View of Apollo 16 lunar sample no. 68815

A closeup view or "mug shot" of Apollo 16 lunar sample no. 68815, a dislodged fragment from a parent boulder roughly four feet high and five feet long encountered at Station 8. The crew tried in vain to overturn the parent boulder. A fillet-soil sample was taken close to the boulder, allowing for study of the type and rate of erosion acting on lunar rocks. The fragment itself is very hard, has many veticles and a variety of inclusions. In addition, numerous metallic particles were observed in the black matrix.
