The weird practice that there be a different English word for every nation's astronauts just reflects the strange place the space program resides in: a political and cultural bauble, not an essential activity for the future of the human race. It's sad.
Sad, but not surprising. Look at how we, as a culture, have treated so-called "big science." As soon as the [elitist snob]unwashed masses[/es], and particularly politicians, think that Fermi, or our various other big research labs, can come up with a solution for something, or create a fancy new toy for the Pentagon, they're willing to invest, but only the minimum, and feel it their right to demand a solution ASAP. They fail, however, to understand that such research labs need funding of a significant amount for significant periods, and aren't really "quick-fix" institutions, but rather places to advance our broader scope of understanding of the Universe. I remember seeing a PBS special, "The Atom Smashers," that covered a period just before CERN opened their V.L.A, and how Fermi was striving to find the Higgs-Boson before such a heavyweight contender entered they playing field. Part of the film featured a public forum of sorts, to educate people on "big science" research, which from the looks of it was conducted at least in the 1980s, perhaps later. The people asking questions seemed to be utterly confused as to just what the scientists there did, and I got the impression of a distinct impatience that they weren't producing immediately viable results. The more the scientist conducting the Q&A session tried to answer and relate the relevance of their research, the more it just dissolved into contentious questioning of the worth of such research. As long as this anti-intellectual attitude remains the cultural norm, things like space travel and major physics labs, etc, will remain just as you said: a cultural bauble.
Wow, really did not mean to go on like that, but it needed to be said.
