Friday is the 38th anniversary of humanity's first expedition to the lunar surface. Check out Rand Simberg's ceremonial commemoration of that epic event.

Friday is also the fourth anniversary ('blogiversary') of the launch of this humble blog. Here is the inaugural post (Note that I was too inexperienced to think of giving it a title.) on Life at the Frontier.
