The new clock’s frequency instability is less than 4×10-19. (Courtesy: J Pan) Physicists have transferred time and frequency information over a distance of more than 100 km in free space, far exceeding the previous record. The technique, which makes it possible to synchronize and monitor optical clocks in environments where optical-fibre-based connections are impractical, could

PARIS — An agreement among three European countries could help secure near-term funding for launch vehicle development but have a bigger effect in the long term on how future projects are financed. The governments of France, Germany and Italy announced Nov. 22 they signed an agreement on “the future of launcher exploitation in Europe” intended,

The satellite communications industry is on a mission to virtualize every possible piece of ground infrastructure to catch up with the age of cloud-based networks. Converting hardware into software installed and managed remotely via third-party data centers would give satellite operators more flexibility over their networks and speed up how quickly they can respond to

By examining how light interacts with the microspheres, Lucie Hüser and colleagues at the University of Kassel

Riding on the shoulders of the Apollo generation, the Artemis missions will pave the way for humans to return to the moon, begin human exploration of Mars, and someday for humanity to reach the edges of our solar system and beyond. While the exploration of deep space is critical to advancing our understanding of so many unanswered questions about
