The Moon is Earth’s only natural satellite—a rocky, cratered body about one‑quarter the diameter of Earth, orbiting at an average distance of approximately 384,400 km. It influences tides, stabilizes Earth’s axial tilt, and was formed about 4.5 billion years ago following a collision between Earth and a Mars-sized object.

In early November of 1967, a dramatic night launch of an Atlas Centaur rocket from Cape Canaveral lofted the successful Surveyor 6 spacecraft toward the Moon. The Surveyor series of robotic probes carried out the first US lunar soft landings in preparation for the Apollo program. Still in use today, Atlas Centaur rockets launched many lunar and planetary probes in the 60s and 70s.
