Two days ago,
The truth was the little alien's best friend, Jeremio, floated to Rhea about 10 days ago. He was sucked by Rhea's gravity on his piece of ice with a rocket the aliens had taken to come to Saturn, and since then his ice had been orbiting around Rhea.
After thinking for a long time, he thought that his best choice was to take off while his ice orbited around Rhea. He turned on the engine, trying to blast off. At that very moment the rocket started to tilt! It tilted forward so badly that all he could see through the rocket's front window was the ice not the stars! SOMETHING is not right!
"Emergency!" he thought. He managed to turn off the engine quickly.
Then he got out of the rocket to see what was going on, and realized he made a BIG mistake. The ice underneath the rocket had melted because of the heat. Now, he decided his only choice was to stay on the ice again.
Time had passed when Jeremio had probably the best idea. He thought to himself, "I had a better chance of surviving on Rhea than on this piece of ice!" So, this idea got into his mind: [It's dangerous but it's worth a try...] He would turn on the engine and make a bigger hole in the ice so the rocket and himself would fall through and land on Rhea… That is a good plan, right? It may be good but at this time there is a better choice…when he suddenly caught sight of a spaceship flying as fast as light from the direction of Saturn.
"Enemy or friend?" he sighed. "If it's a friend, I should put out an SOS signal. If it's an enemy, I should do nothing at all." He pulled out a ball and pretended it was a crystal ball.
"Oh, Crystal Ball, friend or enemy?"
…silence…
"Oh, Crystal Ball, friend or enemy!?"
…silence…
"Oh, Crystal Ball, friend or enemy!?!"
…silence…
"Oh you' re not much help! I will decide myself! I choose friend!" As soon as he said that, he shot a red light 3 times as an SOS.
FLASH FLASH FLASH…
Back to the story,
....
The aliens' spaceship passed by Rhea, and as it approached Titan somebody on the spaceship shouted "Turn back the spaceship! Turn back!"
The alien who said that explained what he saw to his friends as soon as the spaceship changed route. "I saw a flashing red light coming from Rhea," he said. "It' not natural. I think that was someone sending an SOS!"
