chunk: The commercial spacecraft Nostromo is on a return trip to Earth with a seven-member crew in stasis: Captain Dallas, Executive Officer Kane, Navigator Lambert, Science Officer Ash, Warrant Officer Ripley, and Engineers Parker and Brett. Detecting a mysterious transmission, possibly a distress signal, from a nearby planetoid, the ship's computer, MUTHR, awakens the crew. Following standard company policy for such situations, the Nostromo lands on the planetoid and Dallas, Kane, and Lambert head out to investigate, damaging their ship upon landing in dust. They discover the signal is coming from a derelict alien spacecraft. Inside, they find the remains of a large alien creature whose ribcage appears to have exploded from the inside.
