On the 22nd of November 2016, ESAs AVUM upper stage that was used on the first qualification flight of the VEGA rocket, launched in 2012, underwent a destructive uncontrolled re-entry. This resulted in the creation of at least 2 fragmented tanks which impacted in South India. Finding such objects is rare: only 71 events (first one for ESA) of this kind are confirmed after 60 years of spaceflight and nearly 7000 re-entries. Having such objects in combination with detailed orbital observations close to the re-entry epoch opens the option of rebuilding the break-up sequence with predictive models.The first objective of this activity is to create a faithful numerically rebuild of the re-entry trajectory and break-up sequence of ESA’s AVUM VV01 (VEGA upper stage), which re-entered the atmosphere after four years in orbit. The availability of the numerical rebuild of the event leads to the second objective of the activity, which is to calibrate re-entry risk verification tools and procedures in light of the observational evidence, quantify the remaining uncertainties on the physics implemented in such simulation tools, and establish procedures for on-ground component testing with maximum flight representatives.
