In April 2026, four astronauts aboard NASA’s Orion spacecraft launched on the Artemis II mission—the first crewed voyage to the Moon since Apollo 17 in 1972. An estimated 25 million people watched the launch live on NASA+, YouTube, and Prime Video, and days later, millions more tuned in to see something no one had ever witnessed: 4K video of astronauts rounding the Moon, transmitted to Earth by laser.
