Weighing 187 pounds, including its fourth stage and transition section, its objective was to test the performance of a scout vehicle and its guidance system and to investigate the nature and effects of space flight on micrometeoroids. Its payload was a 76 inches x 24-inch cylinder, almost covered by five types of micometeoroid impact detectors, two transmitters, solar cells and nickel cadmium batteries. Its orbit was lower than planned and the satellite re-entered on August 27,1961.
