(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! |

In order to investigate possible ongoing volcanism, I'd presume, that one would be interested in longer-lasting atmospheric spectrometry.

Long-term monitoring of atmospheric composition would certainly be interesting and perhaps the instrument and its logic could be done with high temperature electronics. It's an open question as to how long an interval would be likely to detect changes, which has been done from orbit, revealing roughly one spike in SO2 per decade. Perhaps smaller spikes are more frequent.

Over two years old now, a proposed Venus surface mission that would use high-temp electronics for long-term monitoring of seismic activity and atmospheric changes.
The upshot is, something like Viking and Insight for Venus, with a surface mission of 120 days for one or two landers. Note that the slow rotation of Venus constrains the choice of landing sites whether or not the landers accompany an orbiter that could perform data relay. https://www.lpi.usra.edu/vexag/reports/SAEVe-6-25-2018.pdf |
