166. [Apollo 8] THE FIRST PHOTOGRAPH ABOVE THE LUNAR TERMINATOR TAKEN BY HUMANS William Anders, December 21-27, 1968, orbit 1 Printed 1968. Vintage gelatin silver print on fibre-based paper [NASA image AS8-13-2230]. Numbered "NASA AS8-13-2230" in black in the top margin (issued by NASA Manned Spacecraft Centre, Houston, Texas). 20.3 x 25.4 cm. (8 x 10 in.) Historical context This extremely rare photograph, taken during the first revolution of the Apollo 8 spacecraft around the Moon, captures for the first time the boundary between night and day on the lunar surface as seen by humans from lunar orbit. Shot with the Hasselblad 500EL equipped with the 250mm telephoto lens and B&W magazine 13/E, the image showcases how the low Sun dramatically enhances the rugged relief of Montes Pyrenaeus, casting long shadows that accentuate the lunar landscape's striking topography. Montes Pyrenaeus is a mountain range beginning at the southwestern rim of the flooded crater Gutenberg, extending southward along the eastern edge of Mare Nectaris. The range spans approximately 164 km in diameter. Coordinates: [5.5° S / 36.5° E].
