Time Ticks Faster on The Moon. Now We Know Precisely How Much.

Since astronauts departed the lunar surface for the last time 52 years ago, time has ticked on by. Relative to us Earthlings, the Moon has pined for our return just a little longer – by roughly 1.1 seconds. It doesn't sound like much, and neither does the 57 millionths (0.0000575) of a second that the Moon's time stretches ahead compared to that of our home planet each day. But that crucial result of a new study from NASA scientists could be the difference between navigation systems syncing up as the US space agency launches its long-awaited crewed missions to the Moon and beyond.
