In our lifetimes, we may see people living on the moon.
Olympus is a NASA-funded project by the construction tech company ICON, which seeks to create human-supporting infrastructure on the moon, including roads, landing pads, blast shields and, eventually, habitats.
Still at its research and development stage, Olympus is going to first test lunar surface samples brought to Earth from Apollo missions in order to observe their mechanical behavior in simulated moon gravity. This will help develop prototypes for a future full-scale 3D printing system that might one day, perhaps in the coming decades, build infrastructure on the moon.
