Summary

Story summary

A study by Université catholique de Louvain, with 11 International Space Station astronauts, finds grip in microgravity feels heavier.
The astronauts overcompensate grip strength, which could raise risks during space operations.
After returning to Earth, astronauts quickly readapt to gravity but initially struggle with grip force.
Published in the Journal of Neuroscience, the findings show the brain adapts to different gravities, informing future Moon or Mars missions.
