Blast off
Meaning
To launch into space or begin a rapid, powerful ascent or departure.
Origin
Before humanity could reach for the stars, the concept of an explosive departure was already brewing in language. The word "blast" itself, tracing back to Old Norse blástr, described a powerful expulsion of air or a sudden, forceful event. As the scientific dreams of rocketry took shape in the 20th century, the imagery became literal: rockets would generate an immense, controlled "blast" of exhaust to achieve liftoff. Combining this forceful action with the clear indicator "off" to signify separation and ascent, "blast off" became the iconic, vivid phrase, cementing itself in the mid-20th century as the definitive call for a rocket's dramatic launch into the cosmos.
