Space travel isn’t all glamor: Body odor and bad breath hang around; food and filth float; emotional pressure builds; weightlessness degrades bone and muscles; the body experiences higher radiation levels; and risks of kidney stones and eye problems mount.
Clearly, astronauts require a pioneering spirit, but near-future space colonists will need more than guts and gusto to thrive en route to, and on, other worlds. What constitutes an ideal astronaut candidate? Should we select space travelers based on genetic risk factors? Could we train colonists from childhood to be better adapted, mentally and physically, to life in space? And would we be willing to go to the extreme of changing what it means to be human?
“You know, you can see it for miles – goes on for miles, over the hills and everything. But, so does the M6. Do you know what I mean? You can see that for miles. And you go, ‘Great. And that does a job. You can drive on that.’” Thus did an unimpressed Karl Pilkington of An Idiot Abroad describe the Great Wall of China, allegedly the only manmade object visible from space.
Which raises and interesting question: Why can’t you see the British M6 motorway from space? Or can you? For that matter, can you actually see the Great Wall?
While Russian launches fail by the dozen, threatening operations aboard the International Space Station, and the American space program stalls amid political wrangling, China is building its own space laboratory, growing its satellite network, expanding its crewed space program, upgrading its launch facilities, improving its lift vehicles and laying the foundations for a moon shot. Are we witnessing the dawn of Chinese dominance in space?
