An experiment that fires powerful radio waves into the sky has created a patch of ‘artificial ionosphere’, mimicking the uppermost portion of Earth’s atmosphere. The research has not only caused glowing dots to appear around these patches — it could also provide a new way to bounce radio signals around the globe.
The High Frequency Active Auroral Research Program (HAARP), near Gakona, Alaska, has spent nearly two decades using radio waves to probe Earth’s magnetic field and ionosphere.
Todd Pedersen, a research physicist at the US Air Force Research Laboratory in Massachusetts, who leads the team that ran the experiment at HAARP, says that “Instead of depending entirely on the natural ionosphere to redirect radio waves or shortwave broadcasts,we are now getting the capability that we can actually produce our own little ionosphere”.
