Artemis I: Flight Day 13
Image Credit: NASA, Artemis I

Explanation: On flight day 13 (November 28, 2022) of the Artemis 1 mission, the Orion spacecraft reached its maximum distance from Earth. At over 430,000 kilometres from Earth, its distant retrograde orbit also puts Orion nearly 70,000 kilometres from the Moon. In the same field of view in this video frame from flight day 13, planet and large natural satellite even appear about the same apparent size from the spacecraft's perspective. On flight day 26 (December 11, 2022), the uncrewed spacecraft splashed down on its home world concluding the historic Artemis I mission. The Artemis II mission, carrying 4 astronauts around the moon and back again, will launch no earlier than February 8.
