Venus Interior Probe Using In-situ Power and Propulsion (VIP-INSPR), Phase I

Completed Technology Project

Project Introduction

Venus Interior Probe Using In-situ Power and Propulsion (VIP-INSPR), Phase I
We envision a novel architecture for Venus Interior Probes based on in-situ resources for power generation (VIP-INSPR). Proposed Venus probe is based on the generation of hydrogen from electrolysis at high altitudes using solar array, storing it in chemical hydride, utilizing it for altitude control in a balloon system and for power generation in fuel cell at lower altitudes. It is a challenge to have a durable power source in the low altitude environments, due to low solar intensity and low efficiency of RTG is inefficient. Primary batteries survive only for 1-2 hours. VIP-INSPR will refill hydrogen on one end and provide power on the other side continuously, thus enabling sustained exploration of the Venus atmosphere. More »
