When on a mission, Astronauts are expected to conduct experiments to learn more about the planet, moon, or comet. Experiments also allow the astronauts to test theories based on gravity, atmosphere, or mental and physical effects to the body.
Experiments are preplanned by the Astronauts before going on the mission, and time is alloted to each experiment.
Data from experiments during the mission is usually written down and examined after the mission.
