重庆大学将在月球表面种土豆养蚕 人类首次!(图)

另外,科普载荷将搭载马铃薯和拟南芥种子以及蚕卵,到达月球表面后将对其进行栽培和孵化。科普载荷主任设计师张元勋介绍,蚕产生二氧化碳,而马铃薯及拟南芥进行光合作用产生氧气,构建起一个简单的生态系统。
而通过观察低重力、强辐射条件下植物的种子发芽、幼苗生长和开花的全过程,或虫卵孵化、幼虫成长发育、破茧成蝶,验证月球环境下种子的呼吸作用和植物的光合作用,激发人们的生态环保意识。
温控能源方面均为研究难点
科普载荷“月面微型生态圈”工作原理。
但月球表面的气温、重量、湿度等众多环境都与地表不同,如何在38万公里的月球上顺利让植物及昆虫存活,几大难点也让研究团队头疼不已。
张元勋介绍,科学载荷主要的几大难点在于:温控、能源、生态系统的构建和未知的情况。月球表面温度在零下170℃-零上120℃间,而植物及昆虫理想生存温度为1-30℃,所以载荷设置保温层,以保证植物和昆虫的正常生长,同时通过导光管保证光照。
能源问题也是科普载荷需要解决的一大问题,由于载荷重量严格控制在3公斤,所以任何零件的重量都会精确到克,这就必须选用能量密度大的电池,而在温差大、高能粒子冲击的恶劣环境下保证电池正常运转也是一大难题。
谢更新介绍,这是将是人类首次抵达探测器都未接触过的月球背面,各种意料之外的情况都要充分考虑,而他们的目标是将植物和昆虫的生长过程向全世界进行直播,激发民众民族自豪感和爱国热情,提高环境保护意识和探索宇宙的热情。
