You also have to care of excessive heat or else dire consequences may result. Usually, heat is generated during reentry when you hit the dense atmosphere at insane orbital speeds of multiple times the speed of sound. The air being pushed out of the way is superheated and transfers some of its heat to the payload. Very small and sturdy satellites can be risked to survive reentry a bit warmed up if they follow a shallow enough reentry trajectory, but heavier payloads (usually manned pods) will require a dedicated part such as a heat shield. A heat shield is composed of ablative material, that gradually melts away during reentry, absorbing a lot of heat in the process. It should be placed right below the payload that is to return to Kerbin and has to have a sufficient diameter to cover the payload fully. It also is directional, so you have to ensure to hit the atmosphere with the heat shield facing forward. If your payload tumbles just slightly during reentry, a non-protected area could face the heated atmosphere and suffer explosion from overheating.

The heat shield is fairly heavy. With experience, you can reduce its weight by reducing the thickness (right-click the part and reduce the amount of ablator), shaving off some more valuable kilograms. It also has an integrated decoupler, meant to be triggered after leaving the dense atmosphere, to reduce the weight the parachute has to slow down.
