Today’s most accurate atomic clock would take around 30 billion years to lose even one second.

The toaster-sized device could help make human travel to Mars—and beyond—a reality.

NASA’s Deep Space Atomic Clock is working toward giving far-flung space explorers more autonomy when navigating. In a new paper published in the journal Nature, the mission reports progress in their work to improve the ability of space-based atomic clocks to measure time consistently over long periods. Known as stability, this feature also impacts the operation of GPS satellites that help people navigate on Earth, so this work also has the potential to increase the autonomy of next-generatio...
