12月30日凌晨,“神舟”四号无人飞船顺利发射升空,华夏儿女畅游太空的日子已不再遥远,我们的航天员也正摩拳擦掌。更让人感兴趣的是,航天员上了天,在太空如何吃穿住行?为此,我们采访了中国载人航天工程航天员系统航天食品、航天服和环境控制与生命保障分系统的有关专家。吃:营养最重要为了节省飞船的空间和发射时的有效载荷,航天员携带的航天食品尽可能重量轻、体积小、营养好,而且不含残渣,如骨、刺、皮、核等。此外,航天飞行会导致航天员骨钙丢失、肌肉萎缩、红细胞数量减少,因而航天食品必须符合失重条件下航天员生理改变的要求。我国的航天食品有中国特色。太空生活中,我们的航天员可以吃到中式菜品,如鱼香肉丝、宫爆鸡丁等,比西餐更加色香美味。航天员饭后还需用
On the early morning of December 30, the unmanned spacecraft Shenzhou IV was launched successfully. The days for Chinese children to swim in space are no longer far away. Our astronauts are also gearing up. Even more intriguing is that astronauts went to space and how to eat, wear and walk in space? To this end, we interviewed China’s space project astronaut space system for spaceflight, spacesuit and environment control and life support subsystems Relevant experts Eat: the most important nutrition In order to save the spacecraft spacecraft and launching the payload, astronauts carrying space food as light weight, small size, good nutrition, and free of debris, such as bone, thorns, skin, nuclear and so on. In addition, the space flight will lead to astronaut bone calcium loss, muscle atrophy, reduced red blood cell count, so aerospace food must meet the requirements of astronauts physiological changes under conditions of weightlessness. China’s space food has Chinese characteristics. In space life, our astronauts can eat Chinese dishes, such as fish-flavored pork, gingko chicken, etc., which are more delicious and savory than western food. Astronauts need to use after meals
