凯时kb88,天舟一号Tianzhou-1Chinahastakenanothersteptowarditsgoalofputtingaspacestationintoorbitaround2022,bysendingitsfirstcargospacecraftTianzhou-1intospaceonThursdayevening.我国首个货运飞船天舟一号于20日晚发射升空,我们朝着2022年前后建立轨道空间站的目标又迈进了一步.AtopaLongMarch-7Y2carrierrocket,Tianzhou-1roseintotheairfromtheWenchangSpaceLaunchCenterinsouthChinasHainanProvinceat7:月20日19时41分,搭载着天舟一号货运飞船的长征七号遥二运载火箭,在我国文昌航天发射场点火发射.天舟一号(Tianzhou-1)是我国自主研制的首艘货运飞船(thefirstcargospacecraftdevelopedbyChina),也是中国目前为止体积最大、重量最重的航天器(thelargestandheaviestspacecraft).由于它只运货,不送人,所以被形象地称为太空"快递小哥"(spacecourier/deliveryman).天舟一号采用两舱式结构,直径较小的是推进舱(propellingmodule),直径较大的为货物舱(cargomodule).飞船全长米,最大直径米,起飞质量(takeoffweight)约13吨,太阳帆板展开后最大宽度米,物资运输能力(payloadcapacity)约吨,推进剂补加能力约为2吨.Tianzhou-1smostcapablecargospacecraftinservice:JapansH-IITransferVehiclehas6tonsofpayloadcapacity;theCygnusandDragon,bothUS-madecraft,;andRussia天舟一号吨的物资运输能力使其成为世界上运输能力最强的现役货运飞船:日本的H-II货运飞船运输能力为6吨;美国的"天鹅座"和"龙"飞船的运输能力分别为吨和吨;俄罗斯的进步-MS飞船为吨.天舟一号在太空要执行哪些任务?飞船入轨后,将按预定程序与在轨运行的天宫二号先后进行自动交会对接(autonomousdocking)、自主快速交会对接(autonomousfastdocking)等3次交会对接,3次推进剂在轨补加(propellantin-orbitrefueling)以及空间应用和航天技术等领域的多项实(试)验.首次对接:两天后,天舟一号与天宫二号进行首次交会对接.之后,天舟一号与天宫二号组合体将进行为期两个月的在轨飞行.期间,计划完成3次推进剂在轨补加试验(experimentsonpropellantin-orbitrefueling),同时测试货运飞船对组合体的控制能力(testthecontrollingabilityofthecargospacecraftoverthetwospacecraft).二次对接:完成首次对接后,天舟一号与天宫二号分离,然后绕飞到天宫二号的另一侧,进行第二次对接.第二次对接的主要任务是进行绕飞实验(fly-aroundtests),检验天舟一号前向对接能力(capabilityofforwarddocking).之后天舟一号与天宫二号再次分离,两个飞行器将独立飞行三个月,完成搭载的空间科学试验(spacescientificexperiments).三次对接:天舟一号与天宫二号进行最后一次对接,验证自主快速交会对接(autonomousfastdocking)技术,要求在六小时左右实现对接.完成所有既定任务后,天舟一号将受控离轨,陨落至空间安全海域(fallintoadesignatedseaarea).此次任务是中国载人航天工程空间实验室阶段(spacelaboratorystageofChinamannedspaceengineering)的收官之战,对于空间站工程后续任务顺利实施具有极为重要的意义,将标志着中国载人航天工程胜利完成"三步走"战略中的"第二步"任务,为空间站建设任务奠定坚实技术基础.1992年9月,中国实施载人航天工程并确定中国载人航天"三步走"的发展战略(three-stepmannedspaceprogram):第一步,发射载人飞船(mannedspaceship),建成初步配套的试验性载人飞船工程,开展空间应用实验.2013年神舟5号载人飞船任务顺利完成.第二步,突破航天员出舱活动技术(extra-vehicularactivity)、空间飞行器的交会对接技术(rendezvousanddocking),发射空间实验室(spacelab),解决有一定规模的、短期有人照料的空间应用问题.第三步,建造空间站,解决有较大规模的、长期有人照料的空间应用问题(operateapermanentmannedspacestation).
