[漢羅] 月球南極 ê 烏影
這張月球表面 ê 相片敢是 tī 顯微鏡下底翕 ê? 毋是呢! 這是用闊幅 kha-mé-lah 翕 ê 多重光照圖。 為著欲產生這張圖,月球探測軌道太空船 tī 6 个月球日(地球 ê 6 個月)ê 時間內底,khêng 1700 張影像,以 月球南極 為中心,kā 無仝角度 ê 相片重複疊去-lih。 落尾 這張圖,就是重重疊疊 ê 結果。 表面每一點,其實是去予 太陽 照著 ê 時間比例。 Tī 光照圖中央附近,有一个直徑 19 公里 ê Shackleton 隕石坑 底,伊完全攏 tī 烏影內底。 月球南極 to̍h tī 時鐘 9 點方向 ê 隕石坑 ê 邊仔。 月球南北極 ê 隕石坑底會永遠 tī 烏影 內底,毋閣山頂會 一直去予太陽光 照著。 這張圖 tùi 未來欲起 ê 基地 來講實在是真好用。 去予烏影閘暗去 ê 隕石坑 底,會當提來做 保存水冰 ê 水庫。 照會著 太陽光 ê 山頂,會當提來做儉太陽能 ê 好所在。

[English] Shadows at the Moon's South Pole
Was this image of the Moon's surface taken with a microscope? No -- it's a multi-temporal illumination map made with a wide-angle camera. To create it, the Lunar Reconnaissance Orbiter spacecraft collected 1,700 images over a period of 6 lunar days (6 Earth months), repeatedly covering an area centered on the Moon's south pole from different angles. The resulting images were stacked to produce the featured map -- representing the percentage of time each spot on the surface was illuminated by the Sun. Remaining convincingly in shadow, the floor of the 19-kilometer diameter Shackleton crater is seen near the map's center. The lunar south pole itself is at about 9 o'clock on the crater's rim. Crater floors near the lunar south and north poles can remain in permanent shadow, while mountain tops can remain in nearly continuous sunlight. Useful for future outposts, the shadowed crater floors could offer reservoirs of water-ice, while the sunlit mountain tops offer good locations to collect solar power.
