Pioneer Venus 2
By Emerson Cody
Pioneer Venus 2's goal was to collect data during independent atmospheric entry into Venus.
From the probes sent out by Pioneer Venus 2 it indicated that between 10km+50km from the planets surface there is no convection[heat] in the Vennsian atmosphere. The probe that was used by Pioneer Venus 2 transmitted data from the surface of the planet for over an hour before succumbing to the high temperatures. Power depletion so this means for humans it is too hot for us to live on Venus.
