- The main constraint on the spacecraft's survival on the surface of Venus has
- been the temperature. The Soviets often chilled the interior of their
- spacecraft before parachuting them down to the surface. 900F is about
- 2 to 3 times the temperature of your conventional oven. Lead melts at
- that temperature. As a comparison, the Viking landers were sterilized by
- heating them to 235F for 24 hours. Anything on the surface of Venus is
- literally being roasted.
