This Tuesday, July 14, NASA's New Horizons mission will reach its destination, and we'll collectively get to see things no human has ever seen before — things that surely no human should ever get to see at all, considering Pluto is a Russia-sized lump of frozen rock looping an irregular orbit some three billion miles from the only place humans have ever lived. But somehow, one thing has led to another, and now we have a little metallic child noodling its way towards trans-Neptunian space and snapping pictures. It took nine and a half years to get there, traveling almost a million miles a day. To get a sense of that scale, I suggest you force yourself to spend six or seven minutes scrolling through If the Moon Were One Pixel.
