The toilet on the space shuttle was known as the Waste Collection System (WCS) and collected human waste through air flow and the suction it created. Liquid waste was vented to space but solid waste was moved to a cylindrical container below deck and exposed to vacuum to dry it. Air used in these processes is filtered ...

When a space shuttle is mated to a shuttle carrier aircraft (SCA) for transport between space centers, a tail cone is installed over its main engines. This reduces both drag and turbulence created by the piggy-backing spacecraft while also protecting the engines. Discovery's final tail cone was installed in the Orbiter...

The airlock connects the mid-deck of the space shuttle with the cargo bay and the International Space Station (ISS). It is also the preparation area for extra-vehicular activities (EVA), otherwise known as spacewalks. During launch and reentry, the cylindrical airlock is used to store the bulky and heavy space suits us...
