Upper frame: Clementine.
Lower frame: LROC; which also shows bright ray crater Joule T near the frame's left margin, with bright crater Wargo on the western part of its rim.
Crater Joule is easy to recognize because of its "hanging bag" Joule L south of it.
- James Prescott Joule, FRS (December 24, 1818 – October 11, 1889) was an English physicist. Joule studied the nature of heat, and discovered its relationship to mechanical work. This led to the theory of conservation of energy, which led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after him. He worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the flow of current through a resistance and the heat dissipated, now called Joule's law.
- The small bowl-shaped high albedo crater on the western part of the rim of raycrater Joule T (west of Joule itself) received the official name Wargo in July 2017.
