In 2137, 15 years after the Nostromo set down on LV-426, the Anesidora found the Nostromo's flight recorder, detected the same beacon, and subsequently landed on the moon to investigate and salvage anything of value. The crew discovered the derelict ship and equipment left behind by the Nostromo personnel. While exploring the derelict, Henry Marlow, the captain of the Anesidora, used a tracking device to locate the beacon and disable it, preventing any other salvage vessels from discovering the ship.
