Abstract : Some of the reasons and needs are discussed for functional and environmental testing of spacecraft. Great differences exist in requirements for wind-tunnel models and rocket-boosted models for research in the upper atmosphere and space. Reliability is of prime importance and a well planned test program is one of the tools for insuring this reliability. A complete test program falls into 3 categories. Development tests provide information and assistance to the designer. Prototype or qualification tests prove that the equipment as designed and built will withstand the environmental rigors anticipated. Flight acceptance tests insure that the flight equipment does not contain workmanship defects. some development tests in conjunction with project Echo are illustrated and described. Environmental conditions to be considered in planning qualification and flight acceptance test programs are discussed. Included are some specifications and descriptions of tests on the S-55 Micrometeoroid Satellite. (Author)
