“月宫宇航员”推迟5天“回地球”

  “月宫宇航员”推迟5天“回地球”

记者在昨天北京航空航天大学举行的“月宫一号”科普基地开放活动上获悉,原定于今年5月10日结束的“月宫365实验”将延期5天,以考察志愿者在全密闭的舱内心理情绪变化情况。在此前进行的300多天实验中,“月宫一号”实验舱系统已经可以稳定地为不同代谢水平的乘员提供生命保障。该实验将为我国今后探索月球、火星及外太空的生命保障打下坚实基础。

“月宫一号”是世界首个也是密闭程度最高的四生物链环生物再生生命保障系统。它与外界密闭隔绝,内部营造出一个特殊的“生物圈”。在舱内开展科研的志愿者自己种植粮食、蔬菜,连氧气、水也是自主循环使用零排放,几乎完全模拟了未来人类探索外太空所要面临的生活、心理挑战。

“月宫365实验”从2017年5月10日开始,8名志愿者交替分三个班次进入舱内封闭生活365天。据了解,志愿者们在“月宫一号”里种植了小麦、生菜、茼蒿、西红柿等30多种农作物和蔬菜。实验原本预计2018年5月10日结束。不过昨天该实验首席科学家刘红透露,实验将临时新增“应急加班”实验,为期5天,由此总时长达370天,即志愿者5月15日才能正式出舱,以考察志愿者心理情绪变化情况。“上周才告诉他们,就是想看每个人不同的反应。”刘红说,近期他们正利用量表、心率和血压、脑电波测量仪器等来测试志愿者反应,积累相应的数据。

刘红告诉记者,此前300多天的实验基本可以证明,这个系统可以稳定地为不同代谢水平的乘员提供生命保障,且系统可靠性非常高。据了解,未来“月宫一号”团队将积极争取我国月球、火星探测器的搭载机会和资源,在月面、火星表面开展小型生物再生生命保障系统试验,通过与地面平行试验的对比分析,获得地面大型系统模拟结果的矫正参数,为未来应用于人类探测月球、火星奠定基础。(记者 张航)
