Columbia Tragedy

My prayers and condolences to those seven astronauts that perished today. While we mourn their loss, we have to remember that few if any human advances came without risk (just think of the number of lives lost in the early days of the railways). The best way to honour them is to ensure that manned spaceflight continues and expands, and does not die with them.

An aside, it's probably a sign of the times that I first heard of this tragedy on from a blog, in my case Scott's.
