Thermal imaging- using the same principle that an Apache uses to find a-holes planting IEDs in Iraq at night. The surface of Venus is hot- but Magma is hotter.

I still get a kick out of the images of the surface of Venus that the Soviet lander sent back in the Seventies. Might be only dust and rocks, but it’s Venus.

This statement is from your link:

All of the spacecraft that ever landed on Venus are probably still there today.

Unless they landed on the bad side of town and were chopped for parts?
