On the demisability and survivability of modern spacecraft
On the demisability and survivability of modern spacecraft
In a period where the evolution of the space environment is causing increasing concerns for the future of space exploitation and sustainability, the design-for-demise philosophy has gained an increased interest. However, building a spacecraft such that most of it will demise through design-for-demise strategies may lead to designs that are more vulnerable to space debris impacts, thus compromising the reliability of the mission. Demisable designs will tend to favour lighter materials, thinner structures, and more exposed components, whereas survivability oriented designs will favour denser materials, thicker structures, and more protected components. Given the competing nature of the demisability and the survivability, we developed a multi-objective optimisation framework to evaluate the effect of preliminary design choices on the survivability and demisability of spacecraft components since the early stages of the mission design. Such method is applied to the representative test case of tank assemblies of Earth observation and remote sensing missions.

Abstract
In a period where the evolution of the space environment is causing increasing concerns for the future of space exploitation and sustainability, the design-for-demise philosophy has gained an increased interest. However, building a spacecraft such that most of it will demise through design-for-demise strategies may lead to designs that are more vulnerable to space debris impacts, thus compromising the reliability of the mission. Demisable designs will tend to favour lighter materials, thinner structures, and more exposed components, whereas survivability oriented designs will favour denser materials, thicker structures, and more protected components. Given the competing nature of the demisability and the survivability, we developed a multi-objective optimisation framework to evaluate the effect of preliminary design choices on the survivability and demisability of spacecraft components since the early stages of the mission design. Such method is applied to the representative test case of tank assemblies of Earth observation and remote sensing missions.
