These Lego bricks made from a meteorite could help scientists build the first structures on the moon

The European Space Agency is 3D-printing bricks made with the dust from a 4.5-billion-year-old meteorite.

Lego bricks have been fodder for a number of unexpected projects over the years, from making sounds for ASMR videos to teaching kids how to read Braille. Now, the bricks might be used for something truly groundbreaking: helping to build the first-ever structures on the moon.
