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.
 
"This is an exciting development," says solar physicist Lika Guhathakurta of 
NASA headquarters in Washington, DC. "The ionosphere is important to pilots, 
ham radio operators, earth scientists and even soldiers. Using this new 4D 
tool, they can monitor and study the ionosphere as if they're actually inside 
it."
