One of the essential aspects of space debris mitigation is the performance of Post-Mission Disposal (PMD) once the mission of a space vehicle has concluded. The main goal of the PMD is to avoid the creation of further space debris, especially mitigating the risk for on-orbit collisions or explosions that would cause a fragmentation and potentially contribute to the collisional cascading effect known as the Kessler syndrome. This paper focuses on the rocket bodies launched since 2016 that were not compliant with the 25 years rule established by the IADC space debris mitigation guidelines. The cumulative collision probability of these rocket bodies since their launch until their re-entry was studied as a measure of the risk that they pose to the environment. Moreover, the most suitable disposal orbits for these objects in order to be compliant were studied, as well as the ∆v requirements to reach that orbit and the risk mitigation resulting from these manoeuvres. Furthermore, a specific stage was chosen for a more detailed study of its disposal. The reduction of risk achievable by different values of the ∆v used in the disposal was analysed. Additionally, the impact of the attitude of the stage by means of its cross-section was studied, showing how variations in this value can lead to very different values of the remaining lifetime as well as the cumulative collision probability. The results show an in-depth analysis of the disposal options of rocket stages, raising awareness of the large impact that this measure has on the collision probability of these objects while they are on orbit and therefore on their impact on the future evolution of the space debris environment.
