Atmospheric entry occurs when a spacecraft enters the atmosphere of a planet, such as HOM; for the purpose of a splash-down landing in a body of water or other liquid. Successful entry can only be performed with the following spacecraft:
- Atmospheric Probe (doesn't come with a parachute, so it will explode on landing in the sea of HOM, or chemical in other planets.)
- Crew Capsule
- Crew Capsule Dockable
- Draco Cargo Capsule
- Draco Crew Capsule
- Gemini Capsule
- LOK Crew Capsule
- Orion Crew Capsule
During atmospheric entry, the capsule will experience turbulence, caused by the capsule descending into thicker atmosphere at extreme velocity. This causes it to pitch upside down, which turns the protective heat shield away from the passing airflow. If the capsule's heat shield is turned to one side for too long, the capsule will overheat and explode.
- In actual atmospheric entry spacecraft, the capsule's mass is situated so its center of gravity is very low in the capsule; which assists in keeping the heat shield facing down so it will protect the capsule. Typically, the bottoms of space capsules are curved, which also aids in keeping the capsule oriented upright during the descent of atmospheric entry.
