A Laser Beam Reaches the Moon in Just Over One Second, Revealing the Precision Behind Deep-Space Measurement
A laser beam aimed at the Moon takes roughly 1.3 seconds to arrive, a deceptively simple fact that underpins some of the most precise measurements in modern science. The timing is central to lunar ranging experiments, which help researchers test gravity, refine Earth-Moon distance data, and support future space navigation.
