Summary

Story summary

National Aeronautics and Space Administration (NASA) confirmed that China's Three Gorges Dam slightly lengthened Earth's days by 0.06 microseconds due to changes in mass distribution from the dam's water storage.
The dam's operation yields energy equivalent to 15 nuclear reactors, contributing to energy needs.
On August 5 of the previous year, Earth experienced one of its shortest days, rotating 1.25 milliseconds faster, attributed to the Moon's influence.
