Don P. Mitchell's Web on Venus and the Venera missions should have the
answers you seek and then some here:
BTW, yesterday was the 44th anniversary of the first probe to "land" on
Venus performed by Venera 3. As they liked to say back then when a
lunar or planetary lander didn't quite land the way hey intended it to,
the prbe did carry the Soviet Coat of Arms. Of course the Soviets
would have real success with the second world from the Sun just a
few years later.

Subject: [FPSPACE] A technical Question Concerning the Venera Landers
Hello One and All,
I am currently teaching an IB Physics honors class. An interesting question came up regarding how the Venera landers were kept operational on the surface of Venus. Can anyone on this list direct me to any non-technical web sites for my students that discuss how the Soviet Venera landers were kept cool while operating on the surface of Venus? Did they use passive cooling or active refrigeration?
Also what materials and metals were used to construct the pressure vessels that housed the scientific instrumentation of the landers? Were they constructed from titanium or an alloy of titanium? Were the pressure vessels constructed in an analogous way to a thermos vessel or like a Dewar’s flask?
Many thanks for your kind help beforehand,
Alex Michael Bonnici
