Some 2009 science fiction about the moon might have explored the idea of terraforming it. This means changing the moon's environment to be more like Earth's, perhaps by creating an atmosphere and liquid water. It was a popular concept as it opened up the possibility of the moon becoming a true second home for humanity.
In 2009, moon - related science fiction could have focused on the moon's hidden secrets. Maybe there were stories about ancient civilizations or long - lost technology hidden beneath the moon's surface. This would attract the attention of both scientists and adventurers in the fictional universes.
