The derelict on LV-426, codenamed Origin and also known as the alien derelict, was a crashed Juggernaut-type Engineer spacecraft. Some time in 2122, a warning signal being broadcast from the derelict was detected by the Weyland-Yutani Corporation and the commercial hauler USCSS Nostromo was subsequently sent to investigate, without the knowledge of its crew. The ship was believed to have crashed on LV-426 several millennia prior to the arrival of the Nostromo.
