The atmospheric drag will absorb most of this speed, but it will still move at 300 mph (483 km / h), slowing down at subsonic speed. The latter must be reduced to 32 km / h (20 mph) if the spacecraft and the crew want to avoid being destroyed on impact. This is the job of the parachute system. Similar to the one developed for the Apollo control module, the Orion landing system consists of 11 parachutes covering an area of 3,300 m². These are deployed in sequence using mortars, pyrotechnic bolt cutters and 48 km of Kevlar ropes on the descent of about 10 minutes of the capsule through the Earth's atmosphere. , slowing it down in the Pacific Ocean.
