Falcon 9 moving along

McGregor, TX (July 29, 2009) – Space Exploration Technologies (SpaceX) announces the successful completion of qualification testing for the Falcon 9 launch vehicle first stage tank and interstage. Testing took place at SpaceX’s Texas Test Site, a 300 acre structural and propulsion testing facility, located just outside of Waco, Texas. [First stage is green; interstage is black; this is the bird that will service the International Space Station when the shuttles are retired.]

UPDATE: But I’m opposed to government handouts for these and other commercial ops. We can see how well that worked for NASA, whose proposed Ares 1–whose capsule spacecraft is a throwback to Apollo and doesn’t even have an airlock–already is seeking more tax billions.

The Disagreement

The beginnings of Winder Hospital, which became one of Richmond’s largest in the Civil War, where my great grandfather, a private in Barksdale’s Mississippi Brigade, spent several months in 1862.

The post title, however, is that of this historical novel I recently finished about the training and coming-of-age of a young Virginia doctor during the war. Not at Winder, but at Charlottesville General Hospital on the UVA campus. A good story worth your time only if you are captivated by the period. The hero’s stuffed-shirt personality and the author’s extensive use of the vernacular can be annoying. The hero’s clinical detachment serves him well as a doctor but can make him a tiresome human being. Such jarring notes as his disinterest in religion are more modern than nineteenth century.

Now and then I felt trapped in some period memoir, becoming confused by the use of passive voice and multiple parentheticals. One detail, a slouch cap, was silly. A slouch was a hat, not a cap. Nevertheless, I found it hard to put down for long. I did miss the bleeding and cupping, two common treatments of the time to relieve fevers which were later discarded as doing only harm. I suppose the hero would have looked pretty stupid using either one and so they were left out.

The author obviously put a great deal of work into the tale (recounted in the back pages aknowledging his grants) and so I felt a little guilty at being able to acquire it almost new for one penny plus four dollars shipping. He can thank Amazon for that. One does wonder how the classical writers ever did it, without masters degrees in fine arts, writing workshops and multiple grants.

Falcon 9: It is Rocket Science

The first launch of SpaceX’s heavy lift vehicle, Falcon 9, may be delayed until fall, but its Falcon 1’s orbiting of a Malaysian sat ten days ago was a plus. Fun to have their Merlin engine test facilities just up the road in McGregor, southwest of Waco.

Might not be if they were rattling our windows, but they don’t do tests very often. Since their founder Elon Musk is the co-founder of PayPal, I hope my use of that service helps SpaceX, too. Falcon 9 was designed from the start to fly a four-man crew and service the International Space Station once the shuttles are retired.

Good luck, guys. It might not be in your plans but I hope you can beat the Indians and Chinese to the moon.

WD-40

Ever wonder what the household elixir’s name stood for? “…water displacement, formulation successful in 40th attempt.” I find it usually removes gum from hair on the first attempt, not to mention crayons from wood floors and freeing stuck sliding glass doors.

Via Althouse.

We’re Martians, after all

It’s nice to see new, if indirect, support for the Martian microbes announced in 1996. Makes sense to me. Still lacking, though, is an explanation of where the microbes came from before they got to Mars?

Starfarers

This was my first Poul Anderson epic novel and it’s a dandy. I see why he’s one of scifi’s revered masters. As previously mentioned about some other such books, the Amazon reader-critics are pretty harsh, for such reasons as it being hard to keep the saga’s many characters straight.

That’s inane. It’s easy to flip back a few pages to remind yourself, and the story is worth the effort. The tale’s overarching idea, that most of humanity eventually becomes bored with space travel and retreats to study itself, is a shocking thought. Then you remember how we landed on the moon on this very day and forty years later what do we do? Except for our robots (and their contribution, however limited, certainly is worthwhile) we’re not even exploring the solar system, let alone the stars.

UPDATE:  Indeed, fifty-one percent don’t even want to go to Mars. Sigh.

Noctilucent clouds

‘Tis the season. The luminous blue-white tendrils of cloud spreading across the high sky are back. Although not, probably, as far south as Texas.
