The Apollo program's orbital photographs of the bright crater Saha E (east-northeast of Saha itself)
AS16-113-18285 and the following four photographs in Apollo 16's Magazine 113-A show the distant CSM Casper (above the curved horizon, at left), and the rising Earth. Near the lower left corner is the bright crater Saha E, and adjacent to it (rightward) Saha D. North is to the right. Looking westward.
AS10-28-4026 shows a vertical look at the northern part of the bright crater Saha E.
AS10-28-4028 is one of Apollo 10's mystery photographs because there are no coordinates mentioned. The depicted area is part of Saha W, immediately northwest of Saha itself (discovered by D.Caes).
AS10-30-4371 shows an oblique look at both Saha E and D.
AS11-44-6622, made after the first manned lunar landing (Apollo 11), shows the approaching Ascent Stage of LM Eagle over the same region which was captured in AS16-113-18285 (see above).
AS11-42-6281 is a wonderful orbital black-and-white close up of Saha E. Note its partial "double rim"!

Nomenclature
- Named for Megh Nad Saha (October 6, 1893 – February 16, 1956), a Bengali Indian astrophysicist. He invented an instrument to measure the weight and pressure of solar rays. He produced the famous equation which he called 'equation of the reaction - isobar for ionization' which later became known as Saha's "Thermo-Ionization Equation", or the Saha Equation. According to the Scientific American, this equation became the foundation for the field of astrophysics.
- Saha was among the long list of farside names approved by the IAU in 1970 and published in [/Menzel%2C%201971 Menzel, 1971].
- In the planning for Apollo 8, the first manned circumlunar mission (1968), this crater (which did not then have an official name) was referred to informally as "Charlesworth" (see Phil Stooke's LPOD).
