Where astronauts float
In space describes location or activity beyond Earth's atmosphere, in the vacuum between celestial bodies: The astronauts conducted repairs in space, The satellite will remain in space for decades.
The phrase distinguishes extraterrestrial environments from conditions on Earth's surface: Objects in space experience weightlessness.
