The Short Version
No credible evidence supports the claim that Artemis II was staged on a green screen. The viral images and videos cited as "proof" of staging were traced to AI-generated fabrications bearing Google SynthID watermarks, while broadcast visual anomalies were explained as standard overlay and recording artifacts. Independent verification from NASA, the Canadian Space Agency, ground-station telemetry, and multiple international fact-checkers all confirm the mission was a genuine crewed lunar flyby.
