Since gravity doesn’t work in space，astronauts need some extra help to get rid of the tears.Feustel chose to rub his eyes against his helmet to wipe the tears away.Another choice is to just wait—“When the tears get big enough they simply break free of the eye and float around，” astronaut Ron Parise told The Atlantic.

　　There are lots of small things—things like crying—that we are so used to on Earth.We usually take them for granted，until they become a problem in a totally different environment，like space.There，astronauts can’t talk to each other directly.They also can’t eat or drink in normal ways.They can’t even burp(打嗝)，because there is no gravity to hold the food down in their stomach.If they do burp，they just end up throwing up(呕吐) everything in their stomach，according to the UK National Space Center.

　　Thus，perhaps it’s only space explorers who can honestly say，“Gravity，you’re the best.”
