SpaceX successfully launched their Falcon 9 rocket, carrying the Dragon spacecraft into orbit. With all due respect to Burt Rutan and the folks at Scaled Composites, this is a much more significant event, as putting a craft into orbit and successfully recovering it is a much more difficult task than a sub-orbital hop.
What is interesting to me is that the next flight is scheduled for 12 April 2011, which will be the fiftieth anniversary of the first manned flight and the thirtieth anniversary of the first flight of the space shuttle.
It's hard to believe that it's been thirty years for the shuttle. Many of my coworkers weren't even born when it first flew, yet for me it seems to be only a moment. What's even harder (and more painful) to believe is that it only took twenty years to go from Vostok 1 to Columbia, but that the last thirty years has taken us from Columbia to soon to be nothing at all.
The darkness of space is nothing more than the veil of willful ignorance. How many of today's engineers and scientists were inspired by watching those early launches? What will inspire the builders of the future?
For Elon Musk and his crew, I congratulate and thank you. In your honor, I think that I'll break open my copy of Heinlein's The Man Who Sold the Moon.
Godspeed, Falcon.

Tradition
I think that most sporting traditions are over-hyped. You hear all the time about how the rivalry between team X and team Y is one of the greatest in sports and then the teams switch conferences and it's no longer so important. Alternately, one team could go into the tank for a decade, which puts a damper on the enthusiasm. Finally, (and let's face it) sports is a business and business does what business must.
One of the few sporting traditions that I truly support is the Army-Navy football game. This isn't because of the great players or the quality of play; for the most part neither school attracts the best players and neither is likely to challenge for whatever passes as the national championship. Nor is it because of the importance of the game; nothing of any real meaning will be decided on the field.
Instead, it is a great tradition precisely because it is a trivial event. When the United States is at war, many of the young men on the field will face opponents for whom the stakes are literally life and death very soon. They will have the opportunity to make critical decisions that could alter the fate of nations and they will be commanding dozens and then hundreds of other young men and women. But for one day each winter, all of this lies far ahead of them and all that matters for the hundred or so men on each team and the few thousand of their fellows in the stands is winning a football game.
How could any sporting event have a greater tradition than that?

It's a Good Time to Be a Space Cadet
As long as your horizon extends farther than manned missions, it's a pretty good time to be a fan of the space sciences. There are a number of terrific space probes out and about in the solar system (and even slightly beyond). It's truly incredible to go outside on a dark night and imagine that we've got little robots whizzing around visiting some of the neighbors.
My favorite active spacecraft are:
Opportunity and Spirit
Until NASA calls it for Spirit, I'm sticking with her. In the cosmic scheme of bang for the buck, these two little girls have definitely reset the bar. I have friends who joke that I can't go to the restroom without having an adventure, but Opportunity is the queen of the pop-up adventure. She's found so many meteoroids just lying on the surface of Mars that it seems as though someone held a galactic rock concert and she's the clean-up crew.
Dawn
Dawn is going to orbit the asteroid Vesta and then she'll wander off and orbit Ceres. How cool is that? It's moderately neato to actually visit an asteroid, but hopping between the (dwarf) planets is what the future was supposed to be about. Of course, doing it with an electric engine is so 21st Century, too.
Voyagers 1 and 2
The ultimate Energizer bunnies. The first man-made objects to leave the solar system. They're out there in the great beyond now. One neat thing about the Voyager Interstellar Mission is that they are calling home with 23-Watt radios. This is less power than a standard marine-band VHF radio.
