An atomic clock that could transform deep-space travel has successfully completed its first test run in space.
NASA’s Deep Space Atomic Clock, which launched on a satellite in June 2019, outperformed all other clocks in space during its first year in orbit around Earth. The clock, DSAC for short, was at least 10 times more stable than clocks on GPS satellites, which makes it reliable enough for futuristic space navigation schemes, researchers report online June 30 in Nature.
