Your underground home on Mars (pictures)
More and more people are pushing to establish a colony on Mars, but just how will people live there? Here's an unusual concept for an underground cave dwelling.

Underground on the Red Planet
While space colonization plans such as Mars One seek applicants, Germany's ZA Architects has an intriguing plan for housing inhabitants: underground basalt caverns.
The voids would be carved out by solar-powered robots that land on the surface of Mars before humans set foot on it. They would take advantage of the basalt bedrock columns on the planet to create cathedral-like spaces underground, according to the plan.

Digger robots aside, there are other significant technological hurdles to creating an underground warren for humans on Mars. But Arina Ageeva of ZA Architects believes humans will be sent there within 10 years.
"Right now it...may not be possible, because such robotics do not exist, but generally we don't see anything unrealistic in this proposition," she told Dezeen. What do you think?
