(MOD NOTE: Started a new topic for this discussion to continue. Please remember the 'no sci-fi engineering' provision of rule 1.9. Have fun!)
Also, since I'm thinking about surface operations on Venus, the state-of-the-art in high temperature electronics has advanced quite far in the past decade. Its now possible to buy off the shelf chips from vendors designed to operate at the 250-300 C range. Meanwhile basic functionality has been tested at and beyond the temperatures needed for long-term surface operations on Venus: http://www.grc.nasa.gov/WWW/SiC/ http://www.gizmag.com/extreme-silicon-carb...ctronics/16410/ http://www.grc.nasa.gov/WWW/SiC/publicatio...Contact2010.pdf Another decade or so and a long-term Venus lander could be possible with (practically) off the shelf electronics! |

One small thing in favor of high temperature electronics for Venus is that, while very high, the temperature is relatively stable. You don't need components that works at both 20 C and 450 C. They only need to work at 450+/-50 C, which is probably somewhat easier task. The lander can have a separate set of electronics for the cruise and native high temperature ones after landing.

You don't need components that works at both 20 C and 450 C. That would enormously simplify testing, though. For our Venus proposals we spent a fair amount of time worrying about how we could even simulate the environment in any practical way. How do you put a scope probe on something that has to be at 450C to work? -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
