I can’t find it, but after New Horizons beamed back telemetry data post-flyby, to effectively indicate that it didn’t get destroyed by rocks etc during the flyby, Alan Stern came into the auditorium waving a small, hand-held American flag. It was very cool.
Here is a video of Alan Stern reviewing that moment - note at the 1:02 mark the American flags in the coffee cups. https://youtu.be/hi7Si4Ssos4
New Horizons may the the last, great moment of purely American pioneering space exploration.
I hope not.
He’s got a good head on his shoulders.
