Sense: noun/1

Spaceflight is a technical term that refers specifically to the act of travelling beyond Earth's atmosphere, often used when discussing vehicles, missions, or the engineering behind them. Space travel is a broader, more everyday phrase that covers any journey through space, including future tourism. Space exploration puts the focus on discovery — sending probes or astronauts to learn about other planets and celestial bodies. Astronautics is the formal, scientific name for the field of spaceflight engineering. For example: 'She wrote a report on the history of human spaceflight' vs 'Many children dream of space travel when they grow up.'

Etymology

LatinOld EnglishEnglish

A compound word formed from 'space' (from Latin spatium, meaning 'expanse' or 'room') and 'flight' (from Old English flyht, meaning 'the act of flying'). The term came into common use in the mid-twentieth century as rocket technology made travel beyond Earth's atmosphere possible.
