The launch of the first crewed moon mission since the Apollo era is just a week away! NASA is preparing to launch its Artemis 2 flight on April 1.
This is a cool fact to impress your friends. The length of a day on Earth changes constantly, nudged by the Moon's gravitational pull, shifting winds in the atmosphere, and slow churning movements deep within the planet. It always has. Day length is, in a sense, a living measurement and one that ebbs and flows with the rhythms of a restless, dynamic world. But something new is happening.
