NASA has been battling with the idea of sending Rover to Venus for years. Even though there is a similarity between the two planets in respect to size, mass, and overall composition, the similarities end there. On Venus the surface pressure is 92 times the pressure on Earth’s surface, identical to pressure nearly a kilometer deep in our oceans. The average surface temperature is 864 degrees Fahrenheit warm enough to melt lead. Sulphuric acid is present in the clouds; therefore it rains down corrosive liquid on the surface.
The longest any spacecraft has been on Venus is the Soviet Venera 13 lander that touched down in 1982. It stayed on for 127 minutes. To vanquish the expansive challenges of traversing the surface of Venus, NASA engineers are developing clockwork rover which means this rover will be dependent on mechanical systems rather than electronics rendering it to be defenseless to the harsh environment. The project named as Automaton Rover for Extreme Environments (AREE), was first propounded in 2015 by Jonathan Sauder, a mechatronics engineer at JPL who was inspired to build a mechanical Venus rover by the intricate levers and gears of mechanical computers.
Sauder said that Venus is an unwelcoming planet for intricate control systems that are available for Mars Rover. However, with a fully mechanical Rover the survival could extend till a year or so.The AREE project recently received a second round of funding under NASA’s Innovative Advanced Concepts program. This gives grants to engineers to advance from conception of the notion for future missions.
