天宮一號將再入大氣層燒燬 這些問題可能是你關心的大綱
天宮一號會在什麼時間燒燬？
The current best prediction is 1 April (no, this is not an April Fool’s joke).
目前最有力的預測是4月1日（這可不是愚人節玩笑）。
But again, because of its speed, it could be at least a day either side of that.
但是，因爲天宮一號在燒燬時處於高速運轉中，也可能是4月1日的前後兩天。
天宮一號的殘片最可能落在哪裏？
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.
美國非營利組織航空航天公司估計天宮一號可能在西班牙、法國或葡萄牙境內墜落，但是具體的地點難以確定。
我們會不會被殘片砸中？
No. The chances of being hit by part of the space station are basically zero.
沒必要。被天宮一號的殘片擊中的可能性幾乎爲零。
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.
在燒燬的航天器裏面，天宮一號的體積僅排在第50位，而此前沒有任何記錄顯示有人被燒燬的航天器碎片擊中並導致傷亡。
However, a highly toxic and corrosive substance called hydrazine, which is often used in creating potent rocket fuel, can potentially survive re-entry.
然而，墜落過程中可能有一種名爲聯氨的劇毒腐蝕性物質會殘留在碎片上，這種物質常被用來製造火箭推進劑。
"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.
國家航天局發佈的網上公告稱：“爲了安全起見，請不要觸碰地上的航天器碎片，也不要吸入碎片散發的氣體。”
天宮一號在太空都做了些啥？
It was launched unmanned but was designed to be habitable, to test docking with other craft, and to be used for conducting experiments.
天宮一號發射的時候沒有載人，但是設計初衷是可載人的，用來測試與其他飛船對接並進行一系列實驗。
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.
天宮一號已經完成了6次空間交會，並和3艘飛船實現了對接。第一次對接是在2011年11月與神舟八號無人飛船對接，這也是中國首次太空對接任務的一部分。
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.
第二次和第三次對接任務都是載人交會對接任務，分別是在2012年6月與神舟九號對接，以及在2013年6月與神舟十號對接。兩次載人航天任務都有三名宇航員，時間持續約兩週，在這期間航天員測試了空間站的各個系統和生存條件。
