A broad survey of the literature detailing the state-of-the-art and future research trends in vibration isolation for current and proposed space systems is presented. Terminology for vibration control is first defined. Next, the vibration isolation problem is discussed taking into account nonlinearities associated with variable parameters. It is followed by a discussion of some current space specific applications, illustrating the tremendous importance of vibration control technology for space and the challenges these applications present. Next, a discussion of vibration control elements is provided. Finally, a summary of semi-active control strategies is presented and conclusions are drawn about the state of the art.

“…Option 2: The vibration isolation solution under the second option is based on Lockheed-Martin patented Disturbance Free Payload (DFP) architecture 22,23,24,25 . In that architecture (Figure 14), aside from electrical power and data cables bridging the interface, the instrument and the gimbal are mechanically isolated, thereby providing a high-degree of vibration attenuation.…”

Arcus: an ISS-attached high-resolution x-ray grating spectrometer

We present the design and scientific motivation for Arcus, an X-ray grating spectrometer mission to be deployed on the International Space Station. This mission will observe structure formation at and beyond the edges of clusters and galaxies, feedback from supermassive black holes, the structure of the interstellar medium and the formation and evolution of stars. The mission requirements will be R>2500 and >600 cm 2 of effective area at the crucial O VII and O VIII lines, values similar to the goals of the IXO X-ray Grating Spectrometer. The full bandpass will range from 8-52Å (0.25-1.5 keV), with an overall minimum resolution of 1300 and effective area >150 cm 2 . We will use the silicon pore optics developed at cosine Research and proposed for ESA's Athena mission, paired with off-plane gratings being developed at the University of Iowa and combined with MIT/Lincoln Labs CCDs. This mission achieves key science goals of the New Worlds, New Horizons Decadal survey while making effective use of the International Space Station (ISS).

“…Nelson and his group have made much effect in the mechanical design of noncontact spacecraft (see, e.g., [12][13]), and their work enhances the development of non-contact spacecrafts. However, the dynamical modeling and attitude control design problems are not discussed in their studies.…”
