Scientists already trying to stop Mars astronauts from killing each other

Mission to mars

NASA hopes to send a group of astronauts to visit the Red Planet sometime in the 2030s, and while the most high-profile part of the preparation for that mission is making sure we have the right spacecraft to safely carry astronauts to and from Mars, scientists are also worrying about the mental health of the space explorers who would attempt such a mission.

Unlike a trip to and from the moon, which only took Apollo astronauts a few days, a voyage to and from Mars could last up to three years. That’s three years spent mostly in a capsule that would make the smallest of studio apartments seem roomy, with no opportunity at all to escape from your fellow astronauts and their annoying habits. Plus, after a while, you wouldn’t even be able to see Earth anymore, and once you arrived at Mars, you’d have to contend with a 20-minute communications delay with Earth, which means that even in the most dire of emergencies, you’d have to wait by the phone for a while to see if NASA heard your cries for help.

It’s not hard to imagine that even the sturdiest of astronauts attempting such a journey could just freak right the hell out one day and push a colleague out of an airlock. That’s why NASA is working to develop technology to prevent such psychological traumas before they happen.

The agency recently awarded a $1.3 million contract to a group of Michigan State University psychologists who are working to develop a kind of sensor “badge” that all astronauts on the Mars mission would wear. In theory, the sensor would monitor various indicators of psychological health, including heart rate and blood pressure, while also keeping track of how social interactions with other astronauts play out, in an effort to see signs of a confrontration before it actually happens.

In theory, the badge would monitor things like length of conversation, tone of voice and vital signs all at once, thereby assessing whether an astronaut is being overly aggressive or confrontational. From there, the badge would provide some kind of feedback, like suggesting the astronauts “make up” or warn an aggressive person to tone it down.

There haven’t been many reported severe psychological incidents with astronauts over the years, but that’s in part because astronauts are often afraid to admit that they can’t handle the unique pressure of the job. That unwillingness to admit you’re struggling is a particular concern when NASA is trying to send astronauts out into the darkness of space for three years.

To combat this element of the psychological strain of a Mars mission, NASA is also working with Harvard scientists to develop computerized “therapists” that astronauts could consult during the Mars journey. The agency is also already conducting simulations of long-term missions, and working with psychologists to determine how to assemble the most psychologically compatible group of astronauts for the Mars mission.

What do you think? Can humans really handle this trip?
