00:00Why the heat shield is central. Normally, when you think of heat shields,
00:05you think of the atmosphere. But on the Moon, it's about something else.
00:09Extreme temperature fluctuations. During the day, over 120 degrees Celsius.
00:15At night, below minus 170 degrees. Origin is developing for Blue Moon.
00:22Multi-layer thermal protection systems that reflect radiation, store heat in a targeted way
00:28and keep critical systems stable. This is especially important for the avionics,
00:33tanks and energy systems. A lander that freezes at night is not a sustainable lander.
00:39We must not forget that a lunar night lasts 14 Earth days. And that's exactly why the heat shield
00:47is not just a detail, but mission critical. Zero. Oil off!
00:52Let's move on to one of the most important but least understood topics in spaceflight.
