B. A Study Reveals Some Emotional Effects of Space Travel

Narrator: This is Science Today. American astronauts and mission control personnel, who participated in Mir Space Station Missions, were found to be less happy with their working conditions than their Russian counterparts. Nick Kanas, a psychiatry professor at the University of California, San Francisco, conducted this NASA-funded, four and a half-year psychological and emotional study .

Kanas:Because of the plans for the International Space Station and since the shuttle MIR missions were seen as phase one of these plans, NASA became interested in looking at how the crewmembers interacted and performed in space.

Narrator: One reason American astronauts were not as happy as the Russians, Kanas says, is they were almost always outnumbered and never in command. They then displaced their negative feelings to mission control personnel.

Kanas: The displacement phenomenon is one that needs to be taken seriously. The evidence suggests that if it does occur - not a surprise because it occurs on Earth in all of our work environments.

Narrator: Based on his findings, Kanas will be making recommendations to NASA to improve the psychosocial environment for future, international missions. For Science Today, I'm Larissa Branin.
