"This mission is the most outstanding project in the history of scientific and technological cooperation between Argentina and the United States,"
That's why the acronym is SAC and not SSA (Satélite de Aplicaciones Científicas - Satellite for Scientific Applications). I think it's just another satellite... This was newsworthy in Argentina only because there are very few local satellites (I can only recall past iterations of SAC). Even the president talked about this, "it is a matter of great pride for our people" (elections are near - the uranium enrichment facility is timed for 2 weeks before the presidential election's second round). But generally anything built by INVAP is newsworthy in the country: they are the big guys in engineering so they get all the important government tasks like reactors, submarines, radars, etc.
The most exciting phrase to hear in science, the one that heralds new discoveries, is not "Eureka!" (I found it!) but "That's funny ..." -- Isaac Asimov
