<John Glenn was getting prepared to go to orbit.

Of course, we haven't been back to the Moon nor on Mars.
Of course, we turn around our planet.
But:
Science has progressed thanks to unmanned satellites, probes or landers.
Tourism in space is an immediate prospect.
There are humans in space all the time.
We can, if we want, see every moonwalk minute through videos.
Yes, humans had stepped on the Moon! It did happen and nothing can take this away from us.
We can, ourselves, "travel into space" with better and better telescopes.
And, perhaps, a crisis should be salutary and force some positive changes, within the manned space program.
