Right now, Pluto is about 25 pixels across in the New Horizons space probe’s long-range camera. In a week it’ll be 50 pixels across. A few days later it’ll be well to 100 … and then it’ll grow by the hour.

What will we see? I wrote about all this for my twice-monthly column for Sen.com. Go see! It’s subscription only, but c’mon. I’m worth it.
