NASA's Neil Gehrels Swift Observatory will re-enter our atmosphere around 3:30AM Eastern time tomorrow, November 4, according to the US Armed Forces' predictions. The exact time could be different, as the prediction has an "uncertainty of 11 hours." But the 3,200-pound spacecraft is heading back to Earth for sure, 22 years after it launched and after the agency's attempt to save it failed.
