New technology could use X-rays to transmit data at high rates over vast distances in outer space, as well as enable communications with hypersonic vehicles during re-entry, when radio communications are impossible, NASA scientists say.
The technology would combine multiple NASA projects currently in progress to demonstrate the feasibility of X-ray communications from outside the International Space Station.
The radio waves used by mobile phones, Wi-Fi and, of course, radios, are one kind of light. Other forms of light can carry data as well; for instance, fiber-optic telecommunications rely on pulses of visible and near-infrared light.
The effort to use another type of light, X-rays, for communication started with research on NASA’s proposed Black Hole Imager. That mission is designed to analyze the edges of the supermassive black holes that previous research suggested exist at the centers of most, if not all, large galaxies…… READ FULL ARTICLE
