Demonstration of the PADRE spacecraft assessment mode. This analysis simulated the destructive re-entry of a 1000kg component-centric vehicle, modelled as a relatively simple structore comprising approximately 40 components. Re-entry is predicted from a circular sun-synchronous orbit of 130km altitude using SAMj. Uncertainties in the initial state vector, atmosphere density, material properties, drag and heating coefficients are considered. A standard Monte-Carlo of between 1000 simulations has been executed.
The following distributions include results for all components that demise, including those that demise as atomic components, part of a compound fragment
