415 Red Moon, Dark Moon, Light Moon

 "The three moons, according to their orbit and distance from the planet as well as their own geological quality, have different appearances if seen from the planet itself. One of them is bloody red, another one is inky black, and the last one is shining bright.

"According to the ship-wide vote last week, they are respectively named Red Moon, Dark Moon, and Light Moon. And now we're landing on the moon closest to the planet, the Light Moon."

The Hope had been idling above the Light Moon for more than a week now. It was not that the Hope wanted to stop there, but for the sake of absolute safety, they had to carry out plenty of calculations, exploration, and detection before they could allow the Hope to land on it.
