 In late 1962, after Ranger 5 suffered another booster malfunction (albeit a minor one that ground controllers were able to work around), NASA convened a review board which undertook a wholesale reevaluation of the Atlas-Agena as a launch vehicle.The board found that quality control and checkout procedures were poor, and that this situation was exacerbated by the several dozen configurations of the booster, as each individual DoD and NASA program necessitated custom modifications to the Atlas and Agena, and the latter also differed in its Atlas and Thor variants.The board recommended improved quality control, better hardware, and also establishing one standardized launch vehicle for all space programs.
