Space exploration presents unique challenges for human physiology and cognition, especially in the domain of spatial orientation and navigation. In microgravity environments, such as the International Space Station (ISS), astronauts face a radically different spatial experience compared to Earth’s gravity-based orientation. In this article, we explore the neurocognitive mechanisms underlying spatial orientation and navigation in astronauts, highlighting how their brains adapt to the demands of space travel, the impact of microgravity on sensory processing, and the cognitive strategies used to maintain navigational abilities in unfamiliar and shifting environments. Spatial orientation refers to the ability to perceive and process information about the position of the body and objects in space. Navigation, on the other hand, is the ability to move through and understand one's position within a larger environment. These abilities are essential for survival, particularly in environments like space, where the lack of gravity and the unfamiliarity of the surroundings make traditional cues and reference points less reliable. On Earth, spatial orientation is primarily guided by a combination of sensory inputs, including visual, proprioceptive (sensory feedback from muscles and joints), and vestibular (inner ear) information. These sensory systems work together to provide feedback that helps individuals determine their body’s orientation in space. In microgravity, however, these inputs become altered, and astronauts must adapt their cognitive systems to compensate for the absence of traditional reference points
