Ray Bradbury - Dark They Were, And Golden Eyed
The Bittering family -- Harry, Cora, and their three children Dan, Laura, and David -- has arrived on Mars as part of a new 800-person settlement. Originally from Boston, they have moved to Mars via rocket in order to avoid the anticipated destruction from the war that is being waged on Earth. Cora reminds Harry of just that when he wants to return to Earth immediately after stepping off of the rocket when she says, "One day the atom bomb will fix Earth. Then we'll be safe here." While they were all skeptically optimistic about their new life on Mars, they took comfort in the fact that they could buy a return rocket ticket home at any time.
Soon after their arrival, they are no longer able to rely on this option. Laura runs home one day to tell them that an atom bomb hit New York and all of the space rockets were blown up. The family must accept the fact that they are stranded on Mars forever. Devastated, Harry decides to rededicate himself to his plot of land. As he was working in his garden, he begins to notice that things are the "same, but different," such as the peach blossoms, carrots, radishes, and other produce planted in his garden (4.) Harry begins to panic that Mars is changing him and his belongings, and he runs into town to discuss it with the other settlers.
