April 30, 2008: Today, NASA-funded researchers released to the general public a new "4D" live model of Earth's ionosphere. Without leaving home, anyone can fly through the layer of ionized gas that encircles Earth at the edge of space itself. All that's required is a connection to the Internet.
Ham radio operators know the ionosphere well. They can communicate over the horizon by bouncing their signals off of the ionosphere—or communicate not at all when a solar flare blasts the ionosphere with X-rays and triggers a radio blackout.
