Launch techniques refer to the various methods used to initiate a spacecraft's journey into space. These techniques involve carefully calculated maneuvers that ensure the vehicle reaches the necessary speed and trajectory to escape Earth's gravitational pull. Common methods include using powerful rockets, such as those developed by NASA or SpaceX, which provide the thrust needed for liftoff. In addition to the initial launch, techniques also encompass the planning of flight paths and timing to optimize fuel efficiency and mission success. For example, gravity assists from other celestial bodies can be employed to gain additional speed without expending extra fuel, making missions to distant planets more feasible.
