Is that some kind of improved artificial voice they're using for the narration?

I'm going to say what I always say when this comes up. The space program has never been suspended. After Apollo, manned space missions hit an inevitable wall with the distances involved and the challenges of going further. We were supposed to have people on Mars by now, but that was never realistic. Now someone has proposed a mission to Mars with astronauts who do not return. That just sounds insane in my opinion. There will be suicides.

Meanwhile, unmanned space flight has shown us more of the Universe than most of us can comprehend.
