SOME FOLKS AT NSF sent this photo of the flag at half staff on the South Pole. Like space explorers, Antarctic explorers do something dangerous and important that a lot of people would like to do despite its dangers and discomforts.

Meanwhile, over at GlennReynolds.com, I’ve posted a bunch of reader email. It was foursquare in favor of doing more, not less, in space. Since I sent them that posting I’ve read hundreds more emails, and what’s posted is still representative.
