U.K.'s Ariel 4 (UK-4) satellite was successfully launched by NASA on Scout booster from WTR at 12:47 pm PST. Orbital parameters: apogee, 587 km (364.8 mi) ; perigee, 472 km (293.3 mi); period, 95.2 min; and inclination, 83°. Primary objective was to investigate interactions between electromagnetic waves, plasmas, and energetic particles in upper ionosphere.
