A new NASA-funded study has uncovered a critical ingredient for success in future deep-space exploration: the ability of large groups of people to maintain a shared focus despite communication delays. Published in Personnel Psychology, the research identifies “collective attention” as the key mechanism that allows complex teams to coordinate effectively when separated by vast distances, offering new insights for future missions to the Moon, Mars, and beyond.
Why Collective Attention Matters For Deep-Space Exploration
Sending humans to Mars is often discussed as an engineering challenge involving rockets, habitats, life-support systems, and advanced spacecraft. Yet the human side of the equation may prove just as important. Future astronauts will operate millions of miles from Earth, where communication delays could stretch from several minutes to nearly an hour depending on planetary positions. During emergencies, equipment failures, or scientific operations, teams will no longer be able to rely on instant conversations.
Researchers from Michigan State University set out to understand how these delays affect coordination between astronauts and Mission Control. Their work focused on large interconnected networks of people rather than individual teams alone. Dorothy R. Carter, associate professor of management at Michigan State University, explained the broader challenge facing future exploration programs. “NASA realized the collaboration that a long-duration mission, like sending a team of humans to Mars, goes far beyond just the members of the crew on the spacecraft. The astronauts have to continue to collaborate with many people on Earth,” Carter said. “To do that effectively requires a large, collaborative—or ‘multiteam’—system.”
The study suggests that successful missions will depend not only on technology but also on the ability of numerous specialized groups to remain aligned around the same priorities. Scientists, engineers, flight directors, medical experts, and astronauts must continuously interpret information, assess risks, and make decisions together. When communication becomes delayed, maintaining that shared understanding becomes significantly more difficult, creating a challenge that traditional teamwork models have struggled to explain.
Simulating The Communication Challenges Of A Mission To Mars
To investigate the problem, researchers conducted experiments using NASA’s Human Exploration Research Analog, or HERA, at the Johnson Space Center in Houston. The facility serves as a realistic environment where volunteers live and work under conditions designed to mimic aspects of space missions. Participants inside the habitat acted as astronauts while volunteers at Michigan State University performed the role of Mission Control.
The research team introduced varying levels of communication delay into the simulations, creating conditions similar to those expected during deep-space travel. They then analyzed interactions between the groups and fed the resulting data into computational models to examine how larger multiteam systems might behave under similar circumstances.
What emerged from the analysis was a consistent pattern. The most significant factor influencing performance was not simply the amount of information exchanged or the speed of communication. Instead, it was whether different groups were able to focus their attention on the same issue at the same time. Researchers defined this phenomenon as collective attention, a shared alignment of priorities across multiple teams working toward a common goal.
The findings, published in Personnel Psychology, represent one of the first efforts to place collective attention at the center of the relationship between communication delays and team effectiveness. This insight could help reshape how organizations prepare for operations in environments where real-time communication cannot be guaranteed.
The Hidden Cost Of Communication Delays
The consequences of delayed communication extend beyond inconvenience. When messages take minutes to arrive, teams can begin operating with different assumptions, different priorities, and different understandings of unfolding events. Small misunderstandings can gradually grow into larger coordination problems.
According to Carter, the disruption affects a fundamental aspect of teamwork. “Communication delays disrupt collective attention dramatically. It’s just more difficult for us to focus on the same thing at the same time when we can’t communicate with one another in real time,” Carter said.
This challenge becomes particularly significant during high-pressure situations where rapid adaptation is required. In a Mars mission scenario, astronauts may encounter unexpected equipment malfunctions, environmental hazards, or medical issues. At the same time, specialists on Earth may be analyzing incoming data and developing recommendations. If both groups are focused on different aspects of the problem, decision-making can slow down or become fragmented.
Strategies That Can Keep Teams Aligned Across Vast Distances
While the research identified a significant challenge, it also pointed toward practical solutions. Carter and her colleagues found that organizations can take deliberate steps to preserve collective attention even when communication delays cannot be eliminated.
“Based on our research, there are many different interventions that we think could help support collective attention, even during periods of communication delay,” Carter said.
The study emphasizes three broad areas that can strengthen team performance: increasing individual capability, improving communication clarity, and fostering stronger connectivity between team members. These measures help reduce confusion and improve the likelihood that different groups remain focused on the same objectives.
Carter outlined several examples. “Some examples include developing trust between members of Mission Control and the crew in space before the mission takes off, training on how to speak simply and clearly, engaging in structured debriefing processes and communication protocols, and getting a sense of everyone’s strengths and weaknesses to know who is best positioned to take charge in certain scenarios.”
Lessons For The Future Of Human Exploration
As NASA and other space agencies prepare for increasingly ambitious missions beyond low Earth orbit, understanding the human dimensions of exploration is becoming more important. The return to the Moon through Artemis missions and eventual plans for Mars expeditions will place unprecedented demands on coordination between astronauts and ground teams.
The concept of collective attention offers a framework for addressing those demands. By ensuring that distributed groups maintain a shared focus despite separation and communication constraints, future missions may improve both safety and effectiveness.
“Teams should be prepared to think clearly, communicate in simple ways and build strong connections with each other. These steps help everyone stay focused on the same goals, even when communication is broken up or delayed,” Carter said. “These ideas also help us better understand how teams work across time and distance and provide a starting point for helping them succeed in challenging, high-pressure environments.”
The research points to a future where mission success depends as much on human coordination as on engineering excellence. As humanity pushes deeper into the solar system, staying connected may not simply be about transmitting messages, it may be about ensuring that everyone, no matter how far apart they are, is paying attention to the same thing at the same time.
