月球勘测轨道飞行器(Lunar Reconnaissance Orbiter)上的广角相机拍摄了大约1300张图像,这些图像构成了这幅熟悉的月球近面壮观景象。但是为什么月球会靠近月球呢?月球绕地轴旋转,并以同样的速度绕地球公转,大约每28天公转一次。潮汐锁定在这种结构中,同步旋转总是保持一侧,即近侧,面向地球。因此,在这张全分辨率的拼贴图中,光滑、黑暗的月海(实际上是熔岩泛滥的撞击盆地)和崎岖的高地对地球上的天文观测者来说是众所周知的。要找到您最喜欢的母马或大型陨石坑,只需遵循此链接或将光标滑动到图片上。用于构建马赛克的LRO图像是在2010年12月的两周内记录的。

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.
