(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! |

The Science journal has a new article about the recent advances in high-temperature electronics for Venus missions, especially silicon-carbide chips developed at the Glenn center:
http://science.sciencemag.org/content/358/6366/984 The current record holder has 175 transistors and is already considered for actual missions. The article also mentions a separate work done at JPL using mechatronics (gears and stuff) instead of transistors, which sounds positively like steampunk. |

The topic is a bit timely, with Mars Insight launching soon: a low-bandwidth lander with a conventional camera, conventional laser spectrometer, and conventional mass spectrometer plus high-temperature electronics supporting a seismometer could be a heck of a mission. The first three instruments would work for an hour and give us observations upon arrival, while the seismometer would work for months, at least. I suspect that Venus has enough quakes that a few months would be very informative. It'd be really nice to drop two of these at different latitudes of the same longitude and locate the epicenter of the quakes.
