Artemis II sent humans farther from Earth than ever before and offered an unprecedented look at the moon’s far side. But this historic mission wasn’t just about returning to the moon. Aboard Orion, astronauts put next-generation communications, navigation, spacecraft controls, and life-support systems to the ultimate test. And what we learn by pushing technology to its limits in space could ultimately change how we live, work, and innovate on Earth. NASA leaders take us inside the breakthroughs, high-stakes engineering challenges, and bold ideas behind the Artemis II mission and reveal how it is laying the groundwork for a lasting human presence on the moon, future missions to Mars, and what comes next.
