Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [1] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
Your Own Zero Gravity Laboratory. No experienced engineer launches into space with their fingers crossed. Test both early- and late-stage space tech in Lunar, Martian, and Zero gravity.
To help the astronauts adapt, NASA, as part of their training, subjects the astronauts to such an environment every day. The enclosed region of “zero” gravity is not located in space, but is created right here on Earth. The question is… how does NASA achieve this?
Floating in zero gravity (zero-G) is something that many people have fantasized about. The idea of drifting through the air without the weighty pull of Earth's gravity is, for some, incredibly...
weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.
The sensation of weightlessness, or zero gravity, happens when the effects of gravity are not felt. Technically speaking, gravity does exist everywhere in the universe because it is defined...
Zero gravity flights are used to simulate a zero gravity environment for astronauts in training. Find out how zero gravity flights simulate weightlessness.
