Space+Shuttle+thermal+protection+system+(TPS)

A **space shuttle** is the world's only **reusable spacecraft**. Saying reusable, you cannot reuse it as you can reuse airplanes. These space shuttles need thorough examinations after each flight. Something that helps the reuse of the space shuttle, is __**Thermal Protection System (TPS).**__ This protects the space shuttle orbiter and the people working inside it. The shuttle needs TPS because the aluminum structure of the spacecraft cannot withstand certain temperatures in space, so the TPS is needed to insulate.
