Well according to the passage crying in space just sticks to you eye and it make a bubble but why? My thought is that gravity makes water floate in space and water will stick to the eye just like a wall with water droplets. But my question is that why does the water bubble get big?

I think this is crazy that they made it to Mars. I learned that they explored for 1 hour and 12 minutes which is really long. How long did it take to get there?

Wow that's really cool, I didn't know that in zero gravity tears can form normally. But i still have one question why do the tears join together and form one, why don't they just fall to the ground like normal.
