Will space tourism become common in the near future?宇宙旅行は近い将来、一般的になるだろうか？

模範解答

Space tourism is no longer just a dream, but I do not think it will become common in the near future. My first reason is the cost. Even a short trip to the edge of space currently costs hundreds of thousands of dollars, which is far more than most people earn in several years. Although reusable rockets are making launches cheaper, it will probably take decades before prices fall to the level of an overseas holiday. My second reason is safety and health. Space travel puts strong forces on the body, and passengers need medical checks and training before they fly. Accidents in spaceflight are rare but serious, and many people would hesitate to take that risk. For these reasons, space tourism is likely to remain a special experience for a small number of wealthy people for many years to come.

宇宙旅行はもはや単なる夢ではないが、近い将来に一般的になるとは思わない。第一の理由は費用である。宇宙の入り口までの短い旅でさえ、現在は数十万ドルかかり、これはほとんどの人が数年かけて稼ぐ金額をはるかに上回る。再利用型ロケットのおかげで打ち上げは安くなりつつあるものの、料金が海外旅行並みに下がるまでにはおそらく何十年もかかるだろう。第二の理由は安全と健康である。宇宙旅行では体に強い力がかかるため、乗客は飛行前に健康診断や訓練を受ける必要がある。宇宙飛行の事故はまれだが深刻であり、多くの人はそのリスクを負うのをためらうだろう。以上の理由から、宇宙旅行は今後何年も、ごく一部の裕福な人々のための特別な体験であり続ける可能性が高い。
