Mission To Venus

Venus is the closest planet to Earth (min distance of 40 M km vs 56 M km for Mars). One of the major problems of a Lander (Rover) on another planet is the energy source. Solar panels are sensitive and their efficiency drop with dust and heat. On the other hand surface of Venus is about 465 °C. My proposition of direct heat to electricity conversion would generate continuous high power for the Venus Lander and negate the need of a bulky battery. (https://fabsole.com/TEG.aspx) Venus has about 465 °C temperature, almost 100 ATM pressure and highly acidic atmosphere on its surface.  That's a challenge for the Lander designers however it is possible with todays technology. Electric motors and magnets wouldn't work at that temperature. Therefore the Lander should utilize pneumatic systems with stainless steel pipes and pistons. Lander's movement and drilling would be conducted using pneumatic hydraulic systems. Thermionic generators keep inside the robot cool and generate continuous electricity. Even than SiC chips should be used instead of Si for reliability. The dense atmosphere of Venus helps lifting of the Lander easier. Therefore the Lander can fly and walk like a fly and explore much larger areas than a Lander on Mars can achieve. Finally I believe there are more life forms can be found on Venus than on Mars. (Animals found living underground near deep-sea hydrothermal vents. Life flourishes around the vents - including giant tubeworms reaching lengths of 10 feet (3 meters), mussels, crabs, shrimp, fish and other organisms beautifully adapted to this extreme environment. The giant tubeworms do not eat as other animals do. Instead, bacteria residing in their body in a sack-like organ turn sulfur from the water into energy for the animal.)
