No one knows for sure what a long-range space journey will be like for the people on board. Nobody in the history of our species has ever had to deal with the “Earth-out-of-view” phenomenon, for instance. How will it feel to live in close quarters with a small group, with no escape hatch? How will space travelers deal with the prospect of not seeing family or friends for years, or even ever again? How will they occupy themselves for years with nothing much to do?
Researchers do know some things from observing astronauts who’ve stayed in space stations revolving around Earth for long periods of time, people who spent a lot of time shut off from the outside world in isolated regions (such as on polar expeditions) and from experiments with simulated Mars missions.
Because astronauts would have a lot of free time to fill, some researchers have casually suggested sending along a selection of books and films or even bespoke video games. As a social scientist who studies media use and its effects on behavior, I believe television could help. Recreating the media environment from before we had permanent, continuous access to anything we want to watch or listen to might be just the thing to help space travelers cope with a loss of a sense of space and time, with loneliness, privacy issues, boredom and more.
