US space agency will monitor the violence and turbulence at the edge of

The U.S. space agency launches a probe Sunday to monitor the violence
and turbulence at the very edge of the solar system. This artist
rendering released by NASA shows the Interstellar Boundary Explorer or
IBEX spacecraft in space, 19 Oct 2008NASA's Intersteller Boundary
Explorer is scheduled to begin its two-year mission at Kwajalein Atoll
in the Marshall Islands in the Pacific Ocean. NASA says the explorer
will orbit high above the Earth to take pictures of what scientists call
the interstellar boundary - an area billions of kilometers away where
hot solar winds crash into the cold gasses of outer space. Scientists
call the boundary regions vital to safe human space flight, saying they
shield the Earth's orbit from dangerous cosmic rays. NASA says the IBEX
images will allow scientists to understand the interaction between the
sun and the galaxy for the first time. Some information for this report
was provided by AFP.
