A ParallelView of the Vavilov crater and the surface of the Moon

A close-up view taken by the Artemis II crew Vavilov Crater on the rim of the older and larger Hertzsprung basin on Monday, April 6, 2026. The right portion of the image shows the transition from smooth material within an inner ring of mountains to more rugged terrain around the rim. Vavilov and other craters and their ejecta are accentuated by long shadows at the terminator, the boundary between lunar day and night. The image was captured with a handheld camera at a focal length of 400 mm, as the crew flew around the far side of the Moon. (NASA)
