Everything with mass has gravity, she points out. Scientists could try to harness real gravity, McKinnon says. And your stomach would still be awfully confused. Fluids would still be able to collect in the upper body. But being stuck to the floor isn’t the same as gravity.

The work required to walk against a magnet might also limit bone and muscle loss in space. The attraction between the metal and the magnet would help someone walk along the floor.

All an astronaut would have to do is wear metal boots. The flow of electric current produces magnetism. “You can create that magnetic field by running electricity around in circles,” she says. One approach would be to “use electricity and magnetism as a way of substituting for gravity,” McKinnon explains. And at least a few of the simpler tactics might not be that far off. In fact, notes Mika McKinnon, “We know a lot of ways to have the same effect as gravity using other forces.” She is a physicist with the Search for Extraterrestrial Intelligence (SETI) Institute. This can cut off hearing.Īlso, floating around in zero gravity makes you puke. Without gravity, blood and other bodily fluids don’t flow normally and can collect in the upper body. In the long term, our bones and muscles don’t work as hard in a gravity-free environment. So as people travel to the Moon or Mars, their pull toward Earth quickly weakens, which leaves them floating. This is why we stand firmly on the ground no matter where on Earth we are. Objects with a lot of mass - such as Earth - attract other objects toward their centers. It attracts objects with mass toward each other. It’s that in those fictional worlds, artificial gravity exists.

The difference isn’t just because the books, movies and TV are fiction. In real life, though, astronauts in space float. To make the mixed-reality simulation of gravity even more immersive, it also works with an "active response gravity offload system", basically a crane that flies astronauts around to simulate zero, lunar or Mars gravity.In lots of books, movies and TV shows, people on spaceships walk around like they would on Earth. The training includes simulated maintenance, letting you use the Vive's control wand to grab tools and other objects aboard the ISS. NASA ISS astronauts that have tried the sim say it closely matches what it feels like to handle objects in zero G. When you look up at the digital "sky," your pupils must dilate before you can see any stars, the same thing astronauts experience in space. "The more realistic the training feels, the faster you can respond in real-world, critical situations, which could save your mission or even your life." As Ars Technica noted after trying it out earlier this month, the VR is realistic enough that it can even simulate blooming.

The setup uses "cutting edge graphics and physics simulations to increase the sense of presence," says NASA Software Engineer Matthew Noyes. However, the training SIM NASA is developing with Unreal Engine is different altogether, and they appear to be using both the Oculus Rift and HTC's Vive headsets. NASA recently teamed with Oculus on Mission:ISS, a consumer education VR experience aboard the ISS. The company that helped them build the sim, Epic Games' Unreal Engine, recently unveiled a video showing exactly how that works. However, virtual reality has become a new option, allowing astronauts to do realistic training for things like maintenance in an accurate, simulated zero-G environment.

To train ISS astronauts, NASA uses physical mockups, zero-G " vomit comet" airplane rides, neutral buoyancy (underwater) and other pricey and complex schemes.
