The Scout i s a four-stage, solid fueled rocket under development to provide the United States with a small, r e - liable a n d flexible research vehicle for a variety o f space explorations tasks. Coupled with this launch will be a 94 pound payload, P-21, designed to explore the physical phenomena i n the upper ionosphere. Th e ionosphere i s a continuum of electrically charged, or ionized regions, beginning some 4 0 miles above t h e earth and extending several hundred miles out, gradually merging with outer space. LAUNCH WHICLE Scout i s t h e nation's first solid propellant rocket to place a payload i n orbit.

Scout i s designed to place a 150-pound satellite i n a 300-mile orbit or to send a 50-pound scientific package nearly 8,500 miles i n a probe shot. For re-entry tests, the rocket can subject a payload to conditions like those encountered by space vehicles returning to the earth's atmosphere. I n a ballistic tradectory, i t can provide almost two hours of weightlessness for 100-pound experiments.
