Millions of people across the world followed every key moment, from the rocket lifting off to the crew flying around the Moon and finally returning safely to Earth. The mission shattered several of NASA’s previous digital records, attracting huge audiences on livestreams, websites, social media, and even popular streaming platforms like Netflix and Amazon Prime Video. Record-breaking livestreams throughout the mission NASA’s live coverage of Artemis II attracted an unprecedented number of viewers across its streaming platforms. The launch broadcast alone reached a peak audience of more than 3.66 million concurrent viewers, making it NASA’s most-watched livestream ever. This record was even higher after adding viewers from X and Twitch. The event outperformed previous milestone broadcasts, including the Artemis I launch and the James Webb Space Telescope launch. The launch coverage generated 23.9 million total views, with 16.6 million people watching live. Moon flyby attracted another massive audience Public interest remained high as the Orion spacecraft reached the Moon.

X and Twitch also attracted hundreds of thousands of additional viewers.

Because re-entry through Earth’s atmosphere is considered one of the riskiest parts of any space mission, millions of viewers tuned in to watch the crew’s safe return. NASA’s splashdown broadcast attracted 3.84 million peak viewers, around 4.8% higher than the launch audience. The return coverage generated 29.5 million total views, including approximately 24.1 million live views, showing that public interest stayed strong until the mission’s final moments.
