Flying into space means leaving Earth's gravity behind. Astronauts hovering around the International Space Station may look like they're having fun in the weightless environment, but a lack of gravity can actually be a serious disadvantage when it comes to long-term health.
Well, researchers at CU Boulder have, so to speak, planned the first step towards artificial gravity devices installed in spaceships for the benefit of human travelers during space missions. The device – a large table spinning machine – may be a glimpse into the future.
Gravity and mass go hand in hand, and the generation of actual gravity is something we just can not do. With a centrifuge, however, it is possible to simulate the "weight" of gravity.
A carousel in your local park is an easy way to understand the consequence: the faster the ride turns, the firmer you have to stay in order not to be thrown off to become. Swap the carousel for a flat disc and position your body so that you lie with your feet out on your back and have the makings of a device with artificial gravity.
Living in an Ultra – A low gravity environment over a long period of time can damage the muscles and joints of the astronauts. For this reason, the ISS is packed with exercise equipment to keep spacemen in top condition, but that too can only do so much.  Disc-shaped artificial gravity devices, such as those built by CU Boulder, could be an easy way to enhance existing astronaut fitness routines and keep spacemen healthier for extended periods of time. However, there is a big hurdle that is just getting over: motion sickness.
As a person turns on the device, any movement of the head can lead to upset stomach, which is ideal for anyone, especially scientists, to travel through space. The team has been working to personalize the gravity routine for each individual ramp to the correct rotation speed. In this way, the researchers were able to bring all subjects to a speed of 17 revolutions per minute, without bringing them out of balance.
Looking to the future, the CU Boulder team is planning to further streamline the system and hire more volunteers who are slowly thinking about what might one day be the answer to keeping people happy and healthy in space.
