The astronauts were walking on the other side of the moon to collect moon rocks and moon surface samples.
On the way back to the space shuttle they saw a green man run past them.
The astronauts decided to follow the alien and it led them to a U.F.O.
The astronauts were now lost and they decided to knock on the door and ask the aliens for help.
The aliens agreed to help them find the space shuttle if they played a few space games first.
The aliens want you to play parachute games, make an art project, run an obstacle course, play outer space games, and go on a clue hunt.
