Two-dimensional model of a slow-mode expansion fan at Io
We develop a 2-D model for the standing slow-mode expansion fan that is expected to exist downstream of the Jovian moon Io. The leading edge of the expansion fan makes an angle of 45° with theExpand

Benefits and risks of using electrodynamic tethers to de-orbit spacecraft
Abstract By using electrodynamic drag to greatly increase the orbital decay rate, an electrodynamic space tether can remove spent or dysfunctional spacecraft from low Earth orbit (LEO) rapidly andExpand

Are de-orbiting missions possible using electrodynamic tethers? Task review from the space debris perspective
Abstract Over 9000 satellites and other trackable objects are currently in orbit around the Earth, along with many smaller particles. As the low Earth orbit is not a limitless resource, some sort ofExpand

SOCIT4 collisional-breakup test data analysis: with shape and materials
Abstract In this paper we revisit the 1995 Kaman database of the SOCIT4 fragment characteristics with added analysis of a subset of the cataloged fragments from the test. This database was compiledExpand
