摘要

The Micron Accuracy Deployment Experiments (MADE) facility will be an orbiting laboratory for engineering research on proecison deployable structures. Such technology is crucial to the depolyment of large science instruments such as the Space Interferometer Mission and the Next Generation space Telesope, as well as other spacecraft requiring large depolyed optics. For these missions, very lightweight instruments must be deolyed on orbit and their dimensional stability must be actively controlled to nanometers of resolution-a technology not yet demonstrated on any spacecraft. Data from ground tests of prototype precision deployable structures indicate that, not only is this leve of stability difficult to achieve on deployable structures in 1-g, but the groverning microdynamics should change substantially in 0-g. The MADE facility will provide a laboratory for investigating the effects of 0-g on the microdyanics of precision deployable structures, and for developing low-cost, reliable, precision deployable instruments. The MADE facility is currently under development for the Engineering Research and Technologh program at the NASA Johnson Space Center. This paper discusses the motivation, objectives, system configuration and science protocols for the MADE facility.
