NASA to develop artificial gravity device

From a vacuum Martian airship to an artificial gravity chamber, NASA has revealed a host of new proposals that could push human and robotic exploration of space even further. The space agency is investing in 22 early-stage projects for further development, many of which tap into ideas that once existed only in science fiction. While the radical projects could take years before they can be used in a NASA mission, if at all, the agency says they could soon'expand how we explore the universe.' Among the proposals, NASA invested in a radical idea to create a sci-fi-like Mach Effect Thruster propulsion system. This would produce thrust'without the irreversible ejection of propellant, eliminating the need to carry propellant' NASA has selected Phase I and II awards for its 2017 Innovative Advanced Concepts portfolio.
