The Defense Advanced Research Projects Agency (DARPA), the branch of the U.S. Department of Defense tasked with developing new technologies for the military, recently announced a new program called Atomic Clocks with Enhanced Stability (ACES). Atomic clocks are used to keep track of time in places where a tiny fraction of a second makes a huge difference.
