They are called bunny suits with knee high booties. Plus the inside crew compartment is vacuumed and wiped with alcohol daily. We remove all waste materials here at KSC or at our California landing facility. The waste is analyzed by Boeing at the Houston operations. The potty waste is removed by Hamilton and Standard at their operations in Houston.
Liquid waste is dumped into the sewer systems.
Hello to John, Patty, Alex and Albert from Ameridioma School in Guadalajara, Mexico. It was nice to see people who were interested in my work from outside my country. I hope you are having fun and learning good stuff. I cannot give you an exact number at this time because they are located in three different areas of the orbiter, forward, midbody and aft. I know there are more than 100 in the forward alone.
