NASA's Neil Gehrels Swift Observatory is gone. The gamma-ray burst hunter re-entered Earth's atmosphere on Wednesday 4 November over the North Sumatra region of Indonesia, almost 22 years after launch, and the US Space Force confirmed the fall at 7:39 am US Eastern time. That's 11:09 pm on 4 November in Adelaide.
