Examples

Aerobraking converts the spacecraft's kinetic energy into heat, so it requires a heatshield to prevent the craft from burning up. Source: Internet

As a result, aerobraking is only helpful in cases where the fuel needed to transport the heatshield to the planet is less than the fuel that would be required to brake an unshielded craft by firing its engines. Source: Internet

The Dragon's heatshield characteristics could allow for a safe descent if landing rockets of sufficient power were made available. Source: Internet
