While it is illegal to own Apollo return samples, we obtain moon dust from meteorites that originated on the Moon, fell to Earth, were found, and identified in the lab. The Moon rocks that Apollo astronauts Buzz Aldrin, Neil Armstrong, and the other moonwalkers brought back to Earth did, however, help meteorite scientists to identify a small number of meteorites as being of lunar origin.
How do we get moon dust? Like sawdust produced when a wood is sawn, lunar meteorites produce “Moon dust” when a larger specimen is cut into slices in the lab. We collect this precious material and have added it to the ink used to screen print our Moon and Mars t-shirts. That’s right: your La Luna shirt contains actual dust from a meteorite carried here all the way from the moon!!
