Given the question: Generate a question that has the following answer: Mars and Venus for the following movie plot: Mala (Evan Rachel Wood) and her friend Senn (Justin Long) are young alien creatures who live on Terra, a planet from a star system in the Milky Way. Terra is a peaceful planet of alien creatures who have a rich semi-advanced culture. One day a large, mysterious object blocks the Terrian sun, piquing the Terrians' interest. However, since the Terrian culture bans the development of new technologies, such as telescopes, without the approval of the ruling council, none of the inhabitants are able to get a closer look at the huge object in their sky. Mala, who is inventive and headstrong, goes against the rules of her community and creates a telescope, which she takes out into the dark empty area outside the Terrian city and uses to view the object and witnesses smaller objects coming from the large object that turn out to be incoming scout spaceships. She returns to the city to find that the scout spaceships have already started abducting Terrians (who willingly offer themselves to the scout spaceships mistaking them as their new "gods"). After Mala's own father, Roven (Dennis Quaid) is abducted she goads a ship into tailing her and lures it into a trap, which causes it to crash. Afterward, she saves the life of the pilot, revealed to be a human, an officer named Lieutenant Jim Stanton (Luke Wilson). After his personal robot assistant named Giddy (David Cross) warns Mala that Stanton will die without a supply of oxygen (which the Terrian atmosphere does not contain), she creates an oxygen generator and fills a tent with air containing oxygen so that Jim can breathe, and eventually convinces Giddy to teach her human language. The Robot informs Mala that the mysterious object is a generation ship called The Ark, containing humans from Earth. Centuries beforehand, both Mars and Venus were terraformed by humans and colonized. But 200 years later, the two planets demanded independence from Earth, which the Earth government refused to grant them due to the high demand of resources from the two colonies. The dispute...
