After several previous failed attempts, the crew is tasked with a mission to observe, research, and analyze long-period comets that have entered our solar system. Astronauts in both Mission Control and Spacecraft conduct experiments to study comets to help scientists better understand how they are formed and how they could potentially impact Earth. During the mission, however, a shocking discovery is made, and the crew must brainstorm together to solve the emergency, ensuring the safety of the crew and the success of the mission.
