Use of Free Time During Long-Duration Space Missions

During future long-duration space missions, crewmembers will be subjected to periods of free time which may be monotonous and hypostimulating. Ground-based studies and Russian space missions have shown that dysphoria and interpersonal tension can occur during these times, and our survey of 54 astronauts and cosmonauts suggests that long-duration space travelers value access to media that can be used to occupy free time. Activities should be individualized, capable of privacy, and flexible enough to account for changing preferences. Important media include audio and video cassettes, news teleprinters, books, two-way televisions, games, and hobby and professional supplies.
