This microscopic view of a thin slice - less than 1/1,000th of an inch (30 micrometers) thick - of lunar meteorite MIL 05035 reveals the mineral pyroxene (bright mosaicized colors) and maskelynite (dark gray areas), which formed when an intense shock transformed feldspar into glass. MIL 05035's coarse grain size and inclusion of maskelynite are unusual among other lunar specimens.
