AI overview
Weightlessness, or microgravity, is the condition astronauts experience in space where they float freely because they are in continuous free fall around Earth rather than being supported by a surface. It matters because understanding and adapting to weightlessness is essential for astronauts working on space stations like the International Space Station.

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) or, misleadingly, zero gravity.
