What happened

How Artemis II livestreamed hi-def videos and images from the moon to Earth Gaby Clark Scientific Editor Robert Egan Associate Editor This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its…

Why it matters

The livestreaming of high-definition video and high-resolution photos of the moon and Earth was made possible through the Orion Artemis II Optical Communications System (O2O).

Common ground

Developed by MIT Lincoln Laboratory in collaboration with NASA Goddard Space Flight Center, the onboard O2O payload was the space end of a high-speed laser communications (lasercom) link.

Perspective signals

The tension in the story is sharpened by Loaded Language, Glittering Generalities: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
