地球上空的天空實驗室
Skylab Over Earth
影像提供: Skylab, NASA
Explanation:
Skylab was an orbiting laboratory launched by a in May 1973. Skylab, pictured above, was visited three times by NASA astronauts who sometimes stayed as long as two and a half months. Many scientific tests were performed on Skylab, including astronomical observations in ultraviolet and X-ray light. Some of these observations yielded valuable information about Comet Kohoutek, our Sun and about the mysterious X-ray background - radiation that comes from all over the sky. Skylab fell back to earth on 11 July 1979.
說明:
天空實驗室 (Skylab)是一座在地球軌道上的實驗室,它是在1973年由土星五號火箭推送昇空。 美國太空總署的太空人曾三次造訪上面影像中的天空實驗室,最長停留二個半月之久。 曾經在天空實驗室進行的實驗,包括在紫外波段和X射線波段進行天文觀測,得到了許多有關科胡鐵克彗星 (Comet Kohoutek)、太陽和來自天空各處的神祕X射線背景輻射之重要資料。 1979年7月11日,天空實驗室在墜回地球時焚毀。
