Venus’s spider is a robot used to make research on Venus’s surface and gather samples. It is a derivative of the Lunar Tumbler I had proposed earlier. It will be released from the Reusable Solar Stage Rocket. The egg-shaped capsule will contain the rocket propellent and the spider robot in the middle. The propellent will be consumed to slow down the capsule during descent to Venus. The wings attached around the capsule will generate lift and induce drag which both help to increase the flight duration and allow smooth landing on the targeted location. The tumbler like design will be bottom heavy to allow the capsule sit on its bottom. After landing, the shell will be cracked by controlled detonation. The robot will be released.
The robot needs to operate around 400 degrees Celsius. On top of the robot there will be a vertical wind turbine attached to a heat pump compressor which is air cooled. The heat pump will actively cool the electronics bay using the Venus’s strong wind. The electric will also be generated by this wind turbine. The motors controlling the legs of the robot will be placed outside. The motors will utilize high temperature magnets such as Alnico. The front legs of the robot will double as arms to grab samples from the ground.
The samples gathered by these spider bots will be transferred from ground to the flying base by a transporter capsule. The capsule will be spherical shaped to have minimum surface area and maximum propellent. It will also have wings attached on its sides to utilize air lift. It will consume methane and oxygen as rocket propellent which are generated from Venus’s atmosphere by the floating base. The transporter capsule is the weakest part of this whole idea. Sand blaster like dust storms of Venus limit the alternatives.
