The Situation of A Manned Mission to Mars
Posted by The Situationist Staff on June 5, 2008
With the Phoenix Lander roaming around Mars for the last two weeks, some have wondered about the prospects of a manned mission to the Red Planet. Although such a mission probably won’t happen for a long time — last September, NASA administrator Michael Griffin predicted that a manned mission to Mars won’t occur until at least 2037 — the subject of extended space travel of humans is one poised to become more realistic in the decades and centuries ahead.
Below we excerpt a story from Lara Farrar on CNN.com that considers the intense psychological stress, loneliness, and humbleness likely to be experienced by astronauts who make such journeys.

If Dr. Robert Zubrin could take a trip to Mars, he would be sure to pack a bread maker in his suitcase. Not just because bread is a pretty reliable expeditionary food, but because the act of cooking, according to Zubrin, seems to help people get along with each other, especially when they are in slightly dire, less than luxurious and more than stressful circumstances.
And Zubrin would know, too. He has, after all, led almost a half-dozen mock Mars missions on barren Arctic ice fields and scorching Utah deserts with volunteer teams made up of students, scientists, journalists and anyone else willing to wear fake spacesuits and live in tiny tin-can-like habitation modules for days on end.
The simulated expeditions were made, in part, to research ways to live and work on the Red Planet. But they also revealed something else: what personality types might best be suited to make the 35 million-mile journey and who would be better off watching from Mission Control.
“Some of these crews have worked out very well,” said Zubrin, president of the Mars Society, a 7,000-member multinational group determined to reach what it calls the New World. “Others were at each other’s throats.”

While it will probably take at least another 20 years before Zubrin — or anyone else for that matter — makes it to the Martian surface, NASA and other space agencies are already drawing up plans for a voyage that will present astronauts not only with physical but also psychological challenges never faced by humans before.
“When you go to Mars, all bets are off,” said Dr. Nick Kanas, a professor at the University of California, San Francisco, who has studied astronaut psychology. “We don’t know what is going to happen.”
One particularly important task, Kanas explained, will be picking a team of astronauts who can both work and get along with each other on a trip lasting at least two years, spent mostly within the confines of a not-so-big spacecraft sailing through the dark. The European Space Agency and the Russian Institute of Biomedial Problems are scheduled to run a joint 520-day mock Mars expedition this year aimed to study the effects of extreme isolation and confinement on 12 volunteers.
The numbers of men and women, their ages and even cultural upbringings must be carefully calculated to try to prevent what could be potentially devastating cosmic quarrels. “You can’t just take a walk and get away from somebody,” Kanas said.

[T]hey will not be able to receive surprise presents, like special cookies or favorite movies, which are often brought to the space station on supply shuttles when someone starts feeling homesick or maybe a little blue. Thus, decking out the Martian-bound craft with family photographs, special trinkets, books and even plants will be crucial for a mostly monotonous extraterrestrial road trip that will bring a whole new meaning to the “are we there yet?” question.
“If someone gets suicidal, you have to take care of it on board,” Kanas said. Mission Control might also have to make some tough calls, like whether to tell an astronaut about a death in his or her family or other tragedies back home.
Yet the big unknown, according to Kanas, does not involve who astronauts will not be able to talk to or what gifts they will not be able to get, but instead what they will not be able to clearly see: planet Earth.
Kanas has even coined a term for the situation: the “Earth out of view” phenomenon.
“Nobody in the history of mankind has ever experienced the Earth as a pale, insignificant blue dot in the sky,” he said. “What that might do to a crew member, nobody knows.”
