- Although not mentioned in the LPI's search list for Delaunay-related Apollo photographs, it (the odd-shaped formation Delaunay) WAS captured on several of Apollo 16's orbital frames! Delaunay is noticeable in A16's Fairchild-mapping/metric magazines REV 26 and REV 48 (oblique south-looking photographs), such as frame AS16-M-0709, in which Delaunay's location is very near the central part of the curved horizon.

Nomenclature
Charles-Eugène Delaunay (April 9, 1816 – August 5, 1872) was a French astronomer and mathematician. He worked on the mechanics of the Moon as a special case of the three-body problem. His infinite series expression for finding the position of the Moon converged too slowly to be of practical use but was a catalyst in the development of functional analysis.

Lieutenant-Colonel Delaunay?
- A certain Lieutenant-Colonel Delaunay is mentioned on page 548 of the book Mysterious Universe, a handbook of astronomical anomalies (W.R.Corliss, The Sourcebook Project, 1979), more precisely in the article A New Law of Satellite Distances (J.B.Penniston, Science, 1930). Was this Lieutenant-Colonel Delaunay in some way related to Charles-Eugene Delaunay? - DannyCaes DannyCaes Mar 7, 2015
