A couple weeks ago I had a several hour stop over in Las Vegas on the way from Chicago to LA. Las Vegas has never been one of my favorite places since I do all my gambling in real life and find little need for games of chance. However, this one sign may be enough to draw me back for a visit…
A very good reason to visit Las Vegas. (Copyright Dale Amon, All Rights Reserved)
I have long been following the slow movement of the new classes of weapons via which will one day arm Space Navies. The rail gun appears to be developing nicely and is a hypervelocity weapon, a very good replacement for explosives laden terminal defense, and perhaps even the venerable shipboard 5 inch gun.
US Navy funds Phase 2 railgun maturity effort
The US Navy’s Office of Naval Research (ONR) has awarded BAE Systems a USD34.5 million Phase 2 innovative naval prototype (INP) contract to advance the technology of the company’s electromagnetic (EM) railgun. “During phase 2, we are focusing our efforts on three things: maturing the system to allow for multishot capability, maturing the thermal management system [the higher rate shots that are fired, the better our system will need to be at cooling and prevention of overheating] and incorporating an auto-loading feature,” Dr Amir Chaboki, BAE Systems railgun programme manager, told IHS Jane’s
Perhaps one day we will have to modernize a famous US Navy quote: “Don’t fire until you see the sparks of their railguns!”

I had a rather enjoyable evening at the Lancaster Museum of Art and History last night. Quite an unusual event, although perhaps not so unusual for a community that hosts the Skunkworks, is not all that far from Edwards Air Force Base and NASA Dryden Research Facility… not to mention the Mojave Spaceport where there is a higher density of folks working in New Space than in any other spot on the planet.
So. What was so special? Perhaps the proverbial picture (of the main room of the Art Exhibit) is worth a thousand words.

Yep. There is a strong wing of the Art’s community that is excited about not just the concept of the adventure, but also the sheer beauty of the creations of engineers in the field. As major exhibitors, we were part of the after exhibit dinner in the museum and us rocket guys got on great with the artists. I found many of them think the ‘two cultures’ was a farce that needs to end. From my conversations I would say it was no accident some of the works refered to Leonardo da Vinci.
I also was quite surprised at one exhibit item that was a reproduction of the original. Gob-smacked might be a better word. It seems that a tiny art museum was smuggled on board Apollo 12. A tiny metal rectangle contained six even tinier works by 6 artists, among whom were Robert Rauschenberg and Andy Warhol. Yes folks, there is an original, albiet tiny, work by Andy Warhole still attached to an Apollo landing leg. On the Moon.
After dinner, the remaining crew, made up entirely of artists and rocket guys. Sort of. Even us rocket guys gave lie to the two cultures thesis. Doug Jones, a long time reader of Samizdata, was a stand up comic for awhile. As for myself I was in the music business professionally for many years.

After the entire group of artists and XCORians were filmed flying about the exhibit room pretending to be airplanes… yes artists have fun doing silly surreal things… we headed for Bex’s bar across the street where a marvelous time was had by all as we sat outside in a perfect desert evening talking art and space flight.
I also talked to one businessman who is a big arts supporter and a fed up Republican who has a solid dislike for the religious right. He asked a key question: How are Libertarians different from Conservatives? I think the illegal Edison Light Bulb went on over his head when I explained.
Naturally I was the last one of the crew to leave the bar. Those old music biz habits die hard.

How many here remember the discussions early in the previous decade about Admiral Poindexter and his Total Information Awareness concept? If one were to apply neural network techniques to VISA transactions, then a system might learn to identify subtle patterns that matched known terrorist events and might be usable to detect precursors to as yet unknown plots. The more data and the more different sources, the better the chance of training such networks to find patterns. Of course the numbers of false positives would be huge at first… and although it would go down over time, it would still remain fairly large as there is just too much noise in real world data and real terrorists would try to randomize their behavior after a few got caught.
I believe the concept is sound, the only problem is… it is utterly Orwellian. No, it is worse than Orwell imagined. It is the Holy Grail and wet dreams of the Checka, the KGB, the Stasi, the Gestapo and every other secret police system of the last century. The sad thing is that this has come to pass not in one of the many tyrannical states of the world… they are too incompentent to pull it off… but here, in our formerly free United States.
After much thought I have come to believe that Poindexter’s system was not rejected for funding and laughed out of congress as we thought at the time. That was nothing but a cover story as the whole thing slipped into the black world.
If this is TIA Black, we had better start challenging VISA, AMEX and all the others who process financial transactions. I predict that nearly every credit and debit card transaction in the US is being fed in along with the phone records and the google files and facebook pages and private email.
It is a virtual certainty. This isn’t 1984. It is much worse because as the techniques improve it becomes Skynet starring as Big Brother.
Planetary Resources is raising some of the money for a small space telescope via a Kickstarter and are close to their minimum goal of $1M. That such sums of money can be raised for worthy projects and in such short timescales strikes me as interesting in another way: might we be in the early days of a new way to deal with ‘the commons’? Could technology be delivering us a way to replace much of coercive government funding with true voluntarism?
And by the way, support these guys. I know several of them, and it is a way to push New Space forward in the public perception.
Sad to say, the thing about which I know the most is the one about which I can say nothing except point you to what is public domain. Here is the video which XCOR released after we got a 67 second burn out of our LOX/Kerosene engine. That was about the max we could go with the tankage we had for that test series. It is also the first dual reciprocating pump fed rocket engine ever fired. Can you say “reliable” and “low maintenance”? Stay tuned for further developments this summer.
Although I was on the test stand crew, I was not assigned to console duties in the test bunker that day. If you look closely in the background, you will see me with an idiotic grin developing as it becomes obvious we are going all the way with the burn. Had I not known I was on camera I would probably have given a rebel yell at shutdown.
Sometime in the next year four of those engines, in a non-teststand form, will give our pet astronaut a kick in the seat which will put a similar smile on his face.
Perhaps I should call this Part II since I recently posted my photos of the first flight of Richard Branson’s SpaceShipTwo: I was even thinking of doing a series to update our readers when I posted that article. Unfortunately the rest of the stories had to wait for these few mostly free hours on a late Sunday afternoon.
There are really big things brewing in the world of NewSpace. This is no long the realm of a bunch of cash starved spacers of the wild eyed variety. The recognition that just maybe they were wrong and we were right has got to be scaring the bejesus out of their financial offices. In some senses there is nothing new under the sun. It the same curve of accelerating technological change that overturned the IT business over 20 years ago. It has just taken a couple more decades to smash into the somewhat more difficult realms of aerospace.
For my first exhibit: SpaceX. By now most of you have heard of them. In about a decade, from a cold start, they have brought 3 different enginesl 2 different expendable launch vehiclel, a two way cargo capsule that is already passenger capable in an emergency; a large production facility in California, launch facilities at Kwajelein Island and at Spaceport Florida, and an engine test stand and test pad in Texas. They have booked enough business in the satellite market to put a serious bite into the competition. I believe three of those fully commercial, non-test flights will be happening this year with the first of them next month in June. In the Falcon 9 a rocket in the lift class needed for many commercial or government jobs, one which has proven operationally that where other vehicles fail, it just keeps going, a regular Duracell bunny of a rocket. Even an engine shutdown and a dynamic pressure caused collapse and spitting out of an engine bell does not slow it down. No one else can turn a launch vehicle around from an a pad abort where engines have fired… within an hour or two. No one. And to top it off they did the entirety of it for less total cost than the big aero guys are spending on their cost-plus throw away escape system.
And as the commercial says… wait, there’s more! They are in the process of certifying their own spaceport at Brownsville, Texas, where they will be having rockets not only launch… but come back and land when done. If you watch the Grasshopper flight below, bear in mind this is a 10 story building that climbs to 263 feet in the air, balances on a pillar of fire, then sets itself down exactly on the intended spot as soft as you please. I have had far rougher landing in commercial airplanes.
If all goes to plan, we can expect them to flight test these on the three upcoming commercial launches. After the booster separates it is scrap metal just waiting to meet its oceanic junk yard. Elon is going to wring the squeel out of that pig and it is going to fire its engine to attempt a controlled re-entry and it will be brought to a temporary hover some feet over the water. Maybe they will accomplish it on the first flight, maybe not for many flights. However many it takes, they will beat it and the cost of the tests will be a very small marginal cost since they would be dumping it in the water and it is already paid for anyway.
Once they have a handle on that procedure, they will fly it back to Brownsville and land it on a pad, just like in the test video. Then they will check it out, gas up the tanks and fly her again. They will next do something similar with the second stage. This will be a bit more difficult but at the end of their development program is a very big pot of gold. They will be many years ahead of all the competition, even national governments. They will have a fully reusuable, heavy lift, ‘man rated’ launch system that will drop the cost to orbit by anywhere from a factor of 10 to 100.
At that point the rest of the launch vehicle suppliers might as well pack up and go home. SpaceX is going to dominate the commercial launch market.
And then they are going to Mars. After all, you didn’t think Elon was doing this just for the money did you?
Taylor Dinerman, a long time member of the Samizdata Commentariat, who also on occasion writes for some minor paper called the Wall Street Journal, has just published a book of humor shorts written during his New York Subway travels. I suspect more than one of our regular readers will enjoy it… and besides which, he needs the money to pay for the subway tickets and bar tabs.
I have been a bit scarce around Samizdata lately as I have been out in the Mojave desert working on the Lynx Spaceplane… the same one you get to ride if you win the Lynx for Men contest. You know, the “Nothing Beats an Astronaut” one? In any case, we are not alone at the Spaceport. There are engine firings, vertical takeoff test flights by Masten Aerospace and yesterday… a milestone by our next door neighbours, Scaled Composites. I have very little time to write just now, but I do want to share a few of the images with you.
I got in by 6am and one of our guys was monitoring the tower frequency so we knew when they were cleared for takeoff.
We spent the next hour or so hanging out in the viewing area about a mile from our hangar. Most of the time we could not even find the little tiny spec in the sky.
My camera refused to focus on the tiny white dot of fire in the big blue sky so although I saw the drop and ignition visually, I did not get a picture. Their burn lasted in the range of 15 seconds and Doug Jones (XCOR) said he heard a mild boom so they may well have gone supersonic as planned. In this photo WhiteKnightTwo is diving to close on SpaceShipTwo, now on its glide to landing phase.
We were not all that far from the touchdown point on Runway 030. For those with long memories, Sir Richard Branson’s rollout bash on December 7, 2009 happened at the jet blast deflector at the threshold of 030. You can find that photo essay in the archives here.
I managed a number of good shots on the approach and was particularly happy to catch the very instant the wheels bit into the runway. Later on, outside our hangar, I spotted a grinning Richard Branson animatedly talking to designer Burt Rutan as they walked under WhiteKnightTwo on the way over to SpaceShipTwo. Yes, I do have those photos but I was on field outside our hangar so those photos will have to wait for posterity.
I understand some poor individual in Northern Africa recently posted a slur on Allah and did not delete it quickly enough… and for this a Saudi Mullah declared a death sentence upon him, a Fatwah. This got me to thinking… perhaps we have our own ways of laying curses upon the heads of such 10th Century fanatics. In fact, it might even be great fun and a marvellous creative exercise. So here is mine:
Oh ye purveyor of hatred, listen well as I lay a Western Curse upon you and your descendents unto the end of time: May your daughters abandon you. May they reject you and your foul beliefs and leave for the free world. May they make billions of dollars as free women citizens and marry whomever they wish and live in happiness the rest of their lives. May your sons run away and join the army and become great warriors who earn the highest honours and medals that Israel can bestow upon them. May your wife or wives found chapters of NOW and withhold sex from you until you treat them as equals. If you attempt to beat them, may they take out their Glock’s and shoot your worthless balls off. May you live to see all in the lands of the Middle East and Northern Africa living together in equality, peace and freedom.
Thus do I curse you and all who are like you.

Long time readers have no doubt wondered why I have become a scarce commodity on the pages of Samizdata; such readers also are aware of my long term connection with things spatial and free market.
For many years I have made some portion of my mostly meagre living in the Commercial Space arena. Staying in the game has been a costly proposition in terms of what I might have earned by simply forgetting the dream and just going for the gold. Those on the left seem to think that is what Libertarians do; but they are wrong. We are not about maximizing our wealth; we are about maximizing our liberty and doing what we want to do to the extent we can manage with our own resources. In my case, lacking much in the way of resource to begin with, that has meant surviving day to day on whatever short term contracts I could manage while I worked by myself or with others to gain a foothold in the then tiny NewSpace economy. I always thought it would be soon, really soon now… but this world for which I was born for took far longer than I had ever imagined to come to pass.
But it is finally happening and that is why there has been so little heard from me. I am now working under contract for XCOR, a number of whose members are long time Samzidata readers, out at the Mojave Spaceport in California. The future looks very bright for XCOR and many others in this industry. The big milestones are starting to get ticked off. SpaceX has had a stunning launch record and flew its Dragon to-be-manned reusable capsule in ProxOps [Proximity Operations] with the space station; Armadillo will probably bust the Von Karman line this year.
SpaceX is bending metal on the Falcon Heavy which will launch next year and will have the biggest lift capacity in the world. Of all the launchers that ever existed, only the Saturn V moon rocket was bigger. I suspect SpaceX will surpass even that before this decade is out. Bigelow has launch contracts in place and customers for his inflatable habitats that should be up around the mid-decade and will have a significant fraction of the capabilities and volume of the government owned space station. By the end of the decade or earlier in the next he will almost certainly have surpassed them.
By the end of this year or early next year the XCOR Lynx suborbital space plane will see air under its wings. As to when it will see vacuum under its tail, I could not tell you even if I knew for sure. It will happen when it happens and it will not be all that far in the future.
At first blush, Mojave is a speck in a vast desert, an old Western town that grew up into something not far removed from what you saw in old 1950′s SciFi movies. It is so much so I would not be at all surprised to find that the folks from 2 hours drive West in Hollywood did some of those movies here. At night when I drop into the local gas station, there is usually a Sheriff and several troopers hanging out talking with the woman who runs the store: just like it was in those old films.
No gunfighters, but it looks the part.

The current day town has three main industries. Wind farms and the railyards. If you are a train buff you would love the view from my motel as mile long freights go by just about every hour of the day.
The Samizdata people are a bunch of sinister and heavily armed globalist illuminati who seek to infect the entire world with the values of personal liberty and several property. Amongst our many crimes is a sense of humour and the intermittent use of British spelling.
We are also a varied group made up of social individualists, classical liberals, whigs, libertarians, extropians, futurists, ‘Porcupines’, Karl Popper fetishists, recovering neo-conservatives, crazed Ayn Rand worshipers, over-caffeinated Virginia Postrel devotees, witty Frédéric Bastiat wannabes, cypherpunks, minarchists, kritarchists and wild-eyed anarcho-capitalists from Britain, North America, Australia and Europe.
