I see this in a slightly different way. I consider (mass)producing chips with billions of transistors, building 200 meter high skyscrapers and similar things as impressive achievements even though they are kind of routine at this point. But they are no longer doing something for the first time and I think doing something for the first time is an important part of what makes an impressive event a really outstanding one. And at least for me right now going to Mars seems not sufficiently different from going to the Moon to have the feel of a first but that is surly very subjective.
