text: NASA is working on other approaches to studying venus. For example, like electronic made of silicon and it been tested in chamber simulation the chaos of Venus surface and have lasted for three weaks in such conditions. They have another project to look back an old technology call mechanical computers. This devices make calculation by using gears and levers and do not require electronics at all. Modern computers are enormously powerful, flexible, and quick but tend to be more delicate when it come to exterme physical conditions. By comaprison, systems that use mecanical parts can be made more resistant to pressure, heat, and other forces.   Dear principal,
