offworld or freemasonry

The always fascinating BLDGBlog reports that a group of researchers have discovered how to create construction materials for future colonists on Mars using native building blocks in an environment apparently devoid of water. Heating sulphur to the point of liquefaction, it is mixed with soil to produce Martian concrete. The resulting bricks are relatively easy, light but sturdy, to use and are infinitely recyclable—in addition to being far less of a logistics investment in bringing supplies from home. Earthling settlers, given the weaker gravity of the planet, might be free to create impossibly ambitious cathedrals to exploration and discovery.
