５日間のミッションを終えて大気圏に突入したクルードラゴンは、最大１９００度の高熱にさらされながら時速２万７０００キロの速度で下降した
After completing its five-day mission and entering the atmosphere, Crew Dragon descended at a speed of 27,000 kilometers per hour while being exposed to high temperatures of up to 1,900 degrees Celsius.

徐々に減速した宇宙船は、パラシュートを展開し、さらに速度を落として着水
The spacecraft gradually decelerated, deployed its parachute, further reduced its speed, and landed on the water.
