Caption: This is an image of an artificial moon rock sample, measuring about half a millimeter across, made with an electron microprobe at ambient temperature after the experiment with X-rays. The fragmentation of the sample occurred when it was extracted from the small diamond cylinder in which it had been melted under high pressure and temperature.
