Relative Dynamics and Control of an Ion Beam Shepherd Satellite

The ion beam shepherd (IBS) is a recently proposed concept for modifying the orbit and/or attitude of a generic orbiting body in a contactless manner, which makes it a candidate technology for active space debris removal. In this paper we deal with the problem of controlling the relative position of a shepherd satellite coorbiting at small separation distance with a target debris. After deriving the orbit relative motion equations including the effect of the ion beam perturbation we study the system stability and propose different control strategies.

The SIROCO Asteroid Deflection Demonstrator

There is evidence of past Near-Earth-Objects (NEOs) impacts on Earth and several studies indicating that even relatively small objects are capable of causing large local damage, either directly or in combination with other phenomena, e.g. tsunamis. This paper describes a space mission concept to demonstrate some of the key technologies to rendezvous with an asteroid and accurately measure its trajectory during and after a deflection maneuver. The mission, called SIROCO, makes use of the recently proposed ion beam shepherd (IBS) concept where a stream of accelerated plasma ions is directed against the surface of a small NEO resulting in a net transmitted deflection force. We show that by carefully selecting the target NEO a measurable deflection can be obtained in a few weeks of continuous thrust with a small spacecraft and state of the art electric propulsion hardware.

South Carolina’s Creative Cluster : A Catalyst for Economic Development

This report presents results from a study of the creative economy associated with the arts, design, crafts and related activities in South Carolina. As this report will show, these creative individuals and enterprises exert a strong impact on the state’s economic base. Like other drivers of the regional economy, this creative activity revolves around a cluster, or a set of interrelated industries, that thrive in tandem. Along with manufacturing and agriculture, the creative cluster is a catalyst for state and local economic development. The report presents results from an analysis of the South Carolina creative cluster based on 2008 data. For the first time, this report provides a comprehensive summary of the creative economic footprint in South Carolina.
