Description
Summary:In 2015, ESA's “ESA Space Debris Mitigation Compliance Verification Guidelines” handbook was released, dealing with the practical aspects of how missions can demonstrate their compliance to, among others, the applicable maximum on-ground risk figures. Therefore, to provide algorithms and methods allowing spacecraft system designers and operators to prove the compliance of their spacecraft with the applicable regulations, ESA's Space Debris Office decided to carry out the upgrade of the “Debris Risk Assessment and Mitigation Analysis” (DRAMA) software suite implementing up-to-date methods as well as innovative and unique functionalities. The tools provided by DRAMA enable an assessment of mitigation strategies for the operational and disposal phases of a mission, including the risk posed due to mission's space debris and the effectiveness of an end-of-life strategy. Within this framework, DEIMOS Space is responsible for the SESAM (Spacecraft Entry Survival Analysis Module) module of DRAMA, being subcontractor of HTG under an ESA contract. •Upgraded SESAM module is half-way between object- and spacecraft- oriented tools.•New types of relationships for spacecraft modelling: “included in”, “connected to”.•'Voxelator' module to take into account shadowing effects between connected objects.•New ablation algorithms to cope with metals and CFRP-like materials.•New NASA's EVOLVE 4.0 model to cover the effect of explosion events.
