The absence of gravity in Space alters what we take for granted on Earth. In microgravity the human body experiences significant postural and perceptual changes. From an architectural perspective these transformations have profound epistemic implications on the man/environment relationship.Weightlessness exacerbates problems relating to orientation, mobility and environmental interface. In order to choreograph human/machine interface within physically and emotionally supportive body envelopes the characteristics of the interface morphology of human mobility in microgravity must be understood.If weightlessness can modify our bodily experiences, it will certainly lead our collective consciousness to new ways of knowing. Thus, the physics of microgravity must be the primary guidelines to designing crew accommodations for an orbital outpost.Of all the people I've spoken to about the experience of space, only those closest to me can begin to understand ...............Unless you actually go and experience it yourself you will never really know.ROBERT CENKER STS-61 C COLUMBIA.
