Spacecraft and their payloads are required to meet a casualty risk threshold for uncontrolled re-entries. The requirements demand that consideration be paid to the whole spacecraft and payload in order to achieve an optimised mission that is not penalised, where possible, by the cost of performing a controlled entry. The demisability of the spacecraft bus has received significant attention in recent years, the demisability of payloads has received less focus.
