Affordable housing in outer space: Scientists develop cosmic concrete from space dust and astronaut blood. Transporting a single brick to Mars can cost more than a million British pounds -- making the future construction of a Martian colony seem prohibitively expensive. Scientists have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.

I wish there was more on how to make bricks on mars could be elaborated soon for us to get carefully find out.
