Galileo Atmospheric Entry Probe System - Design, development, and test

The overall development of the Galileo Atmospheric Entry Probe System is described. The Probe will be carried to Jupiter by the Galileo Orbiter and released on an entry trajectory 150 days before entry. A complement of seven science instruments will measure the near-Jupiter radiation field and the characteristics of the Jovian atmosphere from a distance of about 5 Jupiter radii above the 1-bar level down to levels in the 10-20-bar range. Probe data are to be transmitted to earth via the Orbiter. System requirements are discussed. Probe design features and those features of the development test program peculiar to entry probes are described.

Probing a planetary atmosphere - Pioneer Venus spacecraft description

This paper describes the four Pioneer Venus probe spacecraft which will explore the atmosphere of Venus in mid-December, 1978. The probes, one large and three small, will carry a complement of sixteen scientific instruments which will make measurements from entry (200 km-altitude) down to the planet surface. The surface environment, approximately 770 K temperature and 95 bar. pressure, leads to a design in which the equipment complement is housed in internally insulated, spherical pressure vessels. Entry deceleration and stabilization are provided by 45 deg. half-angle conical forebodies, heat protected by carbon phenolic ablative heat shields. For the large probe, a parachute provides additional retardation between 67 and 44 km altitude, a region of extreme scientific interest.

Pioneer Venus probe design

The summary provides descriptions for a set of probes designed to explore an inner rather than an outer planet, and designed to survive to 100 bars rather than 10 bars. The probes carry a variety of scientific instruments and their supporting integrated subsystems are adjusted to Venus environmental conditions.

System design of the Pioneer Venus spacecraft. Volume 5: Probe vehicle studies

A summary of the key issues and studies conducted for the Pioneer Venus spacecraft and the resulting probe designs are presented. The key deceleration module issues are aerodynamic configuration and heat shield material selection. The design and development of the pressure vessel module are explained. Thermal control and science integration of the pressure vessel module are explained. The deceleration module heat shield, parachute and separation/despin are reported. The Thor/Delta and Atlas/Centaur baseline descriptions are provided.
