The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

The tick of the world clock depends on hundreds of atomic oscillators positioned across the globe. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

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 ...

Since the beginning of the space program, astronauts have dealt with the realities of spaceflight from microgravity in weak muscles and space radiation, to sleep deprivation and disorientation. Both ...

It was 2:30 in the morning when astronautical engineer Todd Ely watched as a little atomic clock—the size of a four-slice toaster—was launched into space on a satellite attached to one of the most ...

A group of physicists has announced one of the highest performance atomic clocks ever made. The instrument is said to measure time so precisely that it will only lose one second every 300 billion ...

As the precision and portability of atomic clocks continue to improve, University of Delaware physicist Marianna Safronova and collaborators Yu-Dai Tsai of the University of California, Irvine, and ...
