ZA Architects Propose an Underground Colony on Mars   With the
advent of technologies such as 3D printers that can operate in
space and genetically engineered brick-forming bacteria, the
idea of building a colony of Mars no longer seem so far-fetched.
The German firm, ZA Architects is proposing plans for a large,
underground network of caverns to begin the population of the
Red Planet. Relying primarily on robots, the machines will pave
the way for humans to eventually live on Earth’s neighbor.  This
is eoic.
