原文:
The International Space Station is the largest object ever constructed by humans in space. The station perimeter extends over roughly the area of a football field, although only a small fraction of this is composed of modules habitable by humans. The station is so large that it could not be launched all at once — it continues to be built piecemeal. To function, the ISS needs huge trusses, some over 15 meters long and with masses over 10,000 kilograms, to keep it rigid and to route electricity and liquid coolants. Pictured above, the immense space station was photographed from the now-retired space shuttle Atlantis after a week-long stay in 2010. Across the image top hangs part of a bright blue Earth, in stark contrast to the darkness of interstellar space across the bottom.

國際空間站（International Space Station，簡稱ISS）係人類喺太空中建造嘅最大物件。佢個周長大約有美式足球場咁大，雖然只有一小部分係可以容納人類居住嘅模塊。國際空間站咁大，無法一次過發射，至今仍然係逐步建造中。為咗保持穩定，ISS需要大量長達15米以上、重量超過10,000公斤嘅桁架，嚟提供剛性支持，以及傳輸電力同液體冷卻劑。上面圖片係由已退役嘅航天飛機亞特蘭提斯（Atlantis）喺2010年進行為期一週嘅任務中拍攝到嘅壯觀畫面。圖像上方懸掛著一部分明亮嘅藍色地球，與底部無邊際嘅星際空間形成鮮明對比。
