第二部分:课题研究成果
一、引言。
从17世纪开始,古老的梦想与发轫期的近代自然科学相遇,诞生出一系列具有强烈科学性的幻想小说。德国天文学家开普勒在1634年出版的《梦游》中第一次对月球旅行展开幻想,法国作家贝尔日拉克在《月球之旅》中用近似科学的态度讨论了太空旅行中的各种飞行方法,法国作家凡尔纳更是在其名作《从地球到月球》中大胆地把巨型炮弹作为未来的航空器,并运用大量的数学、物理学和天文学知识,对炮弹和发射装置进行了严格的计算。
科学,如同孕育在幻想中的胎儿,吮吸着幻想的营养一天天成长。1903年,人类飞天史上的一个里程碑。那一年,莱特兄弟驾驶着他们在自行车修理车间里制造的第一架飞机“飞行者1号”,实现了人类历史上第一次成功的空中飞行。
同样在这一年,双耳失聪的俄国科学家齐奥尔科夫斯基在论文中提出了著名的“火箭公式”,论证了用火箭发射航天器的可行性。他指出:最理想的推进剂不是火药,而是液体燃料;单级火箭在当时达不到宇宙速度,必须用多级火箭接力的办法才能进入宇宙空间。
“地球是人类的摇篮,但是人类不会永远生活在摇篮里,开始他们将小心翼翼地穿出大气层,然后去征服太阳系。”齐奥尔科夫斯基说。
正是凭着这位“航天之父”的天才构想,一扇通往太空的科学之门打开了。
二、研究方法
成员分工以网络及图书馆书籍查找有关资料,并对其进行汇总、筛选、加工,成员根据其结果讨论分析。
三、研究结果。
★1957年10月,在哈萨克的大荒原里,前苏联用火箭把第一颗人造地球卫星“斯普特尼号”送上了天。这颗直径580毫米、太空运行仅92天的小卫星,宣告着人类进入到一个空间探索的新时代。
此时,人类东西方的冷战已持续了10多年。今天,我们不可否认的是,虽然人类纯洁的飞天梦因为承载了超级大国的政治野心而变得有些沉重,但地球上两个强国之间的竞争也让人类积蓄了数千年的能量在瞬间得以爆发。
★1961年4月,在9次无人飞船试验后,“东方1号”飞船载着27岁的前苏联空军少校加加林,进行了108分钟的太空旅行。这是人类历史上第一次载人航天飞行,加加林也成为人类造访太空的第一人。
★同年,美国启动“阿波罗登月计划”。8年之后的7月21日,美国宇航员阿姆斯特朗就在月球上留下了人类的第一个足印。在踏上月球的一刻,人类第一位月宫使者由衷慨叹:这是个人的一小步,却是人类的一大步。
“一小步,一大步”,人类就是这样一步步地探索着飞上九霄——
★1971年4月,前苏联成功发射了世界上第一个试验性载人空间站——“礼炮1号”空间站。载人航天活动由此进入到规模较大、飞行时间较长的空间应用探索与试验阶段。
★1975年7月,前苏联的“联盟19号”飞船和美国“阿波罗18号”飞船,在太空中成功对接。通过电视转播,全世界数以亿计的观众目睹了来自两国的两位太空使者相拥的历史画面。
★1981年4月,美国发射了可以重复使用的太空运载工具——航天飞机。6年后,美国邀请欧洲航天局、日本和加拿大参加研制永久性载人空间站计划。1993年,俄罗斯的加入不仅扩大了空间站的规模,而且使这个项目成为一项真正意义上的国际性计划……
陷入疲惫竞赛的载人航天活动,似乎又找到了人类梦想的初衷。
国际空间站,一个共同探索、和平开发宇宙的平台。从飞船到空间站,人们用不懈的探索搭建起了通往“天宫”的云梯。
然而,通天之路从来充满艰辛——
★1971年6月,前苏联3名宇航员在飞船气压阀失效时因为缺乏航天服的保护而死亡;
★1986年1月,美国“挑战者号”航天飞机起飞后凌空爆炸,7名壮志未酬的宇航员、包括一位即将在太空中为几十万美国中学生讲授奇妙太空的中学教师,在万众瞩目中献身蓝天;
★2003年2月,美国“哥伦比亚号”航天飞机在它的第28次飞行返程途中突然解体,再过16分钟就能踏上地球的7名宇航员全部牺牲;
★2003年的8月,巴西第三枚VLS型卫星运载火箭在发射前的最后检测中发生爆炸,“咖啡王国”的航天梦再次遭受重创……
★1970年4月24日,中国第一颗人造卫星发射成功。
★33年后的10月15日,“长征二号F”型火箭托举着神舟五号载人飞船轰然起飞。
★2005年金秋,中国第二次载人航天飞行起航。
并且,我组成员对我国的航天做了进一步的了解:
在人类大步迈向太空的旅程中,中国人追梦的步伐一天也没有停止过。1970年4月24日,中国第一颗人造卫星发射成功。
那一年,胡世祥30岁,是按下发射“东方红一号”卫星火箭点火按钮的操作手;戚发轫37岁,是“东方红一号”卫星的技术负责人。
33年后的10月15日,他们分别以中国载人航天工程副总指挥和载人飞船系统总设计师的身份,出现在中国首次载人航天飞行的指挥大厅里。
9时整,“长征二号F”型火箭托举着神舟五号载人飞船轰然起飞。浩瀚太空迎来了第一位中国访客——38岁的中国航天员杨利伟。在343公里的高度上,中国人第一次在自己的航天器上看到了人类美丽的地球家园。
这是中国的高度,一个崇尚独立自主的民族以自己的方式叩问天宇的高度。
从这一天起,中国成为继俄罗斯、美国在世界上第三个能够独立开展载人航天活动的国家。戚发轫说,梦圆那刻,是他这一生笑得最灿烂、哭得最痛快的一次。
神舟五号的顺利升空,不仅仅使得中国人的千年飞天梦想变为现实,更重要的是它标志着在人类探索太空的队伍中,又加入了一支强大而富于创造性的力量。
在太空建立实验室的近期目标,以及太空开发的无穷远景,令所有的中国航天人,令所有爱好梦想的中国人,愉快地幻想并热切地期待着。
2005年金秋,中国第二次载人航天飞行起航。专家一开始就预测,如果这次任务能够顺利完成,下一步中国载人航天的目标将是航天员出舱进行太空行走……
——梦想有多远,我们的足迹就有多远。
四、讨论与分析。
从事太空研究的好处是可激发人类的探索发明精神,刺激高科技技术和工艺的发展,促进新技术与新产品的应用,不断改善和提高人类生活水平与质量。就拿环球飞行来说,正是宇航员在太空才发现我们居住的地球,在浩瀚的太空中显得多么渺小和脆弱。宇航员们用遥控设备发现,是厚厚的大气层和磁场保护了人类免受各种辐射之害,同时地球表面的变化也告诫人类,应该认真保护环境和善待地球。也正是这些发现导致16个国家合作建立了国际空间站,共同开发空间技术,探索宇宙和未来。而有此共识是人类发展和自我意识提高的关键一步。
被人类称作“天堂”的蔚蓝色苍穹是如此的广袤、深邃、神秘和美丽,以致吸引了人类世世代代的强烈关注,也促发了人类生生不息的探索。在人类大步万向太空的旅程中,中国人追梦的步伐一天也没有停止过。如今,中国有了自己的航天技术——
——中国已形成12个型号的“长征”系列运载火箭。未来的新一代大推力运载火箭,将满足不同用途大型卫星和空间站的发射需要;
——中国已初步形成了返回式遥感卫星、通信广播卫星、气象卫星、科学探测与技术试验卫星、地球资源卫星、导航定位卫星等多种类型的卫星系列。将来,中国还要建立长期稳定运行的卫星对地观测体系,自主的卫星导航定位系统,以及产业化、市场化的空间应用体系;
——中国已启动无人月球探测的“嫦娥工程”,那轮在唐诗宋词里无数次被吟诵过的月亮,就要迎接来自中国的亲密接触……
在跨越式地实现了载人航天工程的第一步目标之后,中国正在稳步走向以交会对接为特征的第二步和更远的未来。中国的航天专家们已经在计划着实现载人航天后,着手建立太空实验室,建立包括永久性空间站在内的“地面——太空综合网”,将大型空间站发展成为空间航天基地……
第三部分:研究性学习的心得
通过这次的研究性学习,让我更深入的了解到了宇宙的浩瀚无穷。
可以说这次的研究性课题的过程是艰维的。在一无所知的情况下,想要探索太空的奥妙、历程,少不了要挥洒辛勤的汗水。这一路上,老师的指导带着我们的努力,终于看到了胜利的曙光,呵,是该觉得庆幸啊!
还记得起初说课题研究的课题是“探索太空历程”时,我们几个都蒙了。天哪!这该怎么办?其实事实就是这样,只要你去走,路就会在脚下延伸,如果你只是停留在原地的话,那事情将永远办不成功。不管是输还是赢,就当赌一把好了。总比原地踏步好。俗话不是说“这一秒不放弃,下一秒便会有希望”,说的不就是这道理吗?是的,我为我们当初没有因一点的困难而放弃感到无比的庆幸。
另外,通过这次的研究课题还使我明白了团结的力量,正因我们当初的团结一心,而使这课题取得了初步的成就,不是吗?团结就是力量!
以上便是我完成此研究性学习的心得与体会。
许妙丹
随着科学技术的发展,人类对太空的好奇心越来越大,探索未知成为人类进步的动力,而我们所了解的太空知识是少中之少的。因此了解航天技术的进程与探索太空的意义是非常重要的。我也想通过这次研究性课题对这方面问题有所了解,亲学习科学家们的探索精神。这有助于我们培养社会责任感,提高自己的文化知识水平。
在整个过程中,我们充满着自信与好奇。但毕竟我们都没有研究科学的经验,什么事情都必须虚心请教,再去寻找答案。如我们应该从何研究起,如何搜索答案,如何言简意赅地表达且进行分析总结等。最后在老师的指导和与我们的共同协作下,我们完成了课题。过程是艰维的,但心情是甜美的。因此我们都怀着喜悦耳的心情来庆祝我们的成功。
吴若虹
开展研究性学习的目的就是为了提高同学们的动手实践能力,让我们通过对宇宙的探索、学习得到更多有关的知识,从而开拓我们的视野。而我在参与这项研究性学习活动后确实是有很大的收获,我对太空有了更深一层的认识,也知道人们探索宇宙的艰辛,他们要面临各种随时都可能出现的挑战,有时甚至要以生命为代价的。但人们并没有因此而退缩,他们克服内心的恐惧、精神的压力,毅然踏上探索太空的旅程。这种通于挑战自我,将生死置之度外的精神是崇高而又值得我们学习的。而作为新世纪的接班人,我们应该认识到宇宙是广阔无边的,对它的探索将是永远无止境的。我们如今对它的认识还只是冰山一角,若想了解得更多,就应该从现在起跟随科学家的脚步,时刻关注宇宙的动态。

2026年美国计划把人类送入火星。
今年美国国家航空航天局(NASA)首次发布了详细的全天空宇宙微波背景辐射地图。证实宇宙大部分是由神秘的暗能量和暗物质组成的,并且给出了宇宙的确定年龄和精确的膨胀速度。
宇宙大爆炸发生后,早期宇宙是极高温度和极高密度的均匀气体,随着宇宙的膨胀,宇宙的温度会降低,当温度降低到退耦温度(Td=0.26eV,相当于3000K)以下时,质子与电子会复合生成氢原子并放出光子。当大多数自由电子被质子俘获后,光子就可以自由地在宇宙中传播,即宇宙对光子变得透明了,这就是我们能够观察到的宇宙中最古老的光,它携带了宇宙大爆炸后遗留下来的信息。由于宇宙学红移,我们现在观察到大爆炸后遗留下来光子频率的极大值已经移动到了微波波段,这就是宇宙微波背景辐射(CMBR, Cosmic Microwave Background Radiation)。
1992年,NASA曾发射过一颗宇宙背景探测者卫星(COBE)并观测到了宇宙微波背景辐射在不同方向上存在着微弱的温度涨落。为了进一步研究这种各向异性现象,今年NASA的威尔金森微波各向异性探测器(WMAP, Wilkinson Microwave Anisotropy Probe)第一次清晰地绘制了一张宇宙婴儿时期(大爆炸后不到38万年)的图像。这张清晰的早期宇宙图像标志着宇宙学进入了一个新的时代。
宇宙背景探测者卫星(COBE)观测结果
威尔金森微波各向异性探测器(WMAP)观测结果
宇宙的年龄大约是130亿年,38万年寿命宇宙的图像相当于一个80岁的人在他出生当天拍下的照片。
有了这一进展,以及今年一系列与之相关的其他进展,延续几十年关于“暗物质是否存在”的争论画上了句号。五年前,科学杂志的封面曾刊登了一张爱因斯坦的漫画:他看起来被1998年的科学发现“加速中的宇宙”惊呆了——两组天文学家在死亡阶段恒星发出的咔咔声中发现了一种可怕力量的蛛丝马迹。
一些明亮的超新星使得宇宙学家可以用之确定宇宙在不同时期膨胀的速度。科学家们惊讶地发现宇宙正加速膨胀着,膨胀速度越来越快,而不是象先前认为的减速膨胀。减速膨胀理论是广义相对论的自然结果,曾得到天体物理学家的普遍相信。这就是神秘的“暗能量”的首次登场,一种未知的力量抵抗着引力并把星系相互分开。
尽管来自超新星的数据是十分明确的,但许多宇宙学家仍然犹豫不决是否要支持“暗能量”这一古怪的概念。全世界的天文学家都迫不及待地采用不同的方法去验证这种不可避免的力是否存在。
今年,关于“暗能量是否存在”的争论已告结束,今后不会再有科学家去怀疑暗能量的存在性。他们将试图去解决暗能量是由什么构成的,它能提供哪些关于宇宙诞生和演化的信息等新问题。
残存的关于暗能量存在性的怀疑以及宇宙组成的问题已经在WMAP卫星描绘出迄今最清晰的宇宙微波背景(CMB, cosmic microwave background)辐射地图后而烟消云散。CMB是宇宙中最早的光, 是当新生宇宙还是一团炽热的等离子球体时所发出的光辐射。这种微弱的微波辐射弥漫在我们的周围,就像远处一堵火墙(wall of fire)发出的热辐射一样。记录在这面火墙上的信息就是微小的温度涨落(和其他一些性质),这提供了宇宙组成的信息。
在恒星和星系形成之前,宇宙是一团炽热发光的等离子体,引力与光的效应在那里激烈地竞争。大爆炸让整个宇宙振动并象钟一样发出巨响,压力波在等离子体内传播,挤压并拉扯着等离子体内的物质。
我和月亮有个约会
夜幕刚刚降临,月亮就像个又圆又大的气球挂在东方的天空。这是中秋的月吗?胖胖的脸蛋像个稚气可爱的娃娃。这怎么和那些浪漫的故事和优美的诗词联系得上呢?我不禁有些失落。
许多年没有这样从容、清闲地赏月了。要么是阴雨天;要么是被忙碌的学习和工作束缚;要么被俗事、烦恼所困扰,中秋节就那么匆匆而过。今年的中秋节,天气晴好,又没有杂事缠身,可以轻松地赏月了,真的很难得。就当今晚和月亮来个约会好了,就算月亮是个稚气孩子也没关系。
月亮的清辉已把大地照得一片朦胧,几个孩子踏着滑板,在楼群间的大道上飞也似地穿梭往来。月光下,飞速旋转的滑轮闪动着五彩的光,就像他们五彩的童年。我抬头看看月亮,不由笑了。做个稚气的孩子也不错,没有了成年人的浪漫,也就没有了成年人的哀愁。
八月十五明月夜,远方的朋友,你和谁共度呢?是和家人团团围坐,吃月饼赏月?还是和你的那个她或者他在月光下,来一次浪漫的约会呢?或许你正和一大帮好友参加热闹的中秋晚会,也可能和我一样独自在月下徜徉。
沉思间,月亮已经升高了,明亮了许多,也清瘦了许多,像个清逸的女子高高飞升在海一样的蓝天上。天空湛蓝澄澈,洁白的云朵像飞溅的浪花;天空深邃高远,让人忘了尘世的烦恼。真想化作一片白云,和月亮做伴,和清风嬉戏,就算融化在蓝天里也是快乐的。
“海上升明月,天涯共此时。”想着远方的亲友以及心中的那个她或者他也和自己一样沐浴在清风明月里,共享这同一轮圆月,心里就少了许多孤单和寂寞,多了宽慰和欣喜。“如果你问我爱你有多深?月亮代表我的心。”望着圆圆的月,想着他或者她对你满满的爱和关怀,是否会沉醉不知归路呢?而我看着头顶的圆月,一边想着月下的那些浪漫的故事和优美的诗句,一边在如梦如幻的月光下漫步,真的惬意极了。
回到家里,我意犹未尽,仍沉浸在月光下的遐想里。一缕明亮的月光从窗帘的缝隙里钻进来,我拉开窗帘,皎洁的月光一下泻在床上,把床照得一片雪亮。躺在床上,就可以看见窗外的月亮,它仍然那么亮,那么美。只是,在夜深人静的夜里,你孤零零地高悬在空旷的天空,不寂寞吗?
千百年来,许多名人、骚客也和我们一样头顶同一片蓝天,面对同一轮明月,把你反复吟唱,写下了流传千古的名句,寄托了多少思念、爱恋和清愁。你和山岳一样古老,你和新花一样年轻,千年不变美丽的容颜。人们仰望你,像在仰望一位女神。就算孤单寂寞也是值得的吧?我望着月亮问。月亮一下跳到我面前,凝视我,那么圆,那么大,那么亮,让我眩晕。我眯着眼睛,微微笑了,今晚有我相伴,你不会孤单了吧?我枕着如水的月光,朦胧睡去,安详得像一个婴儿。
今天我一回家就在电脑前做好准备,我按了电源又开了主机,手握着鼠标,静静的等着电脑的启动。
咦?谁把我的屏幕改成了一幅安静的天空?天空中还挂着一轮弯弯的明月。忽然,桌面闪出一个对话框,并显示出一行字:你好!我是月亮姐姐,今天我无聊极了,想和你聊聊天行吗?哈!不会吧,月亮姐姐?我忙回了:“你是天上的月亮吗?我电脑上的屏幕是你发的吧?”“是的,那可是我的照片,美吗?我想和你交朋友聊聊天”。聊天好啊!就这样聊啊聊着,我伸了个懒腰,又看了看天上:“今晚你值班吗?如果有的话,晚上能飞来我家跟我玩吗“?“不行的“,“为什么”?“天上仍是我们住有地方,也就是你们说的家,那儿有足够的一氧化碳让我们生活,而人间不适合我们生存”。“ 我明白了,我也不会再邀请你到我这做客了,你哪有吃饭吗?你吃了吗?肚子饿不饿?”月亮姐姐笑了笑说:“不饿,我们天上是不吃东西的,我也没尝过饿的滋味是什么,你呢?”“我刚吃完......咕噜--咕噜”,我还没说完,肚子就出卖我了,羞得我满脸通红。“哈!哈!哈!你的肚子可比你诚实多了,要不然你的肚子就不会这么抗议,这样吧,我请你吃天上佳肴,好不好?”“不是吧,你不是不吃的吗?怎么请客?”“等会儿你就知道了”顿时静了下来.我着急等着,手也不停打出:"月亮姐姐你在吗?"
当我正在着急时,哗,电脑桌面闪出一道强烈的五彩光,刺的我睁不看眼.当我睁开眼睛时,只见我的电脑前排着几颗金光闪闪的星星,几朵五颜六色的彩云。紧接着电脑上显示一行字:"吃吧,尝尝味道如何"这能吃的吗?我迫不及待的伸出手,拿起一颗星星狠狠的咬一口,咦!这是脆皮豆吗?又香又脆入口即化.谗的人直流口水。接着又抓起一朵五彩云,急塞入嘴里,‘棉花糖’不对‘QQ糖’也不对。不管了先吃了再说,哇噻!太好吃了!人间极品呀!
不知不觉,四周一片寂静,“哎呀,我差点忘了我还要值班呢,不聊了,谢谢你陪我聊天,我今天过的非常快乐。再见!”月亮姐姐下线了,桌面又恢复原来的样子。我禁不住抬头向天上望去。哦!我看到了月亮姐姐啦!她正对着我咪咪笑呢„„

《探索太空》英文读后感1Looking at dark sky at night for a while, you may see a red star.It has dazzling color.People call it “Mars”.In the solar system, beyond the third planet, the fourth one is “Mars”.It is a planet which is far away from Earth, about 2 hundred million kilometers on average.It is so charming that many scientists and people want to go there.Yes, distance lends enchantment to the view.Exploring space is not as easy as you might think.It is beyond your imagination.Scientists still make great contributions to exploring space and they also get good results.Space exploration is developing successfully.Scientists have made great progress with this project in only a few years’ time.In the past fifty years, people have launched many detectors into the unknown universe and planets.However, most of them ended with failure.These detectors still helped the scientists and people to know more about this science.The first time they launched the detectors to Mars was in 1960s.From then on, two super countries, America and the Soviet Union, started a competition to explore Mars.They never stopped launching detectors to Mars.Even if two thirds of them failed.However, it didn’t stop us from exploring space.Distance should not be an obstacle to exploring space.At the beginning of XX.NASA Launched two detectors to Mars, and both of them landed safty.They sent many useful information to Earth.It was really exciting news!Before that, a detector launched by Europe was lost in Universe.It was a shock to the scientific community, but they will never give up.As a matter of fact, the purpose of launching so many detectors to space is to find a planet with life and the basic element – water.The moon is far away from Earth, but it is the nearest star to Earth.People have been fascinated by the moon since ancient times until 1969 when astronauts from America landed on the moon.They found that the moon was just a satellite, without water, air, atmosphere and life, so people’s fantasies about moon were broken.The moon is a real “Wide-cold Palace”, it also has very bad weather, extremely cold at night and extremely hot during daytime.Nothing can subsist on the moon.When the astronauts landed on the moon, it was as if the distance went from 380 thousand kilometers to zero kilometers.All the beautiful fantasies and legends about moon were broken, so people now aim their eyes on Mars.They hope that one day the astronauts can step on Mars and realize our new dream.Since we know the truth of moon, it is not so tempting to us.But poems about the moon can still give us some yearning.Compare the beginnings of space travel with exploring space today.The exploration of space today is more useful.Many people are fond of Mars because among the nine planets in the solar system it is the most similar to Earth, so we call them “Brother Planets”.On Mars, there is a thin atmosphere lay and some oxygen.The detectors have found that there once exisited water.Due to the low gravity, the water all ran into space.The exploration of space is not only helping us know more about the unknown space, but also telling us a way to the new science and possibly a homeland.In other words, people may realize the dream of living on another planets.
