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.

First I read Leo McKinstry’s Boycott book, and loved it. Then I read his Spitfire book, and liked that a lot also. But while reading Spitfire, I thought to myself that what I would also like to read – would really like to read – would be a book by Leo McKinstry about the Avro Lancaster, the big four-engined bomber that inflicted most of the British bomber damage on the cities of Germany during the latter half of World War 2. The Lancaster was one of my favourites during my Airfix years. Seeing a real live Lancaster flying at Farnborough in the summer of 2010 made me even more curious about this famous airplane. The more I thought about it, the more I realised how ignorant of the Lancaster’s history I was. So when McKinstry obliged with Lancaster, I did not hesitate. I bought it, and devoured it.
Ever since doing that, I have been meaning to write about this book here, but I never got around to finishing what I started. So instead of trying to say everything I might want to say about this excellent book, I will instead now focus mostly on the most interesting thing among many interesting things that I learned from reading Lancaster. I will focus on what a very strange birth the Avro Lancaster had.
In the late 1930s, believing that bombers would always get through and that they therefore had to have lots of bombers or lose the war, British Air Officialdom had two ideas about how to build a bomber. They accordingly announced two specifications, which different potential bomber-makers were invited to meet with their designs. They wanted a two engined bomber, like those that the Germans bombed Britain with in 1940 but better, or like the Wellington but better. And they wanted a much bigger four engined bomber, such as the Germans never got around to building, and like … well, like the Avro Lancaster.
So, the Lancaster was Avro’s answer to the second requirement? Actually, no. Or, not at first. Britain ended up with three four-engine heavy bombers, the Short Stirling, the Handley Page Halifax, and the Lancaster. But strangely, by far the worst of these three, the Short Stirling, was the only one of the three that was all along intended to be a four-engine bomber. Both the Halifax and the Lancaster started out as answers to the two-engine specification rather than the four-engine one.
This strangeness was caused by Rolls Royce then being engaged in producing two engines, the Merlin and the Vulture. The Merlin was proving itself to be very good (arguably it became the greatest single piece of mechanical kit of the entire war), but the Vulture was only revealing itself to be terrible. The idea was that the Vulture would power the two-engined bombers. But, with the Vulture already looking so bad, Handley Page quickly got permission to change their Vulture-powered two-engine bomber into a Merlin powered four-engine bomber. They switched specifications, in other words.
Avro persisted with their two-engine design, the Manchester, and Air Officialdom, in addition to ordering lots of Halifaxes, also ordered two hundred Manchesters to be made, long before they could be sure that it was a good airplane. Soon, they upped the order to over a thousand. Despite the Manchester being, to put it mildly, unproven, Avro started manufacturing them.
But the Manchester was a clunker. It was slow. It couldn’t carry many bombs. It handled abominably. It was a death trap. The pilots hated it. Avro did everything they could to make the Manchester work, but it never did, not least because Rolls Royce were never able to make much of their Vulture. As the Merlin began to prove itself to be the Merlin, Rolls Royce understandably concentrated on that.
At which point, in 1940, Avro proposed the Halifax solution to the Manchester problem. Turn the Manchester from a Vulture-drive two-engine bomber into a Merlin-driven four-engine bomber. Avro dramatically illustrated this idea when they showed a model of a Manchester to a visiting party of Air Officialdom. Right in front of their little audience of grandees, they took off the Manchester’s wings and shoved on different and bigger wings with two more engines attached to them. That, said Avro, is what we should be building.
ARKYD is a crowd-funded space telescope. You can pay to take pictures with it. The funding goal is met but there are seven days remaining to pledge $200 in return for the right to take a sensible space telescope photo of your chosen space object. The satellite also has a screen on its side. For $25 you can have a picture of the satellite displaying a picture of your choice with the Earth in the background. What frivolous capitalist fun!
Edit: the company making this telescope want to do asteroid mining. They have been answering questions about this on Reddit.
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?
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.
After a decade in the making, cost over-runs to the tune of billions of euros, and delays of more than three years, the next generation of European military transport aircraft is finally poised for entry into service.
“Ryanair has been forced to apologise to Italians after a crew member on a flight to the southern city of Bari reportedly described it as the “the city of the mafia and St Nicholas” in an on-board announcement.”
I am off to San Francisco for a week’s business and some sightseeing next week. I am flying via Virgin, and the last time I did, the announcement about the destination was not quite so, er, interesting.

“The next four days were a period torn out of the world’s usual context, like a breathing spell with a sweep of clean air piercing mankind’s lethargic suffocation. For thirty years or longer, the newspapers had featured nothing but disasters, catastrophes, betrayals, the shrinking stature of men, the sordid mess of a collapsing civilisation; their voice had become a long, sustained whine, the megaphone of failure, like the sound of an oriental bazaar where leprous beggars, of spirit or matter, compete for attention by displaying their sores. Now, for once, the newspapers were announcing a human achievement, were reporting on a human triumph, were reminding us that man still exists and functions as a man.”

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.
