Space Ghost compares the experiences of astronauts and prisoners,
using popular depictions of space travel to illustrate the physical and
existential aspects of incarceration: sensory deprivation, the perception of
time as chaotic and indistinguishable, the displacement of losing face-to-face
contact, and the sense of existing in a different but parallel universe with
family and loved-ones.

Physical comparisons such as the close living quarters, the
intensity of the immediate environment, and sensory deprivation soon give way
to psychological ones: the isolation, the changing sense of time, and the
experience of earth as distant, inaccessible and desirable. The analogy extends
to media representations that hold astronauts and prisoners in an inverse
relationship: the super citizen vs. the super-predator. Astronauts, ceaselessly
publicized, are frozen in time and memory whereas prisoners, anonymous and
ignored, age without being remembered.

The end of the video introduces the notion of the "phantom
zone" taken from Superman to describe incarceration as an in between space,
a no man's land or a warehouse. A letter from an inmate explains how the
space/time continuum can become reconfigured in prison: The time really goes by
fast here. You can do years in prison and it seems like no time at all. That's
because you don't remember any of the time you did. And that's because there's
nothing to remember.
