There's not much you can iterate on Venus. It's a pressure cooker down there hot enough to melt lead. There's no way a probe can last more than a few minutes on

There's not much you can iterate on Venus. It's a pressure cooker down there hot enough to melt lead. There's no way a probe can last more than a few minutes on the ground. With a huge investment, you could maybe double that, but in any case you're going to hit diminishing returns really fast. I'm not sure we would even know how to design a refrigeration system that would work at those temps, let alone how to power it, and I'm also pretty sure we don't know how to make anything electronic that works at those temps.

We are close to having microelectronics that can function at Venus surface temperature and pressure. Examples tested include smallish circuits like a 555 timer [1] or a 256 pixel sensor array [2]. The Silicon Carbide technology seems very capable.
