Here’s an interesting story about plans to probe the edge of our solar system by Agence France-Presse.

Excerpt:

WASHINGTON — NASA on Sunday launched a probe into orbit high above earth to study the distant edge of the solar system where hot solar winds crash into the cold outer space.

The Interstellar Boundary Explorer (IBEX) was launched at 1745 GMT, according to images broadcast live by the US space agency.

The small probe was deployed on a Pegasus rocket which dropped from the bay doors of a Lockheed L-1011 jet flying at 12,000 meters (40,000 feet) over the southern Pacific Ocean near the Marshall Islands.

“The count went really smooth… and everything appears to be going well,” NASA assistant launch manager Omar Baez said shortly after the launch.
