The novella “The Man Who Sold The Moon” by Cory Doctorow was published for the first time in 2014.

Greg Harrison has just received the result of a medical test that turned out negative. When he’s still shaken by having dodged a cancer, he accidentally runs into a young man who calls himself Pug, and he discovers they share some interests. Pug has built a 3D printer that uses sand to build bricks to assemble a yurt, and when he’s diagnosed with an incurable cancer, Greg decides to launch a version of it to the Moon, where it could use ground dust as a building material.
