It turns out that the surface of the moon is full of mysteries, particularly its fine dust covering. In the lunar soil, scientists hope to find clues about the formation of our solar system and glean answers about what other worlds might be like. It is also the destination for a new generation of crewed missions and the most likely site for the first permanent off-world human outpost. So not only will we want to learn how to live with this vexing substrate, we're also going to need to learn how to build with it. In other words, we're going to have to get our hands dirty. Or maybe, we're going to have to get our hands regolithy.
