现在最无力的预测是4月1日,美国非营利构造航空航天公司估量天宫一号能够在西班牙,但是详细的所在难以确定,国度航天局公布的网上通告称,用来测试与其他飞船对接并停止一系列实行
  

The current best prediction is 1 April (no, this is not an April Fool’s joke). 现在最无力的预测是4月1日(这可不是哲人节打趣)。 But again, because of its speed, it could be at least a day either side of that. 但是,由于天宫一号在废弃时处于高速运转中,也能够是4月1日的前后两天。 The Aerospace Corporation, a nonprofit organization in the United States, estimated that the re-entry of Tiangong I would occur over Spain, France or Portugal, though an exact location is still hard to pinpoint. 美国非营利构造航空航天公司估量天宫一号能够在西班牙、法国或葡萄牙境内坠落,但是详细的所在难以确定。 No. The chances of being hit by part of the space station are basically zero. 没须要。被天宫一号的残片击中的能够性简直为零。 In terms of size, Tiangong-1 is only the 50th largest spacecraft to come down, and there have been no recorded deaths or injuries from people being struck by debris from any of them. 在废弃的航天器外面,天宫一号的体积仅排在第50位,而此前没有任何记载表现有人被废弃的航天器碎片击中并招致伤亡。 However, a highly toxic and corrosive substance called hydrazine, which is often used in creating potent rocket fuel, can potentially survive re-entry. 但是,坠落进程中能够有一种名为联氨的剧毒腐化性物质会残留在碎片上,这种物质常被用来制造火箭推进剂。 "For your safety, do not touch any debris you may find on the ground or inhale vapors it may emit," an online statement released by the space agency said. 国度航天局公布的网上通告称:“为了平安起见,请不要触碰地上的航天器碎片,也不要吸入碎片分发的气体。” It was launched unmanned but was designed to be habitable, to test docking with other craft, and to be used for conducting experiments. 天宫一号发射的时分没有载人,但是设计初志是可载人的,用来测试与其他飞船对接并停止一系列实行。 Tiangong I had completed six space rendezvous and docking missions with three visiting spacecraft. The first visit was by an unmanned spacecraft called Shenzhou VIII in November 2011, as part of China's first space docking mission. 天宫一号曾经完成了6次空间交会,并和3艘飞船完成了对接。第一次对接是在2011年11月与神舟八号无人飞船对接,这也是中国初次太空对接义务的一局部。 The second and third missions were both manned: Shenzhou IX in June 2012 and Shenzhou X in June 2013. Both manned missions had three astronauts and lasted about two weeks, during which the astronauts tested the station's various systems and living conditions. 第二次和第三次对接义务都是载人交会对接义务,辨别是在2012年6月与神舟九号对接,以及在2013年6月与神舟十号对接。两次载人航天义务都有三名宇航员,工夫继续约两周,在这时期航天员测试了空间站的各个零碎和生活条件。
