I’m pretty busy and don’t have time to write anything particularly profound about it (I’m about to get on a flight to the Great White North, where we may have a mini bloggerbash in Edmonton), but as I mentioned on The Space Show a couple hours ago, tomorrow will be the thirty-ninth anniversary of the Apollo 1 fire, in which Gus Grissom, Roger Chafee and Ed White were suffocated and burned. Saturday will be the twentieth anniversary of the loss of the Challenger. Here were my memories of that event from a post four years ago. Jim Oberg takes advantage of the anniversary to explode (so to speak) several myths about the disaster.

And of course, next week will be the third anniversary of Columbia’s breakup over Texas. I may have more to say on that when the date arrives.
