Annyira nem ismerem, meg meg kell még néznem, de így wiki alapján ez az:

Meanwhile, Peter Hathaway is living retired on Mars with his wife Alice and daughter Margarite, even though everyone else has departed. Hathaway is a mechanical tinkerer, who has wired an abandoned town below their house to sound alive at night with noise and phone calls. One night, he sees a rocket in orbit, and puts on a laser light show to signal the rocket. It turns out to be Father Stone and Wilder, who have just returned from Earth. They land and have a reunion with Hathaway, who is troubled by his heart. Undeterred, Hathaway brings the crew to his house for breakfast. Wilder remarks that Hathaway's wife looks exactly as she did many years ago when they got married, as he knows her real age and was present at their wedding. Wilder goes off to check some headstones that he saw earlier. He returns, pale, and says that the adults now before them died in July 2000.
The Hathaways give Wilder and Father Stone a toast, but Peter Hathaway's heart fails and he dies, begging Wilder not to call his family because they "would not understand." Wilder then confirms that Alice and Margarite were made by Peter Hathaway. The android family continues on with its meaningless daily life, alone. Ben Driscoll lands shortly after the rocket has departed. The Hathaways are relieved when Driscoll asks if he can stay with them.
