THE THREE LAWS
Johannes Kepler formulated these three laws in the early 17th century based on Tycho Brahe’s precise observational data. They describe the kinematics of planetary bodies: their shape, their speed, and their orbital period.

THE NAVIGATION FOUNDATION
Kepler’s laws are not just historical curiosities; they are the mathematical tools used by flight dynamics engineers every single day. When a spacecraft is launched, its trajectory is calculated using the elliptical paths predicted by these laws. If we didn't understand the relationship between distance and speed (the 2nd law) or the timing of orbits (the 3rd law), we would have no way to "intercept" a planet or maintain a stable orbit for a communications satellite.
