(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! |

Sorry to keep shining rays of optimism here, but circling back to Raytheon's claims, it looks like its more than pie-in-the sky. Here is a 2012 paper describing testing they did with a SiC CMOS at 400C:
http://www.raytheon.co.uk/rtnwcm/groups/rs...emp_article.pdf. So components that could theoretically function at ambient temperature on the (high plateau/peak) surface of Venus are in labs now. Assuming they're reliable, its just a question of time before they're commercially available. Finally - if you want something to add to your reading list, I stumbled upon this fantastic overview of the 2013 state-of-the art in high temperature SiCs |

Ah, behold the motivating power of proving someone wrong on the Internet! Thank you. The Raytheon paper is quite useful to me. http://www.raytheon.co.uk/rtnwcm/groups/rs...emp_article.pdf. (Still, power consumption at temperature is pretty high...) |
