Not every photograph taken on the Moon was perfectly composed, as this example, taken by Harrison Schmitt, shows.

Rare and had an original mass of 2.81 kg. It is a feldspathic brecciabasalt clasts and glass fragments are also present (Meteorite with prominent white clasts of anorthosite, the dominant rockBulletin database 2019a).Figure 3.Lunar and Martian meteorites. A) Lunar meteorite NWA 11273, composed of a feldspathic breccia. B) Hell Q crater, a very young, 3.4 km diameter crater on the Moon, an event of this size would eject lunar material with sufficient velocity for some to end up on Earth as lunar meteorites (NASA LROC image). C) A Martian meteorite, NWA 8657. Dark areas are shocked plagioclase glass. D) Ceraunius Tholus (left), and Uranius Tholus, two small volcanoes in the Tharsis Ridge region. The caldera of Ceraunius Tholus is approximately 24 km across. NWA 8657 would have been ejected by an impact into a relatively young (150-200 Mya) volcanic province such as this within the last few million years (NASA/MSSS image).45 PREVIEW OCTOBER 2019'
