ORLANDO, Fla. — The U.S. Space Force is strengthening its partnership with Japan in a bid to counter China’s growing dominance in the space domain. The collaboration includes advancing shared capabilities in space object surveillance in order to track increasingly sophisticated Chinese satellites capable of dynamically altering their orbits. Speaking at the Spacepower Conference on

An atom interferometer can make ultra-precise measurements of gravity RAL Space/IQO Hannover Extremely cold atoms have been used to measure gravity more precisely than we thought possible, beating a limit that stems from quantum weirdness. Ultracold atoms are some of the most sensitive force sensors. They are useful for such work because at the coldest
