With a massive number of active volcanoes regularly spewing sulfur, ash, and other particulates into its atmosphere, Venus has an average surface temperature of more than 860 degrees Fahrenheit.
This intense heat, and the combination of atmospheric pressures more than 90 times what we experience on the surface of the Earth, makes the surface of Venus nearly impossible to explore and study. Venus has a track record of devouring probes sent to its surface in a matter of hours.
The ambitious NASA plan is to build a blimp city that will float 30 miles above the surface of Venus in a habitable zone and where astronauts can study the inho……………. continues on Chinatopix
