primates in space -- is there any hope left?

Reminiscences on the End of the Hope for Primates in Space

Authors: Paul J. Werbos

This paper addresses the question of whether humans will ever be able
to settle space in an economically sustainable way and, if there is
still hope of this, where the greatest hope may lie. It reviews key
developments of the last 40 years relevant to this issue, such the
space shuttle, the National Aerospace Plane, the Russian Ajax effort,
nonlinear control challenges, challenges of developing a “skin” to
withstand re-entry, current space programs around the world, and key
markets for using such vehicles, such as energy from space and space
manufacturing.
