I'm afraid I don't have anything new for the Challenger anniversary this year, as I'm frantically writing a new piece on the end of the space shuttle era and preparing to go to Florida for the last launch of Discovery. (People keep asking me, when I mention I'm going to a shuttle launch, "Oh, cool! Where?" I try not to sound sarcastic when I answer, "Um, Florida. Have you ever heard of Cape Canaveral?" (The Kennedy Space Center is not actually at Cape Canaveral, but that's what they call it in the movies, and it has a pleasing alliteration.) My point is, space shuttles have only ever been launched from one place).
Anyway. In lieu of a Challenger anniversary post of my own, I want to direct you to a wonderful review of The Time It Takes to Fall by Catherine Howard over at Catherine, Caffeinated. She is the author of a memoir about living in Orlando for a while a a child as a visitor from Ireland-- must have been an odd experience, and I can't wait to read the book. She also has rather addictive blog about writing. She knows a lot about self-publishing in the era of e-books, which is a topic that a lot of people talk about without knowing nearly as much as Catherine seems to. You should check it out.
