to death long ago by unfiltered exposure to the Sun. Suddenly, the two ships explosively decouple, destroying Icarus Is outer airlock and stranding the four crewmembers. With only one spacesuit available, Capa wears it due to being the only crewmember able to operate the payload, while the rest wrap themselves in salvaged insulation material from the walls of the ship and then jettison between airlocks, using the vacuum release for propulsion. Searle realizes that one of them must stay behind to manually operate the airlock and volunteers himself. Searle releases the airlock, shooting Capa, Harvey and Mace out into open space. Harvey misses the airlock, freezes, and dies from asphyxiation, while Capa and Mace make it back to Icarus II. Searle, having spent the mission obsessed with looking into the shielded sun, voluntarily exposes himself to its full, deadly force in the observation room, killing himself in the process. Corazon calculates that there is only enough oxygen left for four of the five survivors to reach the Sun. The group reluctantly decides to have Mace kill Trey, but discovers Trey has already committed suicide. With the remaining crew somewhat relieved that they will now at least make the trip to the Sun, Capa is informed by Icarus that there is still not enough oxygen to complete the mission because an unknown fifth person is on board the ship. Capa investigates and discovers an insane and disfigured Pinbacker, who is revealed to have been behind the decoupling of the airlocks. Pinbacker attacks, wounds, and pursues Capa into the airlock, who seals it from his side. Pinbacker locks his side of the airlock to trap Capa, then kills Corazon and removes the four mainframes from their coolant baths, shutting down the ship's computer, before going after Cassie. Mace manually lowers two of the computers back into the freezing coolant, but when his leg catches on the third descending mainframe, he becomes trapped, and the computer system is disabled. As he freezes to death, he begs Capa to complete the mission. Capa blows the airlock and separates the bomb from the ship, which is burned away by the sun. He then enters the bomb, where he finds Cassie, but they are ambushed by Pinbacker, who claims he spent the last seven years "conversing" with God (the sun) and was told to send all humanity to Heaven. As they hurtle into the Sun, Capa
