00:00Imagine if the Orion capsule landed on different planets in our solar system.
00:04What would happen to its heat shield? On Mercury, the temperature can reach about 430 celsius.
00:12So the heat shield would get extremely hot. On Venus, it is even worse. The surface temperature
00:18is around 465 celsius or hot enough to melt lead. The heat shield would face intense heat.
00:26On Earth, during re-entry, the heat shield can reach about 2700 celsius because of the
00:34friction with the atmosphere. On Mars, the atmosphere is thin. So the heat would be much lower.
00:41But the capsule would still need protection. On Jupiter or Saturn, there is no solid surface.
00:48The capsule would face huge pressure and strong storm instead. Each world in our solar system
00:55is different. So the heat shield must be strong enough to survive extreme temperatures.
