Commander Col. Van Heusen is unconvinced and makes sure that Carruthers is constantly accompanied by another member of his crew. While the ship was on the Martian surface, a large external exhaust had been left open, allowing the creature easy access. The crew are at first skeptical that something crawled aboard while they were on the Mars. However, when Kienholz investigates odd sounds coming from a lower level, he is killed and his body hidden in an air duct. Next is Gino Finelli. He is found, barely alive, but the creature attacks his wouldbe rescuer. Bullets have no effect, forcing the crewman to leave Gino behind, much to the distress of his brother Bob. An autopsy of Kienholzs body reveals it has been sucked dry of all fluids.The crew use hand grenades and gas grenades, but the creature proves immune to both. They next try electrocution, with no effect. When It goes into one of the spaceships atomic reactor rooms, they shut the heavily shielded door and expose the creature directly to the ships nuclear pile. It easily crashes through and escapes. The creature is so strong that It can tear through the metal hatches separating each level of ship. The survivors except for one crewman, who is trapped below in a spot inaccessible to the creature retreat to the control room on the topmost deck. When Carruthers notices the ships higherthannormal oxygen consumption rate, he surmises that this is due to the creatures larger lung capacity, needed for the thin Martian atmosphere. In a last desperate move, everyone puts on their spacesuits, and Carruthers opens the command decks hull airlock directly to the vacuum of space. A violent decompression follows, and the plan works It suffocates and finally expires, stuck part way through the final hatch. ........
