"Me, too!" sneered Roger, his voice filled with a bitterness that
surprised Tom and Astro. "But I didn't think I would find out like this!
How in the universe has that--that tyrant managed to stay alive this
long!"
CHAPTER 5
"The space station's biggest headache," said Terry Scott, a young Solar
Guard officer assigned the job of showing the _Polaris_ crew around, "is
to maintain perfect balance at all times."
"How do you achieve that, sir?" asked Tom.
"We create our own gravity by means of a giant gyroscope in the heart of
the station. When more weight is taken aboard, or weight leaves the
station, we have to adjust the gyro's speed."
They entered the power deck of the great ball-like satellite. Astro's
eyes glowed with pleasure as he glanced approvingly from one massive
machine to another. The fuel tanks were made of thin durable aluminite;
a huge cylinder, covered with heat-resistant paint, was the air
conditioner; power came from a bank of atomic dynamos and generators;
while those massive pumps kept the station's artificial air and water
supply circulating.
Dials, gauges, meters, were arrayed in seemingly endless rows--but each
one of them actually played its part in keeping the station in balance.
