NASA's Artemis II mission launches April 1, with live coverage beginning at 12:50 p.m. Eastern and liftoff targeted for 6:24 p.m. The space agency directs viewers to its NASA+ streaming service as the primary broadcast path, with YouTube serving as a backup option.

NASA built its distribution around its own streaming stack, adding YouTube and other platforms as secondary options. This approach makes clear which feeds are most likely to hold up during a high-demand event. The NASA app provides the most reliable experience on iPhone, iPad, Mac, and Apple TV, offering direct access to live streams and notifications for coverage changes.

For Apple TV users, running the NASA app natively eliminates AirPlay-related issues like dropped connections and battery drain. Safari serves as a universal fallback, accessing all official streams without apps. The practical takeaway is simple -- open NASA+ and keep YouTube ready as a backup. Viewers should confirm everything before coverage begins so the only thing left to do is watch the launch.
