试图收集对大空间结构动力学和控制建模、设计和测试领域的研究人员有用的数据。重点是结构动力学及其与颤振分析等相关工程领域的关系，以及轨道高度大气密度预测中的问题。大空间结构控制面临的第一个挑战是设计固有频率高于几个主要结构频率的控制系统。建立一个足够精确的结构模型，植物激励和形状维护，被认为是额外的问题。
An attempt is made to gather data useful to investigators in the fields of large space structure dynamics and control modeling, design and testing. Attention is given to structural dynamics and its relationship to such allied engineering fields as flutter analysis, as well as to problems in the prediction of atmospheric density at orbital altitude. The first challenge posed by large space structure control is the design of control systems with natural frequencies above several major structural frequencies. The establishment of a sufficiently accurate structural model, plant excitation, and shape maintenance, are noted to be additional problems.
