Summary

Description Marius hills pit.png	English: Photograph of a ‘hole’ in the Moon’s surface in the Marius Hills area, Oceanus Procellarum, taken by the Lunar Reconnaissance Orbiter probe (LRO). The right image renders a magnification of the area which is enclosed in the white box in the left image. In the left image the situation of the ‘hole’ within a shallow, sinuous rille structure (rima) is well recognizable. Because rilles are thought to represent fossil lava streams, the ‘hole’ is interpreted as a skylight of a lava tube (cf. Haruyama et al., 2009 ^[1] ). The Marius Hill hole is the first such feature ever spotted on Moon. The scale bar is according to the image being about 900 pixels wide with a pixel covering about 0.5×0.5 m of the Moon’s surface. Deutsch: Foto eines ‚Lochs‘ in der Oberfläche des Mondes in der Marius-Hills-Region, Oceanus Procellarum, aufgenommen von der Lunar-Reconnaissance-Orbiter-Sonde (LRO). Das rechte Bild ist eine Vergrößerung der im linken Bild weiß eingekästelten Region. Im linken Bild ist die Lage des ‚Lochs‘ in einer flachen, gewundenen Mondrille (Rima) gut erkennbar. Weil Mondrillen als fossile Lavaflüsse gelten, wird das ‚Loch‘ als sogenanntes Skylight, die partiell eingestürzte Decke einer Lavaröhre, interpretiert (vgl. Haruyama et al., 2009 ^[1] ). Das ‚Loch‘ in den Marius Hills ist die erste derartige Struktur, die je auf dem Mond entdeckt wurde. Der Maßstabsbalken richtet sich danach, dass das Bild rund 900 Pixel breit ist, wobei ein Pixel etwa 0,5×0,5 m Mondoberfläche abdeckt. ↑ ^a ^b Junichi Haruyama, Kazuyuki Hioki, Motomaro Shirao, et al.
