Major space expeditions aren't really so common or insignificant that the "media" can just pick and choose which ones to report and which to dump.
What is it with this whole deal about the "media", anyway? Like there's one all-powerful news source that controls every information system in the country or something? There's no single coherent agenda, there's no organization or intelligence running even the greater majority of news services, they're just companies that report what's profitable, with some targeting niche markets like Democrats or Klansmen or what have you. Sometimes, this means toeing the government line, as said government is their main source of info, but other than that...
Yeah, yeah, I know most people are aware of that and just use the term out of laziness (myself included, when I'm not paying attention), but it's still wierd.
