ESA scientists created a special lunar regolith by crushing an old meteorite to get the necessary material. The dust from it was used to 3D print the bricks, which connect to each other just like regular Lego pieces. Experts empha

The amount of work to simplify the Raptor engine, introducing secondary flow channels and adding regenerative cooling for exposed components, has been staggering. As a result, the Raptor 3 requires no heat shield, which reduces mass, eliminates the complexity of the heat shield, and the fire suppression system. It is also lighter, has more thrust, and higher efficiency than the Raptor 2. Mass prod
