What does liftoff mean?
Liftoff means the launch of a rocket or spacecraft, especially the moment it leaves its launch pad. The word also describes the beginning or rapid development of a new project, company, campaign, or other ambitious undertaking, as in the phrase “the liftoff of the project.” Its imagery is strongly associated with spaceflight: a vehicle rises against gravity, gaining speed and leaving its starting point behind. That sense of departure and momentum carries into figurative use, where liftoff often implies that something has begun successfully and attractively. The term is common in reporting on space missions, technology, business, and politics. It can be counted, with “liftoffs” referring to separate launches, but it is frequently used without an article in the fixed expression “liftoff.”
