Systems Design Study of the Pioneer Venus Spacecraft Final Study Report Appendices to Volume Ⅰ Sections 3-6 (Part 1 of 3)

摘要

The objective of this study has been to attain the lowest-cost, reliable spacecraft to accomplish the mission. The study has been in the framework of a sequence of definitions of the complement of scien?tific instruments and includes two parallel studies, one using the Thor/ Delta launch vehicle and the other, the Atlas/Centaur.nThe study shows a definite cost advantage when the Atlas/Centaur is used for the probe mission. The relief of weight and volume con?straints allows a substantial use of existing and proven hardware and technology for the probes and increases the commonality of the hardware between the large probe and the three small probes and between the probes and the probe bus.
