1. What kind of challenges to the human body come from traveling or living in space

Because in space there’s no gravity, so when we are in space if we don’t exercise everyday our mossle will shrink.

因為太空是無重力狀態，所以在太空中如果我們不刻意去運動的話我們的肌肉必定會萎縮。

2. What kinds of special nutrients might be missing or needed when traveling in space

In today's society, traveling basically it’s not very much needed and cannot be brought into space.

在現在的太空旅行中好像基本上都還好，因為他們想要甚麼只要有冷凍乾燥基本都可以帶上太空。

3. Special requirements or constraints of space food

It must be cool, dry, easy to carry and easy to clean.

必須是冷凍乾燥並且容易攜帶以及容易清理。
