As a seasoned gamer who has spent countless hours navigating virtual galaxies and surviving alien invasions, I can’t help but feel a strange sense of familiarity when I delve into the world of space missions and their challenges. The parallels between the high-stakes decisions in space travel and those in video games are uncanny – both demand quick thinking, resource management, and a willingness to adapt to ever-changing circumstances.
In space expeditions, astronauts frequently need to act swiftly and independently, as a misstep at a critical juncture could lead to catastrophic outcomes, stranding the team in perilous situations, miles away from their home base. To date, our space missions have primarily been confined to our vicinity. The unfortunate crew of Apollo 13 also benefited from immediate communication with Earth and guidance from ground control during their ordeal.
In their voyages deeper into space towards Mars and beyond, astronauts encounter an additional challenge: extended communication lags. The duration of these delays depends on the positions of Earth and Mars in their orbits, ranging from 4 to 24 minutes in each direction. If an emergency arises on Mars, as it likely will, the crew may not be able to afford a 20-minute pause before acting. Maintaining optimal cognitive function throughout the mission will be vital for the success of long-distance space travel.

It’s common knowledge that spending time in space can have harmful impacts on the human body. Astronauts may encounter issues such as vision problems, muscle atrophy, bone density loss, and even kidney complications. While the brain’s response to space is less clear, it plays a crucial role in mission success and the long-term wellbeing of the crew members.

To bridge that intellectual divide, a recent study published in Frontiers in Physiology evaluated the cognitive abilities of 25 astronauts from NASA before, during, and after their tenure on the International Space Station (ISS). The research revealed shifts in working memory, processing speed, and sustained attention, yet no overall deterioration in cognition across the group.
How being in space changes the way astronauts think
Deep space voyages involve inherent dangers, even under ideal conditions. When complications arise, as they inevitably do, the mental agility of astronauts becomes crucial for overcoming these challenges. This predicament is vividly depicted in the TV series SYFY‘s The Ark, where we follow the crew of the Ark One, humanity’s pioneering interstellar colony ship embarking on a long journey. Despite their comfortable accommodations like sleeping pods and artificial gravity, their mission takes a turn for the worse when the vessel sustains damage and half the crew, including all leadership members, mysteriously disappears into nothingness. The remaining crew must act swiftly to preserve their lives and restore the ship amidst the vast void between stars.
As I sit here back on Earth, gaming away, I can’t help but think about my astronaut counterparts up there, navigating the cosmos. They’re trying to understand the intricacies of human brain function in space, aiming to make future voyages smoother. You see, before they blast off, they take a series of tests – 10 in total. These are taken once before the flight, again during the early phase of their 6-month mission, then near its end, and twice more within 30 days of landing.
During the initial stage of the mission, the tendency to take risks decreased and then increased again later on. However, some other issues lingered into post-flight, failing to return to their usual state even 30 days after landing on Earth. This shows that the effects may vary among astronauts, with some individuals experiencing more impact than others, but there were no overall group differences. Notably, there was no link found between the level of risk-taking and the amount of sleep or reported alertness by the astronauts.
The study isn’t definitive yet whether the minor cognitive issues found are due to space conditions (microgravity, radiation, isolation) or high-stress environments. However, it’s known that space is incredibly stressful, and other studies suggest that stress can affect cognitive abilities. It might not be possible to completely counteract these effects, but this research could help us understand when astronauts’ cognition may be impaired and adjust missions accordingly, taking into account human limitations.
