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.
