Entry, descent, and landing systems (EDLS) should guarantee the safe delivery of either manned or unmanned payloads to the surface of a planet or a moon, with a certain specified terminal state. This could relate to the soft landing of a rover on Mars, astronauts on the Moon, or a sample-return mission to Earth. They all have in common that the payload should be “operational” after the landing in the broadest sense of the word: the rover should be able to begin its mission, the astronauts should not be injured in any way, and the samples should not be contaminated, because of a too hard landing. This means that the thermo-mechanical load occurring during the complete mission towards the surface should be well below the specified maximum level. For the EDLS this usually means that the final (or impact) velocity should be below a certain value. However, we should distinguish between the unpowered and unaided flight of entry capsules and winged entry vehicles, and systems that are assisted by sub-systems that provide extra deceleration in addition to that induced by the vehicle itself.
