Back in our region of space-time, it was spotted re-entering off the coast of the Canaries (this is the upper stage re-entering and not the nominal first stage disposal mentioned in the video title/caption, which was further north, back uprange, and would have had more of a head-on/line-of-sight perspective to this observer than the video suggests, plus probably insufficient energy to put on this sort of display).
Probably burned through the entire propellant budget with that momentary unscheduled side mission to the vicinity of exoplanet WASP-189b.

Key observations at this point in the investigation:
- The data is indicating that from the beginning of the second stage first burn, a fuel filter within the fuel feedline had been dislodged from its normal position.
- Additional data shows that the fuel pump that is downstream of the filter operated at a degraded efficiency level, resulting in the Newton 4 engine being starved for fuel. Performing in this anomalous manner resulted in the engine operating at a significantly higher than rated engine temperature.
- Components downstream and in the vicinity of the abnormally hot engine eventually malfunctioned, causing the second stage thrust to terminate prematurely.
- The early thrust termination ended the mission, and the second stage and its payloads fell back to Earth, landing in the approved safety corridor in the Atlantic Ocean.
