Throughout history, it has been advantageous to be on the high ground above the battlefield. In Space Program and other research programs is to determine which activities in space can be applied to meet terrestrial military requirements and how the Army can take advantage of these capabilities to enhance its operational effectiveness. Significant Contribution c. Although the capabilities of unmanned spacecraft are critical, experience has shown that manned spacecraft have also made significant contributions to the United States' space knowledge and capabilities. In many ways, humans are more versatile than machines.
Unmanned satellites are machines which can accomplish tasks for which they are designed.
They are, however, not well suited for accomplishing additional new tasks. They can gather data or perform a multitude of other tasks, but only when humans have determined that the capability is necessary. If satellite designers are not aware of a particular phenomena or capability, they do not design a satellite to gather data on the phenomena or to accomplish that task. Humans can function well in spite of uncertainty, ambiguity, change, unexpected occurrences and incomplete information. They can think, interpret, reason, and adapt.
