This Soviet Robot Survived 127 Minutes on Venus. It Was Built for 32

In 1982 the Soviet lander Venera 13 was built to last about 32 minutes on Venus, survived 127, and sent back the first color photos of its surface.
Why Venus is the worst place in the solar system: 465 °C, hot enough to melt lead, pressure like 900 m underwater, sulfuric acid clouds, a day longer than a year and the fight over life in the clouds.

If you had to spend one hour on Venus, would you pick the crushing surface, the acid clouds, or a balloon floating 50 km up? Tell me in the comments ????
