The Stress Reliever will help several astronauts on their journey to Mars. The Stress Reliever can help disperse muscle pains in most parts of the body, including the neck, legs, arms, back, and shoulders. If the astronauts have pains in certain areas of their body it will prevent them from efficiently working out. If the astronauts stop working out, they will start to lose bone and muscle, and once they get back to earth, it will be very difficult to walk. This device is made of a polyamide, which is just nylon. The device is 3in by 3in by 3in. It is made up of a box with small round circular shapes on each face of the square. To use it you just rub it on the area of your body that hurts and after a while, it will start to feel better and you should be able to get back to exercise in no time. Use this device as often as you need to and as long as necessary. The Stress Reliever will be the next big thing for astronauts in space.
