Joseph Stromberg has written a great article on Vox explaining why we should all be really, really excited about NASA's New Horizons mission, which is giving us - for the first time in the history of mankind - a clear view of what the dwarf planet Pluto looks like.
The article is definitely worth reading, but to whet your appetite, some of the many excellent points he makes are the following: we've never really seen Pluto before; the mission is a staggering technological achievement; it reminds us how utterly vast space really is; it's the first time in a generation we're seeing a new (dwarf) planet; there won't be another mission like New Horizons for a long time; and...space isn't just "somewhere", it's where we all live, so of course we should be interested!
Most people think of space as some distant, irrelevant place — a setting for sci-fi movies and astronauts, but one that has nothing to do with our actual lives. Seen in this light, visiting a new dwarf planet isn't particularly meaningful or exciting. But this isn't the right way to see space at all. Space is where we live.
