After six months of mission time, a solar storm hits the ship, knocking out communication with mission control. Blok and Corrigan perform an extra-vehicular activity (EVA) to repair the system from outside but an accident rips Blok’s suit. While he is being guided back into the airlock, Blok notices that Corrigan’s suit has been coated with hydrazine and he cannot enter the airlock or else he would contaminate the rest of the ship. Blok attempts to save Corrigan by taking him out of his suit, but he blacks out from a lack of oxygen. Knowing there is no hope for himself, Corrigan pushes Blok into the airlock, thus propelling himself away from the ship as it continues its journey to Europa. Stranded, he dies in space; the crew continue with the mission, demoralized by Corrigan’s death.
