Living on Mars would be extremely difficult and very few people understand that better than Carmel Johnston.
The environmental scientist for NASA spent a year living inside a cramped dome with five other scientists in a year-long mission to mimic living on Mars.
Given the incredibly harsh and inhospitable conditions on Mars, any human expedition to the planet would involve living in a small self-contained environment, protected from the elements. But before that ever happens, NASA researchers wanted to study the psychological effects such a lifestyle would have on the astronauts who volunteered to be plonked on Mars for an extended stay.
“Everything from day-to-day life in isolation, they were wanting to learn about,” Johnston said.
The 27-year-old was the Commander of the latest Hawaii Space Exploration Analog and Simulation Mission (HI-SEAS) and her job was to communicate with mission support about what the crew needed to do each day.
Their habitat was perched between two of the world’s largest volcanoes in Hawaii at almost 8,200 feet above sea level. Each scientist had a bedroom about the size of an “under-the-stairs cupboard” and along with just 850 square feet of usable space — including a kitchen, dining room, two bathrooms, lab, exercise area and common areas.
As you could imagine, living in such close quarters led to some testy moments between the scientists.
“As every family knows you don’t always get along all the time. We had plenty of arguments during the year,” she said. “Working through that just to figure out how to get along just to get to the next stage was really important.”
One of the drawbacks of being chosen to lead humanity’s push to become an interplanetary species is having to give up your privacy.
“You could hear everything else that happened in the dome, and they could hear you,” Johnston recounted. “It wasn’t very private at all.”
Living on top of each other made for some intimate, and rather icky, situations.
‘So we had to clean the toilets every week … we had to remove compost from there. It became a stinky issue …’
“It seems like every simulation or mission has issues with their toilet,” she said. “It’s always one of the big issues. So we had to clean the toilets every week … we had to remove compost from there. It became a stinky issue rather than an unclean one.”
About two or three times a week the team would leave the dome for the outside world, but of course, that involved donning a heavy space suit to contend with the Martian conditions.
The make-believe astronauts would receive a food drop about every four months with freeze dried, dehydrated and powdered ingredients from which they made their food.
“Ideally if you were on a trip to Mars you would have all sorts of life support systems and plant growth systems that could produce all of your food but (this) experiment was … more geared towards the social and psychological aspects,” she said.
The only contact they had with the outside world — and their loved ones — was via e-mail with a 20-minute delay each way to replicate the time it would take to get a message to Mars.
The one thing that she missed which really surprised her was avocados, for which she had a daily craving.
However, it might please you to know that the toughest thing for Johnston and other crew members was something we all experience as Earth-dwelling beings: getting stuff done. The days in isolation were strange to get accustomed to and the participants had to adjust to their new lifestyle and feel like they were achieving what they wanted to.
“If you have a bunch of over-achievers in one area, it’s very easy for them to feel that they’re not getting enough done,” she said.
The six scientists filled out more than 3,000 surveys throughout the year, but NASA has not yet released the findings from its intensive study.
