Artemis Crew: 40 Minutes Without Contact as the Moon Blocks Signals

As the Artemis crew travels toward the Moon, there is a planned communication gap. When the spacecraft moves behind the Moon, Earth can no longer “see” it, and radio links are interrupted. The BBC explains that, for roughly 40 minutes, the astronauts will experience a quiet, isolated stretch because signals cannot travel through the Moon. During this time, they will be unable to exchange messages with mission control on Earth. The pause is not a malfunction; it is a predictable effect of the Moon’s position. Once the spacecraft emerges on the other side, the line of sight returns and communication begins again. At that point, normal monitoring, guidance, and updates can resume. This brief loss of contact shows how space missions must account for simple geometry, even when everything else is working as planned.
