Going undersea requires a much more robust design. Pressure does horrendous things to technology. |
The objective is to provide an analog close to space where the consequences are really life and death, ... Rookies can make their mistakes before they get to space. |
The state of technology (for undersea exploration) is still in its infancy, ... We have 90 years and two countries' worth of experience in space exploration -- and maybe a dozen real serious underwater habitats. A lot more manpower and GDP has gone into space exploration. |
We're operating very close to the conservative end of undersea habitation. The challenges go up exponentially as you go deeper. |
