NASA's new breakup model of evolve 4.0
- N. Johnson, P. Krisko, J.-C. Liou, P. Anz-Meador
- Physics
- 2001
Abstract Analyses of the fragmentation (due to explosions and collisions) of spacecraft and rocket bodies in low Earth orbit (LEO) have been performed this year at NASA/JSC. The overall goals of this… Expand
LEGEND - a three-dimensional LEO-to-GEO debris evolutionary model
Abstract A new orbital debris evolutionary model is being developed by the NASA Orbital Debris Program Office at Johnson Space Center. LEGEND, a LEO-to-GEO Environment Debris model, is capable of… Expand
ORDEM 3.0 and MASTER-2009 modeled debris population comparison ☆
Abstract The latest versions of the two premier orbital debris engineering models, NASA׳s ORDEM 3.0 and ESA׳s MASTER-2009, have been publically released. Both models have gone through significant… Expand
Two-dimensional model of a slow-mode expansion fan at Io
- P. Krisko, T. W. Hill
- Physics
- 1 November 1991
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 the… Expand
Benefits and risks of using electrodynamic tethers to de-orbit spacecraft
- C. Pardini, Toshiya Hanada, P. Krisko
- Engineering, Physics
- 1 December 2006
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 and… Expand
Are de-orbiting missions possible using electrodynamic tethers? Task review from the space debris perspective
- C. Pardini, Toshiya Hanada, P. Krisko, L. Anselmo, H. Hirayama
- Physics, Engineering
- 1 December 2005
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 of… Expand

SOCIT4 collisional-breakup test data analysis: with shape and materials
- P. Krisko, M. Horstman, M. Fudge
- Physics, Engineering
- 2006
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 compiled… Expand
The new NASA orbital debris breakup model
- J. Liou, N. Johnson, P. Krisko, P. Anz-Meador
- Geology
- 2002
A new breakup model, including on-orbit explosions and collisions, has been developed andimplemented in the NASA orbital debris dynamical model EVOLVE 4.0. It is based on more than twenty… Expand
