This paper examine two hypothetical scenarios of surviving orbital debris reentry and their environmental impact. The first scenario is the uncontrolled reentry of Progress MS resupply spacecraft with surviving debris falling in the shallow water on the Anaa atoll in the Tuamotu Islands, French Polynesia. The second scenario is the descent of Progress MS resupply spacecraft surviving debris on the sandy beach shore of the Raivavae one of the Austral Islands in French Polynesia.

The aim of this paper is to present the approach to identify orbital debris reentry hazards through six historical orbital debris reentry events in chronological order. The orbital debris reentry disaster events were chosen by the type of their impact on the ground. In chronological order, these reentry events are: suborbital reentry of navigational satellite Transit 5BN-3 SNAP-9A (radioactive contamination) 21 April,1964; reentry of non-operational spacecraft Cosmos 954 (radioactive contamination) 24 January, 1978; reentry of Skylab space station (debris impact) 11 July, 1979; reentry of Salyut 7 space station (debris impact) 7 February, 1991; SpaceX Crew Dragon trunk section reentry in Australia (debris impact) 9 July, 2022 and reentry of nickel-hydrogen batteries from the International Space Station (ISS) (debris impact) 8 March, 2024. Disaster happens when a hazard impacts vulnerable population or area and causes damage, causalities and disruption. This paper will present the hazards of orbital debris reentry and possible disasters that such an event can produce by examining the past events of interest through MIRCE Science philosophy approach.
