WTN- Only happy people allowed in space as no scientific scope of crying in space. Because there is no gravity in space but zero gravity atmosphere does not have an impact on tears forming. But your tears get affected by zero gravity as they don’t fall from your eyes like earth.

ISS commander Chris Hadfield demonstrates what happens to tears if they start 'falling' in Space. Have a look:
