途径一:从地球装载而来太空中是没有水的,宇航员获得饮用水的途径之一就是从地球装载。我国已发射的“神舟五号”到“神舟十号”飞船中,有五次实现了载人飞行(“神舟八号”搭载模拟人),所需要的饮用水同食品一道是从地面装载升空的。为了确保水源没有任何污染,航天员的饮用水取自地下1700米,同时使水中的杂质含量降至最低。经过净化处理后,航天员饮用水的纯度可以达到99.99999%,堪称目前“最纯净的 Path 1: loading from Earth is a space without water. One of the ways for astronauts to get drinking water is to load them from the earth. China has launched ”Shenzhou 5“ to ”Shenzhou 10“ spacecraft, five were achieved in manned flights (”Shenzhou VIII“ equipped with simulators), the required drinking water with food One is loaded from the ground up. To ensure that there is no water pollution, astronauts drink 1700 meters of underground drinking water while minimizing the amount of impurities in the water. After purification, astronauts purity of drinking water can reach 99.99999%, called the current ”purest
