In zero gravity, movement isn’t as simple as taking a step forward. Without gravity to anchor you, the only way to move is by pushing off something or using specialized tools. If an astronaut ends up floating in the middle of a spacecraft or untethered in space, they can’t move because there’s nothing to push against! It’s one of the challenges of living and working in microgravity, which is why astronauts train extensively and use safety measures like tethers or jetpacks to stay mobile. Space m
