Gravity Field
Gravity field refers to the distribution of gravitational forces in space. It is a fundamental concept in space and astronautical engineering as it affects the motion of spacecraft and celestial bodies. The gravity field is not uniform and varies depending on the mass and distribution of matter in space. Scientists use gravity field models to study the gravitational interactions between celestial bodies and to plan spacecraft trajectories. The study of gravity fields has led to the discovery of gravitational anomalies, such as the Lagrange points, where the gravitational forces of two large bodies balance each other, allowing spacecraft to remain in a stable position. Understanding the gravity field is crucial for space missions, as it affects the fuel consumption, trajectory planning, and stability of spacecraft.
