Space's Ocean

"So you're going to Saturn!" shouted the rocket officer through the sound of the roaring rocket engine.
"Yes!" Jack the rocket pilot shouted back.
"Taking off in five, four, three, two, one, BLAST OFF!" shouted Jack's assistant Daniel.

"We are one million Kilometres from Saturn," exclaimed Daniel to Jack.
"Good, any asteroids on track A?" asked Jack.
"No, but heaps on track C," replied Daniel.

"Now come on, we have to explore Saturn's ring," said Jack as the engine of the rocket calmed down.

Half an hour later they were looking at an ocean, in space separating the ring from the planet.
"Wow!" yelled Daniel excitedly.
"We have to tell the others up - I mean down on Earth," said Jack.
