A differential equation expressing the time rate of change of the number of objects on orbit has been developed. This approach, referred to as the "particles-in-a-box" (PIB) model, allows for the examination of orbital debris sources and sinks in a f

The polarity of GaN epilayers grown by molecular beam epitaxy is controlled using Mg. This is achieved by exposing the surface to a Mg flux under growth interruption. Reflection high energy electron diffraction (RHEED) indicates the formation of Mg/s

Not all realms of observation require an 8-meter telescope. Some, such as space surveillance of asteroids and man-made satellites, are too important to ignore, yet obviously inappropriate to consign to the new generation of large telescopes. The Unit

This paper describes a concept for a space-based collision warning sensor experiment, the Debris Collision Warning Sensor (DCWS) experiment, in which the sensor will rely on passive sensing of debris in optical and IR passband. The DCWS experiment wi

A 1.6-meter diameter f/0.95 all-reflecting telescope was designed to observe orbital debris particles as small as 1 mm from the shuttle payload bay. The telescope was specified to have a flat focal surface without the imposition of refractive element

In this paper, mission orbit considerations are addressed for using the Space Shuttle as a telescope platform for observing man-made orbital debris. Computer modeling of various electrooptical systems predicts that such a space-borne system will be a
