On 8 September 2024, the first of four Cluster satellites will return home and burn up in Earth’s atmosphere in an uncontrolled ‘targeted reentry’ over a remote area of the South Pacific Ocean.
In the nearly 70 years of spaceflight about 10 000 intact satellites and rocket bodies have reentered the atmosphere. Yet we still lack a clear view on what actually happens during a reentry.
An airborne observation experimentwillnow attempt to witness the ‘Salsa’ (Cluster 2) reentry. Scientists on board a small plane willtry to collect rare data on how and when a satellite breaks up, which can be used to make satellite reentries safer and more sustainable in the future.
