Long Duration Exposure Facility (LDEF) space optics handbook

The overall objective of this effort is to construct a top-level space optics handbook that provides design guidelines based upon data collected from the Long Duration Exposure Facility (LDEF) experiment. The content of the handbook would cover optical coatings, surfaces, fiber optics, and fabricating process for lenses, windows and mirrors that were used on LDEF. The goal of this program (and handbook) is to ensure that the space community can derive the maximum benefit from the LDEF experiment relative to future optics designs for space applications. The summary of this handbook is 'What did we learn from the LDEF experiment?'

Dimensional scaling for impact cratering and perforation

This report summarizes the development of two physics-based scaling laws for describing crater depths and diameters caused by normal incidence impacts into aluminum and TFE Teflon. The report then describes equations for perforations in aluminum and TFE Teflon for normal impacts. Lastly, this report also studies the effects of non-normal incidence on cratering and perforation.
