Summary: Staying sane in outer space: Virtual-reality therapy for astronauts.
The dangers of long-duration space missions aren't just physical. Limited social outlets, loss of privacy and distance from family--and from Earth--can leave astronauts vulnerable to depression and interpersonal conflicts. A recent NASA report warns that psychosocial interaction in outer space "may well be one of the more serious challenges to exploratory missions by humans."
To combat this, NASA is developing a self-help system to address conflicts and assess psychological disorders such as mild depression. The program could be modified for use in other extreme environments such as submarines or oil rigs.
Dubbed the Smart Medical System for Psychosocial Support, the program will combine video, audio, text and graphics to create a lifelike environment. Actors are cast as virtual crew members in prerecorded scenarios that astronauts then use when problems arise. In a typical simulation, an astronaut witnesses a conflict between two virtual crewmates and must decide whether to remain neutral, attempt to mediate or take sides. Each scenario has various choices, based partially on input from veterans of long-duration space flights.
"We started by addressing the conditions most likely to occur," says lead researcher James Carter, Ph.D., of Dartmouth Medical School. "We hope to expand the program to prevent other disorders, such as anxiety." A prototype of the system is expected to be completed and evaluated by October 2003.
Eventually, astronauts will need tools to cope with other psychiatric disorders. Carter points out that the current plan for a human mission to Mars entails nine months of travel time in each direction in addition to one year on the planet itself.
