ALT The historic first photograph of Earth taken from the vicinity of the Moon, captured by NASA’s Lunar Orbiter 1 on Aug. 23, 1966. In the black-and-white image, a partially illuminated Earth appears above the lunar horizon against the darkness of space. The Moon’s rugged, cratered surface fills the lower half of the frame, with faint vertical scan lines visible across the image. Credit: NASA

ALT The iconic “Earthrise” photograph captured by astronaut Bill Anders during the Apollo 8 mission on Dec. 24, 1968. The Moon’s gray, textured surface stretches across the bottom of the image, while Earth appears small in the distance above the lunar horizon, surrounded by black space. Blue oceans, white cloud patterns and land are visible on the planet. Anders took the photograph from the Apollo 8 spacecraft as the crew traveled in lunar orbit. Credit: NASA

ALT The “Earthset” image captured through a window of the Orion spacecraft during the Artemis II crew’s flyby of the Moon on April 6, 2026. A partially illuminated blue-and-white Earth appears behind the Moon’s cratered horizon against the blackness of space. Swirling white clouds are visible across Earth’s sunlit side, while much of the planet is in darkness. In the foreground, the rugged lunar surface stretches across the lower half of the image.

ALT Inside a large, dark chamber, a long white cylindrical structure stretches horizontally across the center of the image, supported at both ends. Two technicians in white garments stand on either side. Bright lights shine from the back of the chamber, and a gold-colored, foil-covered component sits on a platform below. The image was taken during vertical solar array technology prototype testing in Chamber A at NASA’s Johnson Space Center in July 2024. Credit: NASA/James Blair
