  Kepler’s laws describe the motion of planets around the Sun, establishing that orbits are elliptical, planets sweep out equal areas in equal times, and the square of the orbital period is proportional to the cube of the semi-major axis. These laws provide a fundamental framework for understanding orbital trajectories and predicting spacecraft positions. For example, Kepler’s laws are used to calculate the time it takes for a satellite to complete one orbit around Earth. In introductory aerospace engineering, these laws are used to model simple orbital scenarios and develop an intuition for orbital behavior.

  Orbital elements define the size, shape, and orientation of an orbit in space. Six parameterssemi-major axis, eccentricity, inclination, longitude of ascending node, argument of periapsis, and true anomalycompletely specify an orbit. These elements are used to characterize and compare different orbits. For example, geosynchronous orbits have a specific semi-major axis and inclination to remain fixed over a point on Earth. Students in introductory aerospace engineering learn to calculate orbital elements from position and velocity vectors and to visualize orbits in three dimensions.

• Orbital Maneuvers and Delta-V

  Orbital maneuvers involve changing a spacecraft’s orbit, typically using propulsion systems. Delta-V (v) represents the change in velocity required to perform a maneuver. Minimizing delta-V is crucial for mission planning, as it directly impacts fuel consumption and mission duration. For example, a Hohmann transfer is a common maneuver used to transfer between two circular orbits. Introductory aerospace engineering coursework introduces basic orbital maneuvers and the associated delta-V calculations, providing a foundation for more advanced mission design.

• Perturbations and Orbital Stability

  Real-world orbits are subject to perturbations from factors such as the gravitational influence of other celestial bodies, atmospheric drag, and solar radiation pressure. These perturbations cause deviations from ideal Keplerian orbits. Understanding these effects is crucial for long-term orbit prediction and station-keeping. For example, the Earth’s oblateness causes perturbations in low Earth orbits.
