载人航天器在飞行过程中,会产生大量的废物,尤其在长期飞行或星际飞行中,产生的废物更多。以火星探险为例,如果是一个6人组成的探险小组,飞往火星和返回的时间是2年,将会产生超过6吨的固体有机废料,其中绝大部分是粪便。如何处理它们呢?过去是将这些废物带回地面或将其抛弃在太空。这种作法使有限的飞行舱内必须腾出很大的空间来装废物,造成飞行空间的狭窄。能不能变废为宝,利用太空中的废物,生产出为太空人服务的产品呢?在一次漫 Manned spacecraft generates large amounts of waste during the flight, generating more waste, especially in long-haul flights or interstellar flights. Take Mars Exploration for example. If it is a 6-person exploration team, flying to Mars and returning for 2 years will produce more than 6 tons of solid organic waste, most of which is manure. How to deal with them? In the past is to bring the waste back to the ground or abandoned in space. This practice has made it necessary to make room for a limited space in the flight capsule to contain the waste, resulting in a narrow space for flight. Can waste turn treasure, the use of space debris, to produce products for astronauts? In a diffuse
