- The typical bowl/cone-shape of crater Richards is noticeable on Apollo 16's orbital ITEK-panoramic frame AS16-P-4208. In this frame, Richards was captured on the right half of it.
- A wonderful orbital color-Hasselblad photograph of Richards (and part of Catena Mendeleev) is Apollo 16's AS16-118-18977.
- Apollo 10's orbital color-Hasselblad photograph AS10-35-5196 of the not-indexed magazine 35/U shows both Richards and Catena Mendeleev under high sun.
- Almost the same view as the one depicted in the above mentioned photograph (AS10-35-5196) is the B-and-W frame AS10-33-4914 (Richards and Catena Mendeleev, looking north-northeastward).

Theodore William Richards was an American chemist; Nobel laureate. About half of his original work concerned atomic weights, starting in 1886 with work on oxygen and copper. He invented the nephelometer and by 1912 he had redetermined, with the highest accuracy, the atomic weights of over thirty important chemical elements and in later years he was to play his part, by his work on the determination of the atomic weight of isotopes, in the modern concept of the atom.
