Abstract Title

Surface Analysis of Venus's Atmosphere and Geophysical Events (SAVAGE)

Abstract

The 2017 NASA Space Academy at Glenn Research Center has developed an innovative lander/orbiter concept to obtain long term scientific data on the surface of Venus. The science objectives of this study were driven by the 2013-2022 Planetary Science Decadal Survey and the Venus Exploration Analysis Group (VEXAG) 2014 Final Report. Recent developments in high temperature electronics eliminate the need for insulated or cooled pressure vessel, creating the opportunity for smaller and cheaper extended lifetime landers. The objective of this concept study is to propose a preliminary design for a technology demonstration of high temperature sensors and electronics on a scalable long-duration surface probe and orbiter system that would return the first in situ temporal data on the climate and seismic activity of Venus. Sensitivity studies in surface probe mass scaling were applied and resulted in an increase in science return. Power and communication studies revealed that a mission consisting of five surface probes and two CubeSat communication orbiters are potentially feasible and worth future study.
