DISTANT SPACE TRAVEL BETTER AS FAMILY AFFAIR
Forget the kind of macho astronauts you are used to seeing in films- space travel to faraway solar systems will probably a family affair conducted by married couples and their kids,' says us anthropologist, John Moore. 'The family has the kind of natural organization to deal with the tensions likely to characterize space trips of 200 years or longer to settle remote planets', says Moore. 'We are less likely to go crazy in space and more likely to accomplish our missions by using crews that are organized along family lines.'
'Whenever colonization is done on earth, it is always by people looking for a better life. All of the colorizations that I know about have been done by families, especially young couples.'
In the past, astronauts had to be specially trained and physically very fit to survive in very small space capsules, but spacecraft size is no longer a constraint, making it possible to take ordinary people such as midwives, electricians and cleaners. For a space crew that is going to colonize a space and reproduce for many generations, these kinds of people will be just as Important as space technologists.
Starting with a population of childless married couples who also works best on board a spaceship because it will give the initial crew a few years to adjust to their surroundings without the distraction and responsibilities of caring for children. People may be horrified at the idea that children will be living and dying space, with their only image of Earth coming from pictures and videos. But, says John Moore, parents have always made choices affecting their children's lives. 'We change jobs, we move to another town, we emigrate to a foreign country. If we educated our space kids properly, I think one day they might say,' Gosh, I'm sure glad I'm on this spaceship and not back on dirty old Earth'.
According to Moore, a starting population of 150 to 180 would best sustain itself at the same rate over six to eight generations. Every person should have the opportunity to be married - with a choice of at least ten possible spouses within three years of their age - and to be a parent.
Ideally, the group should share social and cultural values. 'Having some people accustomed to monogamy and other to plural marriages would create some confusion when it comes time for the sons and daughters of the first generation to marry.' Says Moore. 'Designing morals for people on such a fantastic voyage is problematic because the people on Earth would have little influence once the crew is on its own. If a space crew decides on a system of slavery for some and privilege for others, there is little the planners on Earth will be able to do to prevent it.'
Thinking about this issue is not as far-fetched as you might think. Experts predict that such a space mission will take place the next hundred years.
Why is it better for the first crews of space flights to be childless couples?
A. Childless couples are more responsible than couples with children.
B. Childless couples work harder than couples with children.
C. Crews need to get used to their environment before having children.
D. Couples with children would always put their children first.
