Here’s how our final #Tiangong1 prediction stacks up against the actual reentry data. We had an error of 14 minutes, which was well within our window of +/- 1.7 hours. Thanks for following along with us this past week.

[Jonathan McDowell @planet4589]

The predictions were actually pretty good

[Steve Isakowitz @SteveIsakowitz]

This has been quite the rollercoaster weekend. Very proud of my @AerospaceCorp team for all their hard work with #Tiangong1 tracking and predictions, and very grateful to our @AFSpace @18SPCS #JSFCC partners for supplying the data that made our work possible. https://t.co/bsjpOUGACT
