SCOUT/REX LAUNCH SUCCESSFUL


   NASA's 114th Scout launch vehicle successfully placed an 
Air Force Radiation Experiment (REX) into a 450 nautical mile 
polar orbit over the weekend.  Liftoff occurred at 10 a.m. EDT 
on Sat., June 29, from Space Launch Complex 5 at Vandenberg 
Air Force Base, Calif.  

   Launch was originally scheduled for Friday, June 28, but 
was delayed 24-hours due to weather.  The 188-pound REX is 
managed by the Air Force Space Systems Division in Los 
Angeles.

   Launched by a Kennedy Space Center expendable vehicles 
team, Scout -- managed by NASA's Goddard Space Flight Center, 
Md.  -- has now performed flawlessly since 1975.
