The Artemis II mission will experience a communications blackout as the spacecraft travels behind the Moon, creating a 40-minute window where astronauts lose their connection to mission control in Houston. The signal disruption will occur at approximately 23:47 BST on Monday as radio and laser communications become blocked by the Moon itself. During this period, the four crew members will be isolated in the darkness of space, though mission controllers anticipate they will use the time for lunar observation, including imaging and geological study.
Artemis pilot Victor Glover has stated that he views the blackout as an opportunity for reflection, encouraging people on Earth to send positive thoughts during the period of silence. The experience echoes historical precedent from the Apollo program, particularly Apollo 11 astronaut Michael Collins, who experienced a 48-minute communications loss while orbiting the Moon in 1969. Collins later described the experience as peaceful and tranquil, offering respite from constant mission control communications, though he did not report feelings of fear or loneliness.
The communications blackout will present challenges for ground teams managing the mission. The Goonhilly Earth Station in Cornwall has been tracking the Orion capsule throughout its journey, and station officials acknowledge they will experience tension during the signal loss before celebrating the crew’s safe reemergence. However, space agencies recognize that such blackouts are unsustainable for future lunar operations. Programs including the European Space Agency’s Moonlight initiative are planning to deploy satellite networks around the Moon to provide continuous 24-hour communications coverage, essential infrastructure for establishing permanent lunar bases and conducting sustained exploration activities.
