Which maneuver is known for changing the size of the satellite's orbit efficiently?

1. Out of Plane Maneuver

2. In Plane Maneuver

3. Transfer Orbit Maneuver

4. Orbital Insertion Maneuver

The correct answer is: In Plane Maneuver

The in-plane maneuver is recognized for its efficiency in changing the size of a satellite's orbit. This maneuver involves adjusting the velocity of the satellite within the same orbital plane, effectively allowing it to raise or lower its orbit by altering its speed. When a satellite performs an in-plane maneuver, it can accelerate or decelerate relative to its current orbit. For instance, if the satellite increases its speed, it will move to a higher orbit, while decreasing its speed will cause it to descend to a lower orbit. This type of maneuver is particularly fuel-efficient because it capitalizes on the existing orbital momentum without the need for complex changes to the orbital plane. In contrast, the other options pertain to different types of maneuvers that serve different purposes. The out-of-plane maneuver, for instance, is used to change the inclination of the orbit but is not primarily focused on resizing the orbit. The transfer orbit maneuver is typically implemented to move a satellite from one orbit to another, often involving multiple stages of thrust, whereas the orbital insertion maneuver refers to the process of entering a new orbit from a different trajectory, which may not be as efficient for merely resizing an orbit. Thus, the characteristics of the in-plane maneuver align perfectly with the goal of efficiently
