Piatek sent the stone to Agee, who wasn\u2019t convinced that it was a meteorite at all. It didn\u2019t have the heft of a chondrite, which are typically rich in dense metals. And the scaly skin\u2014the \u201cfusion crust\u201d that forms on the superheated surface of a falling meteorite\u2014seemed so shiny that it might be fake. \u201cI thought someone had taken a desert stone and spray-painted it,\u201d Agee says. Nonplussed, he stuck the rock on a shelf for a few months. Eventually, in the fall of 2011, he took a diamond-tipped rock saw, sliced off one end of the stone\u2014and marveled at what he saw inside. Dark, angular crystals of pyroxene floated alongside white, chunky feldspars. Large, faint pebbles sat next to tiny, dark beads. It was evocative of the lunar breccias Agee recalled from the Apollo days\u2014except that Black Beauty\u2019s spherules were much more diverse.<\/em><\/p>\n

Agee now knew he had a meteorite, but what was it? He chipped off a gram piece and put it under an electron microprobe, which uses an electron beam to excite atoms in the rock\u2019s minerals. The atoms then emit x-rays that reveal the sample\u2019s chemical makeup. It turned out that the rock had an elevated manganese-to-iron ratio\u2014higher than that in Earth rocks and consistent with other martian meteorites. Next, Agee and his colleagues used a laser to extract water molecules trapped within minerals in the meteorite and fed them into a mass spectrometer to calculate the ratio of deuterium, a heavy isotope of hydrogen, to ordinary hydrogen. Every place in solar system has a distinctive ratio. Lo and behold, the copious water in Black Beauty was Mars-like.<\/em><\/p>\n
