太空是个充满魅力的神奇世界,在太空的生活更是个充满魅力、令人好奇的神奇话题。 太空环境与地球环境大不相同,那里没有空气,没有重力,充满危险的太空辐射。当然在封闭的空间站或航天飞机舱内,有足够的空气供你呼吸,良好的航天器屏蔽材料可以有效地挡住太空辐射,只是“失重”会给生活带来一些麻烦。 如果用地球上的方式去太空生活,那肯定会闹出很多大笑话。比如吃饭,你端着一碗米饭,那饭会一粒粒飘满你的座舱,你张着嘴可能一粒也吃不着;而你闭上嘴时,饭粒却可能飘进你的鼻孔呛你个半死。你想躺在床上睡个舒服觉,可是你会发现太空中找不到上下的界限,“躺”和“站”几乎没有什么区别…… 那么宇航员们是如何在太空中吃饭与睡眠的呢? 100多种太空食品 宇航员的食物丰富多彩,从最初的十几种已经发展到了100多种。宇航员每天一般吃4顿饭,一周之内的食谱不重复。有人以为宇航员的食品都是做成牙膏状的挤着吃,肯定很乏味,其实这是早期宇航员的状况,现在早已今非昔比了。宇航员可以在太空中吃到香肠馅饼、辣味烤鱼、土豆烧牛肉、奶油面包、豆豉肉汤、金枪鱼沙拉、饼干、巧克力、酸奶、果脯、果汁等各种各样的佳肴,美国宇航员甚至可以喝到他们爱喝的可口可乐。不过,宇航员吃饭并不能随心所欲。他们必须按地面营养师为他们配制好的食谱用餐。美国航天飞机上的宇航员吃饭时,先把标有第几天第几顿字样的塑料袋从食品柜中取出。每个塑料袋里装有7种食品,供一名宇航员食用。太空食品均为脱水食品,临吃前可把食物放入一个碗形的容器中,再用注射器将一定数量的水注进容器,然后再放进烤箱里加热。一顿饭不超过半小时就可以“做”好。 非同一般的吃饭动作 太空餐桌是特制的。它具有磁性,能吸住刀、叉、勺、碗、盘等餐具,桌上装有水冷却器和加热器。吃饭时,宇航员必须先把脚固定在地板上,把身体固定在座椅上,以免飘动。面对摆在餐桌上的饭菜,你千万不要着急,一定要注意端碗、夹饭、张嘴、咀嚼一连串动作的协调。端碗要轻柔,动作太猛,饭会从碗里飘出去;夹饭、夹菜要果断,夹就要夹准、夹住,最好不要在碗里乱拨拉,以免饭菜飘走,使用叉子效果最好;饭菜夹住后,张嘴要快,闭嘴也要快,因为即使是放到嘴里的食物,不闭嘴它也会“飞”走;咀嚼时节奏要放慢,细嚼慢咽利于消化,还可以减少体内废气的产生和排泄,避免宇航员生活环境的污染。 有些人最喜欢在吃饭时聊天神侃,而在太空吃饭最忌讳的就是边吃边说。边吃边说会使嘴里嚼碎的食物碎末飞出嘴外,飘在餐厅或生活舱里,宇航员稍不注意吸进鼻腔就容易呛到肺里发生危险。 特制的“王太太炒羊肉” 尽管太空食品供应充足,花样齐全,营养丰富,但宇航员却普遍抱怨在天上吃饭吃不出味道。科学家分析,原因可能不在食品本身,而是太空环境引起宇航员的味觉失调。如失重使鼻腔充血,导致味觉神经钝化,唾液分泌发生变化影响味觉,或者因为看不到食物的颜色、闻不到食物的气味而影响味觉。美籍华人宇航员王赣骏乘航天飞机上天时,为了使他能有个好胃口,他的太太做了他平时爱吃的炒羊肉。这道食品被命名为“王太太炒羊肉”。 糊涂觉与奇异睡姿 宇航员在太空中睡觉的的确确是“糊涂觉”,其表现一是黑白不分,二是睡姿奇异。 黑白不分,是说宇航员在天上绕地球航行,太空日出日落由航天器绕地球一圈的时间而定。有时24小时内日出日落交替许多次,宇航员无法遵循地球上“日出而作,日落而息”的生活习惯,只好机械地按钟点安排工作和睡觉。 睡姿奇异,是说宇航员在太空失重环境中找不到“躺”的感觉。在地球重力环境,人们习惯于把地心引力的方向定为“下”,把“天”的方向定为“上”,也就是人们常说的“脚踩大地,头顶蓝天”。可是到了失重的环境里,人们失去了“上”“下”的参照坐标,脚踩不到地,四周全是天,你根本分不清上、下,因此,睡觉也就没有了“平躺”一说。由于无论站着、躺着,还是趴着都可以入睡,所以宇航员睡觉可以飘在太空舱里睡,挂在墙上睡,绑在床上睡,也可以吊在梁上睡,靠在桌边睡。 不过大多数宇航员不习惯飘荡着睡。一旦从飘浮睡眠中醒来,他们会产生一种掉进万丈深渊的感觉。为了获得安全感,宇航员一般睡在固定的床上或固定在墙壁上的睡袋里,睡袋拉紧后能给人体施加一定的压力,使人消除那种飘飘欲坠的恐慌感。 千万别把手脚伸出被外 有人睡觉习惯把手或腿放在被子外面。这在地面上看来是很正常的现象,可是在太空环境里,却是很危险的。太空失重,睡眠中人的四肢会不受躯干支配而四处飘动。一名前苏联宇航员有一次把手臂放在睡袋外睡觉,醒来后突然发现有两只大手向他脸上飘来,吓了他一大跳。原来这飘动的两只大手正是他自己的手。吓一跳还是小事,如果宇航员睡着后,失控的“自由”之手、“自由”之脚万一无意中碰到了什么开关、什么仪器,那太空舱的安全、宇航员的生命岂不成了大问题?所以,在太空中睡觉,千万注意把手、脚放进睡袋里。 奇特的洗脸和刷牙 由于太空的失重环境,在地球上看似简单的洗脸、刷牙、刮胡子、理发以及洗涤,到了太空都变成了很复杂和麻烦的事。 宇航员洗脸刷牙比较奇特,为了防止水到处乱飘,一般用湿毛巾擦一擦脸就算是洗脸了;刷牙时,用手指蘸上牙膏来回蹭几下,然后再用湿毛巾把牙齿擦干净刷牙就算完成。如果像在地面上那样刷牙,牙膏泡会飞得满座舱都是。宇航员刮胡子一般使用电动剃须刀,使用时还必须十分小心胡子渣从剃须刀边漏出来。太空舱本来就十分狭小,环保问题就显得极为重要。如果细小的胡渣飘在座舱里,清理起来会十分困难。 太空理发也很不容易,因此无论男女宇航员在上天之前都要把头发理得短些再短些。但是长时间的飞行,头发又会长长,怎么办?宇航员必须发扬团结精神互相帮助,一人理发,一人拿着吸尘器吸走剪下的头发。 “桑拿室”和“洗浴袋” 在太空中洗澡更为麻烦。宇航员要把脚套在一个固定的环里,不然飘浮的身体被水一冲会不停地翻跟头。失重状态下的水全是一粒粒的小水珠,很容易呛伤人,甚至呛死人,所以洗澡时,宇航员还要戴上呼吸罩和护目罩。洗完澡后,身上的污水不会自动流下来,需要开动水泵连同空气一起抽走。沾在帆布罩上的水也得用水泵抽走。洗一次澡,真正的洗澡时间只有15分钟,可清理污水和其他准备工作却需45分钟。 后来,科学家对太空浴室进行了一些改进。比如俄罗斯和平号空间站的浴室像是一间桑拿室。宇航员进去后经过一段升温,使身体出汗,然后用湿毛巾擦洗。由于不方便也不舒服,“桑拿室”又改成了一个像睡袋一样的装置。宇航员洗澡时,袋内有清水和浴液射出,搓洗完毕后,可以打开袋下的抽风机,把脏水抽走。美国航天飞机上的浴室是个浴罩,浴罩下部也安有抽风机。宇航员洗澡时打开淋浴龙头和抽风机,上面喷水下面抽水,会形成如同地面一样的淋浴效果。 太空专用洗发液 宇航员的洗发液是特制的。这种洗发液96%的成分是从植物中提取的。由于在太空中不可能有很多的水供给宇航员冲洗头发,所以宇航员使用的洗发液是免冲型的。它在失重的状态下能变为十分细小的颗粒。洗头时,它很容易带走头上的污垢。洗完后,用餐巾纸或毛巾一擦,洗发液就被清除得一干二净。用这种太空洗发液洗过的头发,完全不用发胶、摩丝和吹风机,既能显示头发的自然美又特别容易梳理。 据最新报道,俄罗斯和美国专家正在为两国宇航员准备最新洗漱用品,但是他们在女宇航员的化妆品上产生了分歧。俄罗斯专家认为在太空完全没有必要打扮,而美国专家却认为香水、润肤液、口红等都是不可缺少的。(《中国国防报》 9月27日)

太空探索议论文题目有哪些

奇妙的星空 未来之旅 太空探险的卓越 幻想星球精神等等

读幼儿园时,我常喜欢跟着父母一起看《西游记》,每当看到孙悟空凭借腾云驾雾的本领,在人间与仙境之间来去自如,我会羡慕不已。常常幻想自己能长出一对翅膀,像小鸟一样,在天空中自由飞翔。因此我夜日有所思,夜有所梦。晚上,我常梦见自己脚一蹬,就飞到仙境吃仙桃,飞到月宫去玩耍。这对于年幼时的我来说,又香又甜的梦。我常手舞足蹈地把这个美梦告诉爸爸妈妈,他们总是说:“傻孩子,你想多了,你没有翅膀,怎么能飞上天呢?那时,我多么渴望长出一对大翅膀呀!”上小学了,老师跟我们讲关于人类上天的故事,又勾起了我的飞天梦。老师的讲解使我明白了:人类在我父母还没出生前就突现了上天的梦想,1961年4月12日,苏联宇航员加加林驾驶东方1号飞船,花了1小时48分的时间绕地球飞行1圈后安全返回,完成了人类首次太空飞行的任务,接下来的几十年里,苏联和美国的宇航员不仅完成太空行走的任务,而且登上月球,并成功建立了国际空间站。这些钩起了我育时的飞天梦。我的飞天梦变成了航天梦,我多么想到月球上去漫步,看看月球上是否有月宫,宫中是否有美丽的嫦娥仙子和活泼机灵的小玉兔。谈及航天,我想说:我们的国家在航天技术方面也是不甘落后的。航天技术虽然起步晚,但进步很快,“神州七号”就是中国的国力一个很好的体现。2008年,“神州七号”载着翟志刚、刘伯明、景海鹏三位叔叔绕地球46圈后,于9月28日安全返回,实现了继俄罗斯和美国之后,世界上第三个独立以本国研制的太空飞行器把本国宇航员成功送入太空的国家,我看到那激动人心的出舱镜头,心里是多么自豪!这一刻,我多想成为一名宇航员,坐着自制的飞船去探索宇宙的奥秘。想着想着,我迷迷糊糊地入睡了,在梦里,我乘着“勇敢飞天号”在地球穿梭,美丽的地球表面上那蓝色的海洋,绿色的大地,也看到了寸草不生的沙漠。当我正陶醉在美丽的景色之中,我就接到了指挥部的出舱命令,我怀着激动的心情走出的舱外,去完成这项艰巨而光荣的任务—登月。任务有两项,一是带着两类种子到月球上培育,一类是植物种子,另一类是粮食种子。如果培育成功,它们将使地球上茫茫的沙漠变成绿洲,荒凉的戈壁变成良田,处于饥饿的人们过上丰衣足食的生活;第二项任务是:在月球上发射一颗能预报地球上自然灾害的卫星,使可怕的海啸不再吞食人类的生命,使四川省汶川县的地震惨景不再重演。我欣然地接受任务并在月球上工作了半年多,成功地完成了指挥部交代的任务后,总部命令我返回地球,着陆时受到了人们的热烈欢迎,小朋友送我鲜花,老师和同学向我招手,爸爸、妈妈也高兴地站在我身旁,我沉浸在无比自豪和幸福中。突然,妈妈把我叫醒了,人虽然醒了,但脑子里全是那充满神奇的航天梦,我把梦告诉了妈妈,还跟妈妈说:“如果这梦竟能成为现实,那该多好呀!”,妈妈说:“孩子,只要你有决心,从现在开始准备,妈妈相信总有一天,你的梦会成真。”妈妈语重心长的告诉我:“中国的航天技术在不断发展,不是为了和他人竞争,而是在一步步地进行自己的宇宙探索,更好地为人类作贡献,接下来还要实现登月和建立空间站等目标呢!”,我好奇地问妈妈:“建立空间站有什么作用呢?”“这是一个提供给科学家、宇航员做科学试验的场所,现在人类已登上月球,正瞄准火星呢!”妈妈说。听着妈妈说的话,我若有所思:从现在起,我要坚持锻炼身体,努力学习,为长大后成为一名中国航天员作准备。我相信在不久的将来自己会与同行一起在空间站里共同合作,探索宇宙奥秘,飞到更遥远的星球,实现我的航天梦。

以航天为主题的题目如下:《弘扬航天精神 拥抱星辰大海》、《弘扬航天精神,拥抱碧空大海》、《弘扬航天精神,拥抱北斗卫星》、《世界航天日,重温这些航天高光时刻》、《探索浩瀚宇宙梦想的远航、创新的跋涉》、《航天精神一以贯之、历久弥新》、《千年天问,一朝梦圆 》。航空航天介绍:中国发展航天事业的宗旨是:探索外太空,扩展对地球和宇宙的认识;和平利用外太空,促进人类文明和社会进步,造福全人类;满足经济建设、科技发展、国家安全和社会进步等方面的需求,提高全民科学素质,维护国家权益,增强综合国力。中国发展航天事业贯彻国家科技事业发展的指导方针,即自主创新、重点跨越、支撑发展、引领未来。航空指飞行器在地球大气层内的航行活动,航天指飞行器在大气层外宇宙空间的航行活动。航空航天大大改变了交通运输的结构,航空航天的发展虽然与军事应用密切相关,但更为重要的是人类在这个领域所取得的巨大进展,对国民经济的众多部门和社会生活的许多方面都产生了重大影响。
