Astronauts' outer space poo area. Buzz Aldrin became the first man to poo on the moon in 1969. He collected his waste in a bag, but because of zero gravity, the contents would often escape during the disposal process and fly around the shuttle. To curb this issue, astronauts ate very little fiber to prevent them from pooing very often. Modern astronaut toilets work like a vacuum cleaner. In order to use the toilet the astronauts must strap themselves to the toilet seat and then turn on a powerful fan. A suction hole then slides open and the poo is sucked away to be stored, and then disposed. from http://www.vincecorvelli.com/poo.htm.
