ACES PHARAO Clock Achieves Record Stability in Space Microgravity
Operating 400 kilometers above the Earth aboard the International Space Station, the atomic clock assembly ACES/PHARAO has achieved a relative stability of 10⁻¹⁶ in microgravity, redefining time measurement by eliminating the gravitational constraints that limit high-precision instruments on the ground. For decades, physicists have refined atomic clocks to extraordinary levels of precision by measuring the … Read more
