NASA demonstrates electronics for longer Venus surface missions

Current Venus landers can only operate on the planet’s surface for a few hours due to the extreme atmospheric conditions. The surface temperature on Venus is nearly 860 degrees Fahrenheit, which is hotter than most ovens, and the planet has a high-pressure carbon dioxide atmosphere. Because commercial electronics don’t work in this environment, the electronics on past Venus landers have been protected by thermal and pressure-resistant vessels. These vessels only last a few hours, and they add substantial mass and expense to a mission.

“With further technology development, such electronics could drastically improve Venus lander designs and mission concepts, enabling the first long-duration missions to the surface of Venus,” said Phil Neudeck, lead electronics engineer for this work.
