A great recap of how we learned about Venus and how Russia sent back pictures. Given the pressure, acid rain, and 900 degree temps, it was feat of engineering, especially for the time, to get the probes to last until they touched down and completed their mission. And of course the probes didn’t last very long in those conditions. And it makes you recognize just how perfectly the earth is setup for human life to flourish when everything else is so deadly and lifeless.
