Isolation, Hazard of the Mind

Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, our Human Research Program has organized hazards astronauts will encounter on a continual basis into five classifications. (View the first hazard). Let’s dive into the second hazard:

Overcoming the second hazard, isolation and confinement, is essential for a successful mission to Mars. Behavioral issues among groups of people crammed in a small space over a long period of time, no matter how well trained they are, are inevitable. It is a topic of study and discussion currently taking place around the selection and composition of crews.

On Earth, we have the luxury of picking up our cell phones and instantly being connected with nearly everything and everyone around us. 

On a trip to Mars, astronauts will be more isolated and confined than we can imagine. 

Sleep loss, circadian desynchronization (getting out of sync), and work overload compound this issue and may lead to performance decrements or decline, adverse health outcomes, and compromised mission objectives.

To address this hazard, methods for monitoring behavioral health and adapting/refining various tools and technologies for use in the spaceflight environment are being developed to detect and treat early risk factors. Research is also being conducted in workload and performance, light therapy for circadian alignment or internal clock alignment, and team cohesion.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including isolation and confinement.

Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of isolation and confinement with Tom Williams, a NASA Human Factors and Behavior Performance Element Scientist at the Johnson Space Center.
