The 40 Minutes When the Artemis Crew Loses Contact with the Earth

As the Artemis astronauts venture deeper into space, they become the farthest human presence from Earth. Yet, until a specific moment, their mission remains tethered to the team on the ground. The ongoing dialogue with Houston, Texas, has offered them a steady connection to home. But that bond is set to vanish. When the spacecraft glides behind the Moon at approximately 23:47 BST on Monday, the lunar body will block all radio and laser transmissions, severing the link for roughly 40 minutes. During this period, the crew will experience complete isolation, each with their own reflections in the vastness of space.

The silence will be profound, a moment of solitude that stretches across the void. Victor Glover, one of the crew members, has expressed the importance of this interval. “When we’re behind the Moon, out of contact with everybody, let’s take that as an opportunity,” he told BBC News prior to the mission. “Let’s pray, hope, send your good thoughts and feelings that we get back in contact with the crew.”

A Historical Echo: Apollo’s Silent Interval

Decades ago, Apollo astronauts faced similar disconnections. The experience was particularly poignant for Michael Collins during the Apollo 11 mission. While Neil Armstrong and Buzz Aldrin made history on the Moon’s surface, Collins orbited alone in the command module. As his spacecraft passed the far side, communication with both the lunar pair and mission control disappeared for 48 minutes. In his 1974 memoir Carrying the Fire, Collins described the feeling of “truly alone” and “isolated from any known life,” though he noted no sense of fear or loneliness.

“For a sustainable presence on the Moon, you need the full comms – you need the full 24 hours a day, even on the far side, because the far side will want to be explored as well,” said Matt Cosby, Goonhilly’s chief technology officer.

While the Artemis crew will have their 40-minute blackout, the event is a test for those on Earth responsible for maintaining the link. At Goonhilly Earth Station in Cornwall, a massive antenna tracks the Orion capsule, relaying its position to NASA headquarters. Cosby, reflecting on the moment, added: “We’re going to get slightly nervous as it goes behind the Moon, and then we’ll be very excited when we see it again, because we know that they’re all safe.”

Looking Ahead: A Connected Moon

Despite the temporary silence, the hope is that such communication gaps will eventually be eliminated. Programs like the European Space Agency’s Moonlight aim to deploy a satellite network around the Moon, ensuring uninterrupted coverage for future missions. This initiative is critical as global space agencies plan to establish a permanent lunar base and expand exploration efforts.

For the Artemis astronauts, the blackout period will serve a dual purpose. It will grant them focused time for lunar observation, including imaging, geological study, and simply appreciating the Moon’s majesty. When the signal returns, the world will share in the relief, as the crew unveils their extraordinary views of Earth and space, marking a historic milestone in human exploration.
