After about 02:00
in the Kinematic video SpaceX Delivers Critical Docking Adapter for NASA to the ISS the astronaut says:
You know the Space Shuttle’s been with us, it’s been the heart and soul of the human spaceflight program for about 30 years and you know, it’s a little sad to see it go away, but hopefully in the not too distant future you’re going to see a heavy lift vehicle manufactured by our commercial partners designed by NASA in partnership, and we’re going to go back to the Moon; back to Mars.
So the future is very bright.
Is it possible to identify the astronaut and the shuttle mission?
