The design of To inform the Earth-bound public of Mutopia is an example of how creativity has Mutopia, we can start with efforts similar to the been enhanced by our multi university team of outreach efforts we did to inform our local engineers, bio inspired designers and social community of the RASC-AL program. An scientists. A central feature necessary to this overview of RASC-AL, an introduction to lunar base is gravity. Gravity, generated in the biologically inspired design, some of the mag-lev supported Moontrifuge, provides a challenges faced when designing for a lunar physiologically-friendly environment needed inhabitation, and the biologically inspired for healthy human life.
