Video Of The Week - Why Astronauts Never Shed Tears

By

CCSS NAS-4

Though it is common knowledge that lack of gravity makes life in space a tad different from that on earth, very few of us ever think about how different. There is of course the fact that astronauts are always suspended and floating around, but what about beyond that? Something as basic as shedding a tear or two of joy or sorrow?

Turns out that the scientists cannot do that at all! That's because while the tears can form normally, the zero gravity environment prevents them from falling. Instead, all that ends up happening is that multiple tears turn into blobs of water that sit right next to eye or if they get really big, move around the face but never, down to the ground!

Sounds unbelievable? Then watch Canadian astronaut and the current commander of the International Space Station Chris Hadfield, demonstrate it for you.

            Omg I wander what the tears feel like. Are they watery and they just don't fall because of the no gravity or are they jelloy because the tears look like a big glob of goo

                      There is no gravity so it doesn't fall

                        well there is gravity the gravity on the international space station is as strong as it is here but they are orbiting so they just float around
