Glass coatings are useful for a variety of applications, including heat shielding and the protection of high-performance alloys from corrosion and oxidation when exposed to high temperatures.
you re traveling at 17,500 miles an hour when you re in orbit and that s because you put all that energy, rocket engines put all that energy into the vehicle to allow it to travel that fast. that s the speed it takes to maintain orbit. when you come down, you ve got to take that energy out. so you ve got a heat shield and use air friction to take the energy out. the heat shield gets up to 3,000 degrees fahrenheit and the plaza going around the spacecraft burns the heat shield. there s some other thermal protection material around the rest of the capsule and kind of scars it. scorches it a little bit. and that s what you re seeing is the markings, the hot plasma that actually is burning a little bit. the heat shielding, the rest of the spacecraft. you are watching dragon now officially on its recovery vessel. doctor, can you talk to us about what happens next? they ll make sure that everything is secure inside the vehicle. they ll make sure that the pressure is equalized between
