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.
