Crying in space is a little different from crying on Earth. Without gravity, tears don’t fall down your cheeks. Instead, they form small floating blobs of water right in your eyes. Astronauts say it can feel like your eyes are filling up with water, because the tears tend to stick to your skin.
If you cry a lot, the blobs can grow and float away, drifting inside the spacecraft until
the air system filters them out. This is because in microgravity, liquids cling to surfaces due to surface tension. So instead of dripping down, your tears just stay put.
It’s a strange reminder of how even something as simple as crying changes in space. At Vero Q&A, we love exploring these everyday questions with a cosmic twist. The next time you look up at the stars, you might wonder how many astronauts have experienced floating tears far from home.
