About 80 seconds just after moving into the environment, the spacecraft experiences peak temperatures, with the warmth protect on the bottom of the capsule reaching 2,370 levels Fahrenheit. Inside of the capsule, it is a lot considerably less toasty — about room temperature. As the air will become denser, the spacecraft continues to gradual.
Compact thrusters on the top rated of the capsule hearth to tweak the angle and route of its descent and continue to keep it on program toward its landing internet site.
At an altitude of about seven miles, four minutes right after entry into the ambiance, the capsule is touring at a velocity less than 1,000 miles for every hour. It then deploys a huge parachute, much more than 70 feet in diameter.
The spacecraft now drops the heat protect, allowing for cameras and other devices to take note of the terrain below to ascertain its position.
Even with the enormous parachute, the spacecraft is nevertheless slipping at about 200 miles per hour.
The next very important stage is referred to as the sky crane maneuver. The major of the capsule, referred to as the backshell, is enable go and is carried away by the parachute. There are two parts of the spacecraft left. The top rated is the descent stage — in essence a rocket-powered jetpack carrying the rover beneath it. The engines of the descent phase hearth, initial steering to stay clear of a collision with the backshell and the parachute. Then the engines slow the descent to fewer than two miles for each hour.
