If someone said to me I could go right now, I’d have to decline. My wife has zero interest in space exploration, and if we couldn’t go together, then I wouldn’t go. A trip to Mars and back alone would take a year or so, and the whole mission would probably be multiple years in length. That would be too much to ask of my marriage.
However, if you asked five years ago, when I was single and had no marriage prospects, that’d be a tougher call. I get along fine with my family, and love my neices to death. The prospect of not seeing any of them for years might be acceptible, but I’ve never really been confronted with such a choice, so it’s hard to imagine how I’d really handle it.
It would take a unique kind of person, I think, to agree to the one-way trip. Probably many current astronauts could handle five, maybe ten years away, but for good? Humanity hasn’t really faced options like that on a large scale since probably the 17th or 18th century, at the latest. In the technological societies that will be sending these explorers to Mars, we’ve all grown pretty accustomed to being able to get anywhere in at most a few days, and to be able to communicate with our friends and loved ones almost on demand. Hell, we get bent out of shape when we can’t get cell phone coverage. I don’t think any of us can really imagine what it must have been like for explorers and their families in, say, the days of Columbus. Back then, I suppose, people who said goodbye on the dock must have figured odds were about even they’d never see each other again. Voyages took so long, and even our best technology was so fragile, that it was perfectly reasonable to expect the ship might sink, or someone either at home or in the boat would die of some disease or other mishap before they had a chance to reunite. And not knowing! Can any of us handle that anymore? Imagine: Your brother or father sails away West, and at best you may see him six months from now. What if he doesn’t return in six months? Well, maybe storms blew him off course. After eight months? Maybe he’s shipwrecked but still alive. If so, what can you do? There’s a vast ocean, with uncharted islands. How could you ever expect to find a needle in such an immense haystack? What if he drowned, or was killed by pirates or natives? What if he fell ill and succumbed to disease? You would have no clue. You might never know. Eventually you would just have to give up on watching the horizon and waiting, and figure out how to get on with your life in your loved one’s absense. What if it was your husband, and, thinking him long dead, you remarry, only to have him return after ten years’ time?
I guess it will never be that bad for the Martian colonists or their families. At worst, if something goes wrong, they’ll have to wait a day or two before they give up all hope. Maybe that would make it easier. But we’re a much closer society than we ever were in some respects, so the stresses of separation may be more severe.
It’s really a fascinating question to ponder.
