NOBODY KNOCKED

摘要

What would I do if I could take family or friends up to the space station for just an afternoon? I would show them our planet. You can look out of the window at its stunning views endlessly. On the dark side of the orbit, I'd show them the universe in its fascinating infinity. Seeing this contrast, any person begins to feel that humanity is doomed to be alone for the next hundreds or even thousands of years. Nobody knocked on our windows while we were up there. At the same time, you get a sense of concern to preserve all that evolution has created. It is very likely that life on Earth is unique. Our task is to preserve the planet for future generations and, if possible, to spread life in the universe.
