The spincubator is very important for babies on Mars in the future. On Mars, the gravity is less than what it is here on Earth. In general, when there is less gravity, a human's heart finds pumping blood throughout the whole body troubling. All of the body's blood stays in the upper part of the body. This causes higher blood pressure, muscle, and head problems. The spincubator is an incubator for babies in space that generates gravity by spinning. This spinning motion helps pull the body's blood toward the parts of the body that doesn't have any. This design is the mechanism that would be connected to the incubator to spin it and generate gravity. Since it is mostly gears, it will be made of ductile iron, the same material used to create gears.
