Launch

Launch is a term used in several related contexts to describe starting or propelling something forward. As a verb, it means to begin or set in motion a process, project, campaign, product, or mission. As a noun, a launch can refer to the act itself, the vehicle or equipment used to perform it, or the formal ceremony that marks the beginning of an endeavor. The word comes from Old French lancer, to throw, itself from Latin lanc- “lance.”

In spaceflight and rocketry, a launch is the ascent of a rocket or spacecraft from a launch pad into space. It is a coordinated operation involving mission control, propulsion systems, and ground support, typically governed by a defined launch window that specifies the optimal time for reaching a desired trajectory or orbit.

In maritime contexts, a launch is the process of moving a vessel from land into the water, often accompanying a ceremonial event known as a launching. The term can also refer to a type of small boat used to transfer people or supplies from shore to a larger vessel.

In business and marketing, a product launch is the introduction of a new product or service to the market. It usually involves strategy planning, branding, production, distribution, and promotion, aiming to generate awareness and sales.

In computing and software, to launch a program means to start or run it. Operating systems and user interfaces provide mechanisms to launch applications, games, and other software.
