NASA's Orion spacecraft proves sound under pressure

(Phys.org) —After a month of being poked, prodded and pressurized in ways that mimicked the stresses of spaceflight, NASA's Orion crew module successfully passed its static loads tests on Wednesday.

Precise control of optical frequency on a chip

In the 1940s, researchers learned how to precisely control the frequency of microwaves, which enabled radio transmission to transition from relatively low-fidelity amplitude modulation (AM) to high-fidelity frequency modulation ...
