The sample is situated just below the sapphire window at bottom. The platform can be leveled relative to sapphire window with a precision of less than 0.001 inches. The platform is powered by optically encoded, piezo driven, non magnetic motors. Scan is visible on computer screen at center.

This crust formed during entry through Earth's atmosphere. This is the same sample as that displayed in Image 1 at the top of this webpage. An outline of the slice, corresponding to the edge of the slice in the photograph at the right, is drawn around the sample. Scale bars are 2 mm.
