Abstract: In response to the recommendations by the National Research Council (NRC), NASA's Solar System Exploration (SSE) Roadmap identied the in{situ exploration of Venus and Jupiter as high priority science objectives. For Jupiter, deep entry probes are recommended, which would descend to ~250 km - measured from the 1 bar pressure depth. At this level the pressure would correspond to ~100 bar and the temperature would reach ~500°C. Similarly, at the surface of Venus the temperature and pressure conditions are ~460°C and ~90 bar. Lifetime of the Jupiter probes during descent can be measured in hours, while in{situ operations at and near the surface of Venus are envisioned over weeks or months. In this paper we discuss technologies, which share commonalities in mitigating these extreme conditions over proposed mission lifetimes, specically focusing on pressure and temperature environments.
