(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! |

However, there are alternatives.
For folks with Sirius satellite radio (to cite a terrestrial example of something you might have), the satellites are in highly elliptical polar orbits, with their high points over the northern hemisphere. This means those satellites spend very little time over the south pole, but quite a bit over the north pole (but at a great altitude) So if you had a probe on the surface, and it was anticipated to last long enough for this to matter, you might want to put it poleward and have an orbiter in a path similar to the Sirius radio satellite. {BTW, Sirius did not invent that technique, the Soviets used it extensively for many years prior} |
