月球近側
Lunar Nearside

發表日期:2025-07-20
月球勘測軌道飛行器的廣角相機拍攝了大約 1300 張影像,用來合成這幅壯觀的影像,其中有一張我們熟悉的面孔--月球近側。但為什麼會有月球近面呢?月球以自己的軸為中心自轉,並以同樣的速度繞地球執行,大約每 28 天一次。在這種配置下,同步自轉始終保持一邊(即近邊)朝向地球。因此,在全解析度馬賽克中,光滑、黝黑的月壤(實際上是熔岩氾濫的撞擊盆地)和崎嶇不平的高地都非常詳細,為地球上的觀天者所熟知。要找到你最喜歡的母巖或大隕石坑,只需點選這個連結或將游標滑到圖片上即可。用於構建馬賽克的 LRO 影像是在 2010 年 12 月的兩週時間內拍攝的。
原文:About 1,300 images from the Lunar Reconnaissance Orbiter spacecraft's wide angle camera were used to compose this spectacular view of a familiar face - the lunar nearside. But why is there a lunar nearside? The Moon rotates on its axis and orbits the Earth at the same rate, about once every 28 days. Tidally locked in this configuration, the synchronous rotation always keeps one side, the nearside, facing Earth. As a result, featured in remarkable detail in the full resolution mosaic, the smooth, dark, lunar maria (actually lava-flooded impact basins), and rugged highlands, are well-known to earthbound skygazers. To find your favorite mare or large crater, just follow this link or slide your cursor over the picture. The LRO images used to construct the mosaic were recorded over a two week period in December 2010.
