SpaceX的貨運龍飛船（Dragon）在維持國際太空站（ISS）運作方面扮演著至關重要的角色。
SpaceX's Cargo Dragon spacecraft plays a vital role in maintaining operations at the International Space Station (ISS).
不同於其他在重返大氣層時會燃燒殆盡的補給載具，龍飛船是唯一能夠將重型設備與科學實驗品帶回地球的美國貨運太空船。
Unlike other resupply vehicles that burn up upon re-entry, the Dragon is the only U.S. cargo ship capable of returning heavy equipment and scientific experiments back to Earth.
這項能力對於需要對在微重力環境下處理過的樣本進行詳細實驗室分析的研究人員來說至關重要。
This capability is crucial for researchers who need to conduct detailed laboratory analyses on samples, such as bioprinted tissues and stem cells, that were processed in microgravity.
在與國際太空站脫離後，太空艙會執行脫軌燃燒以重返地球大氣層，並由專門的隔熱罩保護。
After undocking from the ISS, the capsule performs a deorbit burn to re-enter Earth's atmosphere, protected by a specialized heat shield.
一旦被SpaceX團隊回收，對時間敏感的生物樣本會迅速交付給科學家，通常在48小時內送達。
Once recovered by SpaceX teams, time-sensitive biological samples are quickly delivered to scientists, often within 48 hours.
透過NASA的商業補給服務，這些任務定期進行，藉由重複使用獵鷹9號（Falcon 9）推進器與龍飛船本身，支持永續的太空旅行。
Through NASA's Commercial Resupply Services, these missions occur regularly, supporting sustainable space travel by reusing both Falcon 9 boosters and the Dragon capsules themselves.
除了補給之外，龍飛船已進化到能協助太空站維護，例如執行推進補給以保持國際太空站處於正確軌道，這凸顯了商業合作在現代太空探索中的關鍵作用。
Beyond resupply, the Dragon has evolved to assist in station maintenance, such as performing reboosts to keep the ISS in its proper orbit, highlighting the critical role of commercial partnerships in modern space exploration.
