(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! |

Its been a while, but there continues to be a steady drumbeat of every higher temperature commercial components that inch closer to (or even surpass) Venusian temperatures.
Some examples: GE Announces 250+ C rated Transient Voltage Suppressor (Surge protector) Roundup of high temperature Elastomers (think, Vulcanized Rubber), rated to 450 C Ceramic packaging rated up to 1,000 C (!) This recent conference mentions a talk on a diamond MOSFET (transistor) that worked in temps ranging up to 400 C (10K to 700C in the more detailed notes!). A recent overview of high temperature electronics note the demand for 200-250 C rated components is growing - with ceramic, Tantalum, and film based capacitors competing in that temperature range. |
