NASA-funded researchers have unveiled a new '4D' live model of Earth's ionosphere at the Space Weather Workshop, Boulder, CO. Without leaving home, anyone can fly through the dynamic layer of ionized gases that encircles Earth at edge of space itself. All that's required is a connection to the Internet. Airline flight controllers can use this tool to plan long-distance flights over the poles, saving money and time for flyers.
Using the Google Earth interface, users can fly above, around and through these regions getting a true 4D view of the situation. The fourth dimension is time. This is a real-time system updated every 10 minutes. Bright red is high density electrons; that's where radio communications are restricted to few or no frequencies. Blue is low density; no problem there.
