We are developing the social individualist meta-context for the future. From the very serious to the extremely frivolous... lets see what is on the mind of the Samizdata people.

A good article over at Reason by Ronald Bailey, the magazine’s science correspondent. He talks about the factors that explain why humans haven’t been back to the Moon since the early 1970s. It is, he says, because of a lack of profit.
Every time I write something about the incredible feat of putting someone on the Moon, as happened almost exactly 40 years ago, there is an inevitable chorus of criticism – much of it justified – about how the huge sums of taxpayers’ money involved rendered the project beyond the pale, even if the critics grudgingly accept what a great adventure the whole thing was. It has to be accepted that by “crowding out” private space initiatives in the way they did, government agencies both in the US, former USSR and elsewhere have arguably retarded more promising, long-term space ventures that might have got off the ground. The existence of large, politically directed agencies like Nasa do not help innovation, either. Consider how quickly the aircraft design process occured from the Wright Brothers and through to the jet age, and then compare the rate of progress of space flight over the past 40 years. It is not a flattering comparison. So this is precisely why Dale Amon is so right to comment on stuff like this.
The best way to honour the likes the astronauts, both the living, such as Buzz Aldrin, and the dead, such as Gus Grissom, is not to continue down the statist path of space flight. This is too important an issue to leave with bureaucrats.
SpaceX is scheduled for a launch today or tomorrow from their pad at Omelek Island in Kwajalein. The payload is RazakSat for the Malaysian government.
Most everyone in the commercial space business is wishing them good luck and hope the Falcon 1 flies well on its first ‘operational’ flight. I use quotes because it is still a new system and it takes time to really understand the foibles of that which you have wrought. Personally I would say their chances of a successful flight are excellent but not one hundred percent yet.
The big one for SpaceX will come with their first flight attempt for the Falcon 9 from Cape Canaveral. The rocket is on the pad and has been there for some months as they slowly work through all the issues preceding a launch of a big new rocket, probably later this year. This is the one which will eventually carry people in the SpaceX Dragon Capsule.
For now though, stay tuned. I will pass on information on tonight or tomorrow’s launch window as I hear it.
18:40 EDT: Launch appears to be currently schedule for 02:00 UTC/Zulu/GMT. Live feed for the Kwaj launch is available but is still showing dead air.
2230 EDT: Live coverage has begun. Watch here
2250 EDT: We are into a 15 minute weather hold at T-30 min.
2300 EDT: The woman doing some of the interviews is someone I know pretty well, Cassie Kloberdanz. She is a young member of the commercial space family and a lot of fun.
2316 EDT: As you can see if you are watching, the weather is starting to clear. I understand there was also some issue on the Helium pressurization which the hold gave them time to deal with.
2323 EDT: The clock is rolling again. We’re getting down to t-13.
2346 EDT: SpaceX has delivered its first international paying customer’s satellite to orbit! The flight was almost flowless as far as I could see from the video’s. Most notable to me was how ‘cool’ the expansion nozzle of the Kestrel second stage engine ran relative to previous flights. With two successes of Falcon 1 under their belts, SpaceX is now a competitor to be reckoned with.
So, what does this all mean? First, this was a key time for them. A launch failure would not have put their company at risk, but it would have had some serious repercussions on their future. The Augustine Commission is meeting right now and there is a political fight brewing in DC. There are some powerful congressman and constituencies that much prefer the status quo. The government backed Ares 1 project is, as one would expect, years behind schedule. The innovation of that particular camel is in the way they have taken bits and pieces of existing expensive hardware, manufactured for several decades in a number of key constituencies and managed to make a crewed vehicle out of it.
There is a small budget, relative to that of the big aero companies, that was set aside for new players. Those companies will be paid for a result: cargo on orbit at the Space Station. There are two currently: Orbital Sciences Corporation (run by David Thompson and friends) and by Elon Musk’s SpaceX.
This new way of doing business is something of a threat to the old one. The vehicles do not require huge numbers of people to process them. They are not as complex. They are designed with the idea that they will be commercially viable, and that means they cannot afford the baggage that every NASA designed ship has carried with it. Just as an example, the SpaceX rockets use the same fuel and oxidizer in both stages: Liquid Oxygen (LOX) and rocket grade Kerosene. Both are easily dealt with and familiar to industry. Notably they do not use Liquid Hydrogen (LH) for a higher energy, more ‘efficient engine’ because that efficiency comes at a high commercial cost. LH is squirrelly stuff. It will find ways to leak out if just about anything is not perfect. It is a ‘supercryogen’ and thus requires special materials and special handling. It is of very low density so it requires huge tankage to hold enough. By the time you are through, the margin gained in ISP (a measure of the efficiency of a rocket engine) is mostly eaten up by the extra structural mass. On top of that, the special requirements of dealing with LH are much more costly in terms of manpower, materials, care and testing.
But wait, there is more: The Ares I rocket uses the absolute worst feature of the Space Shuttle it replaces: a stack of solid rocket engine segments. You know, the ones with the famous O-rings? Once you light them you cannot shut them down or change the flight profile. However at least Ares I is a vertical stack so they could put an escape tower on the top to pull the astronauts away to safety if they find the thing is going to blow up or come apart or the RSO (Range Safety Officer) decides it really should be blown up before it hits Miami.
As bad as it is, Ares 1 had some major political clout behind it. Senator Richard Shelby from Alabama recently pulled funding that was to be used to do cargo delivery for hire and moved it to his district to feed the dinosaurs. A failure of this launch would have allowed these political types to say “See? We told you so! These commercial upstarts are not able to do the job. Rockets really are that expensive for a reason. That is why we need the money for our government designed rocket done by proper government contractors and with proper government design oversight… and built with parts made in our districts.”
Elon could probably get by without the space station delivery contracts, but they would certainly help. The problem for the American Rocket Design Bureau’s is that if he succeeds, he will change the game to one which is open ended and done with a wider commercial model in mind.
With this flawless launch under their belt, the case for commercial cargo delivery to orbit followed by commercial delivery of people becomes very hard to ignore.
0228 EDT: I heard a little while ago that the second burn of the upper stage was nominal as was the payload sep and the Malaysian customer satellite is in the correct orbit and is communicating with the ground.
I ran across this item in a Jane’s publication:
Boeing prepares X-51A for hypersonic test flight. The US Air Force ( USAF) plans to fly the Boeing Phantom Works X-51A Waverider hypersonic engine research vehicle at up to Mach 6 later this year. Joseph Vogel, Boeing X-51A programme manager, Advanced Network and Space Systems, and Charles Brink, X-51A programme manager, USAF Research Laboratory, spoke to reporters at Boeing’s Huntington Beach facility in southern California on 14 May.
For those who do not know of the Waverider idea, it is a technique for ‘surfing’ on the re-entry plasma. It could be an easier way forwards for getting back from orbit if it can be proven out.. The first I heard about it was roughly in 1985 when I met a Scotsman named Duncan Lunan at a the International Space Development Conference in Washington, DC. He showed up in his clan kilt at the celebration party of the Pittsburgh L5 team which I had led to victory in the competition to run the 1987 conference. Duncan paid his way over and back through the sale of a commemorative brew called “Halley’s Whiskey”, done by a Scottish whiskey maker for the 1986 return of Halley’s Comet. Duncan is without a doubt one of the more memorable characters I have met.
Duncan and his merry band of Glaswegians (ASTRA) ran a long campaign of low budget testing on the Waverider concept and managed to pool resources and get access to a wind tunnel as well as more eclectic test methods. I heard many of the results in the early 1990’s when he gave a talk at Queens University in Belfast for the local astronomy society lecture series. His talk was punctuated by the 6th floor windows rattling from a 1000 pound or so bomb going off at the police forensics lab a few kilometers distant. It was quite an introduction for someone who had never been to Belfast before… we in the audience were then of course discussing probable distances, type of explosive, size, and so forth. As you did when you lived in Belfast in those years.
I again ran into the ASTRA crowd at the WorldCon in Glasgow in 1996 I believe it was. I was there as a sponsor as I had provided the event with a free internet connection via my company in Belfast, Genesis Project Ltd. I believe we talked about Waverider then, but as I went bar hopping in Glasgow with one of the other team members and walked out of his high rise to greet the morning sun, I cannot say I remember much other than that Scotsmen drink like Irishmen.
In any case, I am glad to see this concept is finally getting some serious attention. It has, after all, only been around for three decades that I am aware of, and I would not be surprised if someone told me the idea was old even then. Although it could carry out the same sort of mission, it is not the same as the German Skip-Bomber concept which simply did the skipping stone thing off the upper atmosphere.
If anyone knows more about the X-51, feel free to drop by and comment.

Well, it is finally official. Astronaut Charles Bolden is the new NASA Administrator. If that were the only news then I would not be writing about it. What does interest me is that a woman who has worked towards this nearly her entire life has snatched the Deputy Director slot and I wish to publicly congratulate Lori Garver, a very old and dear friend on her success.
Ad Astra Lori!
PS: Now I have to find out what jobs George Whitesides and Alan Ladwig are getting. I have worked with George for the last 5 years and know Alan from back to the early eighties. I should be seeing them at the ISDC in Orlando in a couple days.
A US stealth aircraft, photographed while breaking the sound barrier. I don’t know why, given that Man has achieved the feat of breaking Mach 1 for more than half a century since the great Chuck Yeager officially did it first, but stuff like this still gives me a buzz.
Long time readers know I am part of the senior leadership team of the National Space Society and specifically the person charged with oversight of the conference which happens around this time each year.
We are going south to Orlando, Florida this year; the hotel is marvelous and the program likewise. Our Orlando conference management team and our HQ have brought together an excellent group of speakers. Most of the powers that be within the new commercial space industry and from NASA will be there. (Notice one dour visage within the photo gallery belongs to our own occasional writer, Taylor Dinerman. )
If you happen to be in that part of the country, or can arrange to do so, I highly recommend dropping in. You can register here.
I do not have time to be a speaker myself and will be racing from task to task, but if you spend some time in the hallways and corridors you are likely to see me transacting society and commercial space business in between board and committee meetings.
Be there, or be a groundlubber!
I would never have considered that the energy output of a TypeI Civilization could fit into my flat:
It is difficult, even for someone who has been working with these ideas and numbers for the past couple of decades, to get one’s head around the utter raw power potential of real nanotechnology. What Drexler is saying in this dry passage is that the amount of nanomotors needed to power a Kardasheff type I civilization, using all the sunlight that hits the Earth, would fit in a 500 square foot apartment (with 8-foot ceiling).
I might need a bit of air conditioning though…
I just picked this up form a Jane’s newsletter:
US announces successful tests of Airborne Laser
The US Missile Defense Agency (MDA) successfully fired multiple long-duration blasts of the Northrop Grumman high-energy Airborne Laser (ABL) during ground tests, the company announced on 19 February. The tests for the Boeing 747-400F-based ballistic missile defence system lasted up to three seconds each and were concluded on 12 February
This is good progress, but I am still waiting for the real test: shooting down an ICBM in flight.
Way back in 1994 or thereabouts I wrote in the Journal of the British Interplanetary Society about future applications of nanotechnology on spacecraft to get sensing in depth across all wavelengths in all directions at once. Well, it looks like we are getting there:
THE NEXT GENERATION.
Beyond the realm of CMOS and CCD image sensors, SiOnyx Inc. is developing a new material called “black silicon.” The company believes the material will lead to a new class of image sensors that are 100 times more sensitive than conventional silicon, detect energy from the ultraviolet to the short-wave infrared bands, operate at very low voltage levels, and can be made in extremely thin 0.5-µm forms (Fig. 5). Most importantly, the material is compatible with existing CMOS processing methods.
“This is a brand new material that is compatible with the largest manufacturing infrastructure of the world,” says Stephen Saylor, SiOnyx’s president and CEO.
I am guessing that ‘black silicon’ might be carbon nanotube technology or it might simply be an array that is so good at sucking up light that it appears black due to lack of wasted reflected photons. Whatever the case, I believe this is just the start of the sort of sensors I would like to see on spacecraft.
Taylor Dinerman attended a funeral of a respected soldier and space advocate and sent us this small remembrance of the man. I expect a couple of you in the commercial space business knew Mil Roberts from his days in High Frontier.
Taylor is a freelance professional journalist who from time to time graces our pages both on ‘page one’ and as a respected member of the commentariat.
“The flag that he honored with his life, now honors him.” These words spoken by the Army chaplain at the graveside ceremony for General Mil Roberts at Arlington on March 12th, explained why it is so symbolically important that the flag cover the coffins of our fallen heroes. The idea of reciprocal shared honor is one that binds any good military organization together, the past, the present and the future are all embodied in that symbol and with the deep meaning that we Americans give it.
The ceremony, with the honor guard, the riderless horse, a fifteen gun salute, the US Army Band playing Ruffles and Flourishes and America The Beautiful, the firing of the traditional three volleys, all done with precision and strict discipline but without the boot stomping and barked orders that one associates with some military ceremonies. The whole event was simple, elegant and dignified.
Mil was sent off to what he, as a Christian, believed was a better place by his friends, comrades and family in a style and manner that he had earned in combat and in years of service to America. He landed on Omaha Beach on June 6th 1944 and fought his way across Europe ending up in Czechoslovakia. Later he served in the Army reserves while pursuing a normal civilian life. In 1970 he was called up for active duty as head of the Army Reserve in the Pentagon.
As President of the High Frontier Missile Defense advocacy group, he helped get the DC-X program off the ground. That Rocket proved many things, including the fact that worthwhile space launch development programs could be done for far less than the billions of dollars that the government normally requires. This helped jump start the suborbital space tourism industry and may someday lead to a revolutionary low cost way to get into orbit.
Mil always had a great sense of humor and both he and his wife Priscilla had a wonderful gift for friendship.
He lived his life according to the old Jewish rule “Be a Mensch!”

While doing some research for other purposes I ran across this excellent video of a B-2 stalling and crashing on takeoff. If you have the vaguest interest in aviation I am sure you will find this as fascinating as I did.
All escaped unscathed except the USAF budget.
I am beginning to wonder whether the enemy outside or the enemy within is the more dangerous to our liberty. The al Qaeda can kill me… but DHS can enslave me. Here is the latest loathsome attack on private property and our rights as free citizens, courtesy of Downsize DC:
The same one-size-fits-all regulations will apply to both passenger airliners and non-commercial, business-owned jets that are used to move cargo and personnel. For instance, the “no-fly” list and Air Marshall provisions will apply to business planes even though the pilots usually know everyone on board personally. The definition of “large aircraft” is arbitrary, applying both to planes as small as 12,500 pounds and to 747’s ten times that weight. Items that are prohibited in passenger jets will also be banned to employees in these smaller business planes, even if they are needed for their work. (Just think of what that will do to business
efficiency in this time of recession.) Airplane owners will be forced to pay, at their own expense, for audits of their safety compliance. The audits won’t even be done by government inspectors, but by private consultants. These rules can potentially expand to all aircraft and all airports.
There is more here.
Crazed Islamic fundamentalists cannot destroy our country. No one in the world, nor any alliance of enemies or ‘friends’ can destroy the United States.
Only we can do that… and ‘we’ are racing to see how quickly we can snuff the light of Liberty.
