Manned spaceflight is a source of constant conflict in the space science community. Of NASA's 16 billion dollar budget, almost 2/3 goes to manned spaceflight as opposed to unmanned endeavors. Specifically, nearly 7 billion dollars a year goes directly to the shuttle, space station, and related space flight support operation alone. More is spent developing new technology for manned missions, a large percentage of which have never seen the light of day (I think the latest Crew Exploration Vehicle is now the third possible replacement for the shuttle program). However, when it comes to scientific return, i.e. actually increasing our knowledge of physics, geology, atmosphere, space, the solar system and the universe, the vast majority comes from the unmanned space program. This includes everything from weather satellites to the
Hubble and Spitzer Space Telescopes to the Galileo and Cassini probes to Jupiter and Saturn.
In terms of scientific return per dollar, there is really no comparison. Manned spaceflight is a waste of money. Arguments are often made that money spent in manned spaceflight spawns technological innovation. While I believe there is a lot of truth to this, there is no reason to believe we would get more useful future tech from a Mission to Mars done with men rather than one done with robots. In fact, intuitively you would probably expect the opposite.
Having said all that, I must confess to being an astronaut junkie. Space is indeed the final frontier, despite anything contrary you might hear from
James Cameron. In the short term there may be nothing to gain from sending men into space, but that doesn't mean it is not worth doing. Not everything needs to be justifiable in dollars and cents. And if landing a man on Mars gets people excited about science, that may well be worth the ticket and then some.
Somewhere between that visionary trip to Mars and a complete and utter sinkhole is the International Space Station (ISS). Originally conceived as a science station follow-up to
Skylab, the original idea (Freedom Station) died a quiet budgetary death in the mid-80s. Perversely the vehicle designed to transport men to the station, the Space Shuttle, soldiered on for another 2-3 decades, a magnificent monument to poorly thought out long-term NASA planning. After the fall of the Soviet Union, the idea was resurrected as an international effort. The thought was to split costs and produce a larger space station without the need for a large number of new technological innovations. Somehow it didn't quite work out that way: The final U.S. price tag for the station is going to end up around 50 billion dollars. This amount could also easily be quoted as 100 billion if you include all the shuttle flights and the original sunk in development costs from the first station.
The station should be completed in 2010, a solid 7-8 years behind schedule and missing a couple of its coolest (and therefore most expensive) modules: Centrifuge Accommodations Module (used to produce varying levels of artificial gravity) and the Alpha Magnetic Spectrometer (measuring cosmic rays). The present long term budget phases out funding for the station in 2016 in order to make room for a mission back to the moon. That's right: 25 years in the making and 12 years of assembly and we presently plan on abandoning it after only 6 years of full use. This sort of planning has brought a great deal of deserved criticism, including that of Bob Park (U. Maryland), whose summation of the present plan seems a bit on the nose:
NASA must complete the ISS so it can be dropped into the ocean on schedule in finished form.
Still, the news from space is not all bad. While the international nature of the program probably cost us money in the long run, it kept the station manned after the Columbia disaster and kept a lot of knowledgeable Russian rocket scientists employed not making Iranian ICBMs. While the science being done onboard may be poor, NASA is learning a great deal about assembling structures of this size in orbit around the Earth. The final assembled station will span nearly a football field and weigh 472 metric tons (nearly 7 shuttles worth). Any large future missions, like say a manned mission to Mars, will require large spacecraft assembled in orbit.

My favorite thing to do with the ISS is to follow its progress, bit by bit. You can see where
all the parts came from, or you can check out the
remaining erector set-like pieces. The next year should actually be a good one, with the addition of two major science modules: the Columbus European Lab Module and the Japanese Kibo Experiment Module. This is much more exciting than all the pieces of Truss that have been going up the past couple of years. The latest piece,
Harmony: Node 2, has just arrived.
At this point, I would say I know quite a bit about assembling large structures. While I certainly can't compete with the icy grips of space, the Valley has horrors of its own. Between the 101 and the 405, no one can hear you scream.
Just too noisy.
As I believe I may have mentioned before, along with all the construction/remodeling I have been painting my house. The original plan had called for me painting the inside of my house, while hiring some plucky professional types to paint the outside. Midway through the process certain economic realities began to sink in. Realities like total money available and debt-to-earnings ratios and other unpleasant things. More savings had to be found. Since most sections of the budget were bursting at the seams, one of the few places we could save substantial sums and not compromise our vision for the house was painting.
As you might suspect, being also the father of newborn twins this additional painting duty has put quite a strain on my free time. As in, until this painting is done, I have no free time. Strain it any more and I will have permanent life stretch marks. Still, I am beginning to see the end of the tunnel on this one, although it is still very far away. More of slightly lighter stretch of tunnel than an actual end, but it is still nice not to be continuing on down into the dark.

But as the song says, one can get by with a bit of help from your friends. Round one was my birthday, when we primed most of the inside of the house. Round two was a couple of weeks ago when Steve and Amy, clearly racked with guilt over missing my birthday paintapalooza, came by to help out. This time we assaulted the front of the house, priming it from head (roof) to toe (ground? brick face? damn this metaphorical language!). Here is Steve scrubbing a substantial layer of grime from my front porch. I am secretly taking this photo from my rooftop perch.

From this same bird's eye view I managed to surveil the other pair of friends that made it out this Saturday, Caer and Ollie. Instead of getting dirty like poor Steve (and Amy, not pictured), they watched the twins (and Kynan) from inside this pen. It can not be underestimated how valuable this is. Anybody can slap on paint, but watching crazy babies...

So in the end we managed to make the entire front of my house a uniform shade of primer white, looking like this photo, only with slightly less blue tape. This is more or less how Steve and Amy, who busted their butts on this, last saw the house. I wanted to jump right in the next day and paint the house the final color, but as I pondered the situation I could not avoid the fact that all the trim overhangs walls. If I painted the trim after the walls I would drip all over the new paint. So reluctantly I did the trim first. Of course, the trim is White so even after busting my ass for a day and a half doing two coats and craning to paint all the overhead, hard-to-reach spots from this distance it didn't look any different.

Speaking of white trim let me take this moment to point out what a tremendous super-pain-in-the-ass painting these old multi-pane windows is. Particular this beast, which has 24 frames. That is a lot of wire brushing, scraping, masking, priming, painting, and second coating. Altogether all the windows on the house front had 54 frames, which is seriously too many. Demand bigger window frames. Write your congressman.

Here I am at the end of that weekend with all priming and white trim done. Look carefully. Look past the paint bespattered exterior. Ignore the drippy hat and the filthy t-shirt. Look into the eyes. Do you see the grim satisfaction of a job well done? Or the empty eyes of man who has journeyed beyond the edge of sanity? Wait. Don't answer that.
Let's just move on.

So here it is after Candy and I finally managed to get the main color on. That's right, I now have a green house. It takes some getting used to after having a grey-blue house for so many years, but I now think it is actually fairly sweet.

Just don't look at the house from too large of an angle, as so far the only part done is the front. With all the other things I have to get done, it may actually be a while before I get to those sides. My apologies to the neighbors on either side who will have to endure my over-extension. I will make it up to them down the road with fried turkey. Or a sugar cup dispensor. Or something.

I try to keep the immortal words of Jack Nicholas in mind, "All Work and No Play Makes Jack a Dull Boy." I keep seeing twin little girls. Is that bad? Anyway, the girls finally turned 1 year old and had their first birthday gifts.

With the actual birthday (Oct. 18... yes, my blog is now so far behind that historians read it to find it how people actually lived way back when) landing on a Thursday, we were forced to have two days of festivities. Only fair, they being twins and all. On Thursday Daddy had to work (boo) but Mommy arranged her schedule so that she could stay home and take the girls out on an adventure to the Kidspace museum. Fortunately for Daddy, they saved gift openings until I got home.


In this series of photos Rylie is in the pink outfit with a mouse on the front, while Kayla is in the brown outfit with a cat upon her belly. The assignment is relatively random, although we do tend to put Rylie in pink outfits more often for color coding reasons. The fact that Kayla will occasionally pounch on her sister and shake her, toss her in the air, and hold her down by her tail is completely irrelevant.
The small "chunky" books were a big hit. So much so that we have to have monitored visitations to them now. Sadly, the book on kittens did not make it through the first week. Apprently the chunky books are a perfect size for the babies to apply some serious torque to the pages. With a careful weakening of the spine thanks to steady application of saliva, the girls were able to tear it apart. The other five "chunky"s are still in decent shape and remain popular, if only during visiting hours.

The babies seemed to enjoy presents a lot, mostly becasue they are given full permission to do their favorite thing: rip, rip, rip! We had to be constanlty vigilant for their second favorite activity, which would have been jamming the paper into their mouths.
And speaking of jam and mouth, I will leave you with this photo of Rylie truly savoring one of her birthday cards. This from my Aunt Margo (their Great Aunt Margo). The cards were nearly as much of a hit as the presents, but for similar reasons. Envelopes were made to be ripped.
