of similar journeys by theirterrestrial cousins.
Arthur C. Clarkonce 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 agood idea all along.'
