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.

Невесо́мость — состояние, в котором отсутствует сила взаимодействия тела с опорой или подвесом (вес тела), возникающая в связи с гравитационным притяжением. Иногда в качестве синонима названия этого явления используется термин микрогравитация, что неверно (создаётся впечатление, что гравитация отсутствует или пренебрежительно мала).
