When four astronauts board the Orion capsule for Nasa’s Artemis II mission, the first crewed deep-space journey since Apollo, they won’t just be making history.
Nasa is set to launch Artemis II on April 2, 2026 at 3:54 am IST, marking a major step in humanity’s return to the Moon, sending its crew of four astronauts to the Moon.
On their commute to the Moon and back, the members of the crew will be wearing special wristband monitors that will track their every sleep cycle, stress response, and team interaction.
This is the Archer study, and it could shape how humanity one day gets to Mars.
WHAT IS ARCHeR?
Archer stands for Artemis Research for Crew Health and Readiness. It monitors astronauts’ sleep patterns, stress levels, cognitive performance, and teamwork dynamics using wearable wristbands.
These devices collect real-time physiological and behavioural data, helping researchers understand how isolation, confinement, and the unique environment of deep space affect crewmembers.
The collected data will lay the foundation for Nasa’s space ambitions, and could help inform the planned Mars missions in the future.
During the approximately 10-day mission, Nasa astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen will wear wrist monitors that track movement and sleep, and offer other essential data for Nasa’s Human Research Program.
Data on cognition, behaviour, and team dynamics will additionally be gathered before and after the mission.
WHY ARE WRISTBANDS GOING TO SPACE?
Unlike missions in low Earth orbit, deep-space missions involve longer durations and greater psychological stressors, making this research vital to optimise human performance for future exploration.
Artemis II will be the first time Nasa astronauts go beyond low-Earth orbit since the Apollo era, and the first astronauts heading into space in the Orion vehicle.
This will provide a critical opportunity to refine the understanding of behavioural medicine, teamwork, and sleep risks.
“Artemis missions will be the farthest Nasa astronauts have ventured into space since the Apollo era,” said Suzanne Bell, a Nasa psychologist leading the investigation. “The study will help clarify key mission challenges, how astronauts work as a team and with mission control, and the usability of the new space vehicle system.”
The monitors will enable crew members and flight controllers in mission control to study real-time health and behavioural information for crew safety, and help scientists study how crew members’ sleep and activity patterns affect overall health and performance.
Results from each mission will be used to understand the combined effect of space hazards on well-being and performance, and to develop protocols, interventions, and technologies that will enable humans to survive and thrive for future Moon and Mars missions.
As Artemis II inches closer to launch, the tiny wristband on each astronaut’s arm may become one of the most consequential scientific instruments of the mission.
