"Launch" refers to the process of starting or introducing something new, such as a product, service, or project. For example, when a company like Apple unveils a new smartphone, they hold a special event to showcase its features and capabilities. This moment is crucial for generating excitement and interest among potential customers. In the context of space exploration, "launch" describes the moment a rocket, like SpaceX's Falcon 9, lifts off from the ground. This event marks the beginning of a mission, sending satellites or astronauts into orbit. Successful launches are vital for advancing technology and understanding our universe.
