Results of the IAASS Re-Entry Analysis Test Campaign 2012
Abstract
The Fourth IAASS Launch and Re-entry Safety Workshop was held at the NASA Wallops Flight Facility in September 2012. This was a joint workshop of the two IAASS Technical Committees for Space Hazards and Launch Range Safety. Since the second workshop in 2010, re-entry analysis test campaigns became a regular activity of these workshops. The purpose of these test campaigns is to promote cooperation, collaboration, and data exchange between the operators and developers of re-entry analysis tools all around the world in order to achieve a common baseline for reliable on-ground risk prediction due to surviving fragments from re-entering spacecraft. Two test cases were selected for the IAASS Re-entry Analysis Test Campaign 2012: an artificial, simplified satellite (about 400 kg) and a Delta-II Second Stage (about 925 kg). The Delta-II case was a simulation of a historical re-entry event which occurred on January 22, 1997. Several fragments resulting from this re- entry event were recovered on US territory. This paper will summarize and discuss the re-entry analysis results of the Delta-II test case provided by the following tools: SCARAB, DEBRISK, SESAM, and ASTOS/DARS.
