This handout picture released on April 7, 2026, by NASA shows crescent Earth setting along the Moon`s limb, as seen from the Orion spacecraft on April 6, 2026. The edge of the visible surface of the Moon is called the “lunar limb.”. The Artemis II astronauts wrapped up their lunar flyby as they continue their journey back to Earth on Tuesday, bringing with them rich celestial observations including little-known lunar craters, a solar eclipse and meteor strikes that scientists hope will open doors.
