Venus Clouds Offer Earth-like Pressure, Sparking Airborne Exploration Plans
TL;DR
At about 50 kilometres above Venus’ surface, the atmosphere’s pressure and temperature reach Earth-like levels (around 1 atm and 30–75°C), prompting NASA’s HAVOC study to revisit the idea of atmospheric exploration with airships and balloons. While still uninhabitable and not a surface mission, this narrow band in Venus’ clouds could enable long‑term measurements and study of climate and chemistry, offering a different target than Mars for future exploration.
- About 50 kilometres above Venus’ surface, the crushing heat and pressure below give way to temperatures and air pressure surprisingly close to Earth’s, a region NASA has described as the most Earth-surface-like environment in the solar system — at least b Space Daily
