As an ISS partner agency, ESA is in close contact with the Russian and US authorities regarding the Progress M-27M / 59P mission situation. The comments below are provided by Dr Holger Krag, Head of ESA's Space Debris Office at ESOC, Darmstadt, Germany. The Space Debris Office coordinates ESA's research activities on space debris, coordinates such activities with national research efforts, and provides operational services.
The team at ESA's Space Debris Office are providing regular reentry estimates to ESA Member States based on analysis of radar tracking data provided by our US partners, enhanced with data from Germany's TIRA tracking radar (operated by Fraunhofer FHR).
As of Thursday morning, 7 May, we are forecasting an uncontrolled reentry by Progress M-27M any time between later in the evening today through to mid-day tomorrow, 8 May.
The current large uncertainty is due to the unpredictability of the drag forces working on the vessel, and is a standard feature of such predictions. Any reports claiming precise re-entry times and locations at this stage are speculative.
Note that the data do appear to indicate that the Progress vessel is experiencing a very fast rotation rate of around one revolution every 1.8 seconds.
