Can we go to Mars without going crazy? In May 2001, Discover’s cover story asked exactly that, exploring unanswered questions about the psychological perils of humans crammed together and flung through space.
At the time, scientists didn’t have much data to predict how people would handle the six-month journey. Researchers realized interpersonal skills and camaraderie would be critical to success.
We’re still not sure how things would go. But growing interest in the mental risks of space travel — which NASA lists as one of the biggest threats to astronauts — has spawned a wave of new research and technology.
Experts are developing stress-management systems, including virtual reality programs and robotic companions, to help interplanetary travelers cope on their trip. And projects that simulate long-term space travel are giving researchers insights into how we’ll deal. Participants endure months in cramped confines in analog missions at NASA’s facilities in Houston, as ...
