Whose idea led to the use of accurate star charts for navigating the Moon and planets in early space missions?
Quick Answer
That was largely built on celestial mechanics developed by Isaac Newton and later refined by many astronomers. Newton's work made precise orbital prediction possible for navigation.
The Full Story
Isaac Newton's laws of motion and universal gravitation provided the foundation for calculating the positions of planets, moons, and spacecraft. By the 20th century, that mathematics had become essential for mission planning and navigation in space. Accurate ephemerides and star charts depend on the same physics Newton established in the 1680s. Without that framework, early lunar and planetary missions would have been far harder to plan.
