A record of stardust, quietly accumulating.

Timeline

Space Exploration Timeline, 1609–2030: From Kepler's Laws to Artemis

The orbits were worked out long before anything could fly them

Space-exploration timelines usually begin with Sputnik in 1957. But why a satellite does not fall down had been explained by Newton in 1687; what was missing was any way to throw something that fast. This timeline runs the theory of orbits and rockets, and what was learned only by going, along the top of the axis, and what actually flew along the bottom — 42 entries, from Kepler turning planetary orbits into formulas in 1609 to a spacecraft due at Europa in 2030.
