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
Today i’m bringing you an update on a very exciting qrp ham radio from Lab599. It’s called the Discovery TX-500. The TX500 is a HF & 6 meters 10 watt SDR radio, with a very rugged design. Lots of qrp operators are waiting pa... Read more
“Stacy Pharis, KI5MIT, has a homebrew antenna very similar in concept to the DX Commander, all held up by a tree. She wants to know if using a metal mast to hold it up would create issues. Yes, it would. Watch to find out why.” Read more
