國際太空站 (ISS) 將於 2030 年最後一次返回地球

國際太空站自 2000 年以來一直被佔用，作為獨特的微重力實驗室進行了數千項實驗，也是來自世界各地太空人的家園。

After nearly two decades of groundbreaking scientific discoveries and serving as a beacon of international collaboration, the International Space Station (ISS) is nearing the end of its remarkable journey. In a recent development, NASA has entrusted Elon Musk's SpaceX with the critical mission of safely deorbiting the ISS and guiding it to a controlled re-entry over the vast Pacific Ocean.

經過近二十年的突破性科學發現並成為國際合作的燈塔後，國際太空站 (ISS) 即將結束其非凡的旅程。在最近的一項進展中，美國宇航局(NASA) 委託埃隆·馬斯克(Elon Musk) 的SpaceX 承擔一項關鍵任務，即安全使國際太空站脫離軌道並引導其在廣闊的太平洋上空受控重返。

Throughout its exceptional history, the ISS has been continuously inhabited since 2000, hosting thousands of groundbreaking experiments in its unique microgravity environment. Astronauts from around the globe have called the station their home, conducting invaluable research and pushing the boundaries of human spaceflight. However, as the station's aging components and expiring international agreements necessitated a decision, the responsible and controlled decommissioning of the ISS has been meticulously planned.

縱觀其非凡的歷史，國際太空站自 2000 年以來一直有人居住，在其獨特的微重力環境中進行了數千項開創性的實驗。來自世界各地的太空人將這個太空站稱為自己的家，進行寶貴的研究並突破人類太空飛行的界限。然而，由於國際太空站的老化部件和即將到期的國際協議需要做出決定，國際太空站負責任且受控的退役已經經過精心規劃。

SpaceX's role in this endeavor will involve developing and operating a specialized spacecraft, known as the United States Deorbit Vehicle (USDV). This USDV is meticulously designed to seamlessly integrate with the ISS, enabling its thrusters to gradually lower the station's orbit. Through this controlled descent, the USDV will ultimately guide the ISS into Earth's atmosphere for a controlled re-entry.

SpaceX 在這項工作中的角色將包括開發和營運一種名為美國脫軌飛行器 (USDV) 的專用太空船。這款 USDV 經過精心設計，可與國際太空站無縫集成，使其推進器能夠逐漸降低太空站軌道。透過這種受控下降，USDV 最終將引導國際太空站進入地球大氣層，進行受控重返大氣層。

To ensure the safety of populated areas and minimize any potential risks, the final re-entry trajectory is carefully calculated. The remaining debris from the ISS is expected to fall into a remote region of the Pacific Ocean, a deliberate measure to mitigate any possible impact on landmasses. This entire process strictly adheres to established international space debris mitigation guidelines.

為了確保人口稠密地區的安全並最大程度地減少任何潛在風險，最終的重返軌道是經過仔細計算的。國際太空站的剩餘碎片預計將落入太平洋的偏遠地區，這是減輕對陸地可能影響的故意措施。整個過程嚴格遵守既定的國際太空碎片減緩準則。

As the world bids farewell to the ISS, it marks not only the conclusion of an era in space exploration but also the opening of new frontiers. NASA is pivoting its focus towards commercial space stations in low Earth orbit, paving the way for a new era of collaboration between government agencies and private companies in the thrilling realm of space exploration.

隨著世界告別國際太空站，這不僅標誌著太空探索時代的結束，也標誌著新領域的開啟。美國太空總署 (NASA) 正在將重點轉向近地軌道商業太空站，為政府機構和私人公司在令人興奮的太空探索領域合作的新時代鋪平道路。

The enduring legacy of the ISS serves as a testament to the remarkable achievements possible through international cooperation in science and technology. This collaborative spirit is further exemplified in the efforts to safely deorbit the ISS, ensuring a responsible conclusion to this extraordinary chapter in the annals of space exploration.

國際太空站的不朽遺產證明了透過國際科學技術合作可能取得的非凡成就。這種協作精神在國際太空站安全脫離軌道的努力中得到了進一步體現，確保為太空探索史上的這一非凡篇章畫上負責任的句號。
