Dec 11, 2019 · Among the many challenges facing a Venus lander are those Sun-blocking clouds: Without sunlight, solar-power would be severely limited. But the planet is too hot for other power sources to survive. “Temperature-wise, it’s like being in your kitchen oven set to self-cleaning mode,” said JPL engineer Jeff Hall, who has worked on balloon and lander prototypes for Venus.

Venus isn’t the closest planet to the Sun, but it is the hottest in our solar system. Between the intense heat (900 degrees Fahrenheit heat, or 480 degrees Celsius), the corrosive sulfuric clouds, and a crushing atmosphere that is 90 times denser than Earth’s, landing a spacecraft there is incredibly challenging. Of the nine Soviet probes that achi...
Orbiters aren’t the only means of studying Venus from above. JPL engineers Attila Komjathy and Siddharth Krishnamoorthy imagine an armada of hot air balloons that ride the gale-force winds in the upper levels of the Venusian atmosphere, where the temperatures are close to Earth’s. “There is no commissioned mission for a balloon at Venus yet, but ba...

Feb 22, 2023 · The program uses the latest advances in high-temperature systems and a novel concept of operations to allow operations on the surface of Venus for 60 days or longer while the lander collects ...
There just isn't a pressure vessel big enough to hold a sample space craft that can contain that mix of heat, pressure, and corrosive elements without breaching. It was easy to build a refrigerated vacuum chamber to test Mars and Moon landers. Even then Mars landers have a 50% failure rate. The only place you could test a Venus lander was on Venus.

Sep 4, 2020 · With Venus, even our machinery can't survive past a few hours on the surface. Mining would be out, there would be no water. I really don't even see why there is any debate of Venus vs Mars.
