Astronauts can get motion sick while splashing back down to Earth – virtual reality headsets could help them stay sharp

Astronauts experience motion sickness during re-entry to Earth due to a conflict between their brain's expectations of gravity and the absence of it in space. This phenomenon, known as space motion sickness, can impair their performance. Researchers suggest that virtual reality headsets may provide a solution by helping astronauts acclimate to the gravitational changes, potentially enhancing their focus and effectiveness during critical phases of their return. This development is significant as it addresses a common challenge faced by astronauts, ensuring their safety and operational efficiency.
