Four of Apollo 16's orbital Hasselblad photographs show dim reflected light on Lobachevskiy's shadowed inner slope, revealing a curious low-albedo feature (a dark streak) on the slope.
AS16-120-19274 (the first one of the four shows a little bit of dim reflected light on the shadowed inner slope).
AS16-120-19275 (the second one of the four is slightly overexposed, and the dark feature is discernible on the shadowed inner slope).
AS16-120-19276 (close up of the dark feature).
AS16-120-19277 (overexposed close up of the dark feature).

Additional Information


  • Nikolay Ivanovich Lobachevskiy (December 1, 1793 - Feb. 24, 1856) was a Russian mathematician. His main achievement is the development (independently from János Bolyai) of non-Euclidean geometry. Another of Lobachevskiy's achievements was developing a method for the approximation of the roots of algebraic equations. In addition to teaching mathematics and physics at Kazan University, he also taught astronomy.
  • Discovered in Lunik 3 imaging of farside and named in Atlas of the Far Side of the Moon and approved by the IAU in 1961 (Whitaker, p 232).
