Manned versus unmanned space-based astronomy.

Abstract

Discussion of the pros and cons of manned and unmanned space-based astronomical observatory systems. Rather than compete with one another, manned and unmanned systems, it is felt, should complement themselves mutually. The paramount factor inhibiting the growth of both manned and unmanned systems is shown to be the high cost per pound of payload equipment. The main hope for reducing this cost is the advent of a space station or shuttle sortie mode of operation in which the frequency of flights will reduce the necessity to guarantee experiment success. This, in turn, should reduce the complexity of experiment management and the cost of experiment hardware.
