    MINNEAPOLIS, April 30 /PRNewswire/ -- ATK (NYSE:   ATK)(Alliant Techsystems)
 said nine of its solid propellant rocket motors helped successfully launch
 NASA's 2001 Mars Odyssey spacecraft toward the red planet from Cape Canaveral
 Air Station, Fla. earlier this month.

 mile journey to Mars on October 24, 2001, with the primary science mission
 taking place between January 2002 and July 2004.  The spacecraft's scientific
 instruments will tell NASA what the Martian surface is made of and record the
 planet's radiation environment to determine risks to future human exploration.

 II rockets include Mars Pathfinder, Mars Global Surveyor, and Mars Climate
 Orbiter.
     The Boeing Delta II motors are manufactured by ATK Aerospace Propulsion
 Company, Magna, Utah, which is part of ATK's Aerospace segment.  The segment
