To become a qualified NASA astronaut, candidates spend up to two years of training through intensive classes and simulations that help prepare for working in zero gravity, navigating around different parts of the space shuttle, and serving as each others' emergency medical technicians.
In the past, astronaut training meant dives in a "neutral buoyancy lab," a giant pool that holds 6.2 million gallons of water, and spending time at NASA's "space vehicle mock-up facility," a life-sized model of the space shuttle orbiter and parts of the international space station (ISS).
The mixed reality system, developed in collaboration with Epic Games' Unreal Engine to create shows instruments on board the ISS, including different exercise machines and tools that astronauts use for maintenance work there.
The mixed reality ISS app sweeps astronauts-in-training off their feet with an "active response gravity offload system."
It works in conjunction with a robotic crane that makes the trainee feel like they would in micro gravity.
