astronauts

Orbital mission crew

Astronauts are people trained to travel and work in space, typically as crew members aboard spacecraft or space stations.

The term comes from Greek words meaning "star sailor," though most astronauts operate in Earth orbit rather than among the stars.

Russians use the equivalent term cosmonaut, and the Chinese use taikonaut.

Two astronauts conducted a spacewalk to repair the solar panels.

The word often appears in contexts of childhood aspiration and human achievement.
