Human Factors
This full scale model of a portion of a rocket design that was built
at Marshall Space Flight Center to see
how the pieces would fit together. When this
rocket needs servicing, will a
human be able to get to the appropriate place safely and
without damaging the parts of the rocket? This is one of the
stages of the rocket.

If it costs $10,000 to lift a pound (half a kilogram) of
payload into orbit, calculate the cost of sending yourself
into space.
