Approach
In space and astronautical engineering, approach refers to the process of moving a spacecraft or satellite towards a target object, such as another spacecraft, a planet, or a celestial body. This process involves a series of maneuvers and calculations to ensure a safe and accurate approach. The approach phase is critical for many space missions, as it determines the success of tasks such as docking, landing, or flyby. During the approach, engineers and operators use various instruments and systems, such as cameras, sensors, and thrusters, to monitor and adjust the spacecraft's trajectory and velocity. The approach can be either autonomous or guided by ground control, depending on the mission requirements and the level of automation of the spacecraft. The approach distance and speed vary depending on the target object and the mission objectives, and can range from a few meters to thousands of kilometers.
