The launch cost of Japan’s H-IIA rocket

9:51 am

The competition heats up: Yesterday’s launch of Japan’s first commercial payload on its upgraded lower cost H-IIA rocket suggested that they are now a serious player in the competitive launch market. What the earlier articles didn’t tell me was the cost they charge to launch a payload on H-IIA.

This article today states that each launch costs 10 billion yen, which translates to about $80 million. That is about $10 million more than SpaceX charges for its Falcon 9, but is certainly cheaper than many other rocket companies. At this price they have a chance of grabbing some of the launch market, but to really compete they need to cut that cost even more, which the article suggests their next rocket will succeed in doing: “The government is developing a new core rocket named the H3, whose launches are expected to cost only about a half of the H2A.”

They do not say whether H3 will be reusable, but at $40 million per launch it will be the cheapest rocket on Earth. That it is government developed however makes me skeptical they will succeed. We shall see. What is clear, however, is that the competition is certainly encouraging the lowering of cost.

Japan launches its first commercial payload

8:58 am

The competition heats up: Using its H-IIA rocket, upgraded to lower cost, Japan launched its first commercial payload today, putting Canada’s Telestar 12V into geosynchronous orbit.

It is not clear if Japan’s government-run space program can compete. The rocket is built by Mitsubishi, but it appears owned and operated by JAXA, the equivalent of Japan’s NASA. It has also been a very expensive rocket to launch, as for much of its existence it has been like SLS, more dedicated to producing pork jobs than actually competing with other rocket companies. Whether they can upgrade it sufficiently to compete in price with other rockets is highly questionable.

Nonetheless, that Japan is trying to compete is good news. The more competition, the better. The effort alone will produce new ideas, which in turn can only help lower the cost to get into space, thus making it possible for more people to afford it.

XCOR founders step down

8:49 am

In the heat of competition: Three of XCOR’s founders are leaving the company, even as it struggles to finish its Lynx suborbital spacecraft.

XCOR Aerospace said in a statement that Jeff Greason and Dan DeLong, the chief technology officer and chief engineer of the company, respectively, were “stepping back” from those positions “to turn their attention to pursue other interests.” A third co-founder, Aleta Jackson, was not mentioned in the release but is also leaving the company.

I am saddened that these individuals will not be there should XCOR finally succeed in finishing Lynx and flying it. At the same time, the fact that they are leaving at this stage suggests strongly to me that Lynx is nowhere close to flying, and that the company bean-counters have realized this and have now been forced to take action.

As regular readers to BtB know, I have always been extremely skeptical of XCOR’s effort. I have always wanted them to succeed, but in casting a cold eye at their progress I have never had much confidence that they would. Today’s story sadly adds strength to my skepticism.

Blue Origin lands first stage rocket vertically

8:34 am

The competition heats up: Yesterday Jeff Bezos’s company Blue Origin did its second test flight of its New Shepard suborbital rocket and capsule, and successfully recovered the rocket’s first stage, landing the stage vertically using its rockets.

As Jeff Bezos wrote at the link:

Rockets have always been expendable. Not anymore. Now safely tucked away at our launch site in West Texas is the rarest of beasts, a used rocket.

This flight validates our vehicle architecture and design. Our unique ring fin shifted the center of pressure aft to help control reentry and descent; eight large drag brakes deployed and reduced the vehicle’s terminal speed to 387 mph; hydraulically actuated fins steered the vehicle through 119-mph high-altitude crosswinds to a location precisely aligned with and 5,000 feet above the landing pad; then the highly-throttleable BE-3 engine re-ignited to slow the booster as the landing gear deployed and the vehicle descended the last 100 feet at 4.4 mph to touchdown on the pad.

When you watch the video you’ll see that we took the liberty of engineering all the drama out of the landing.

I have posted video of the flight below the fold.

SpaceX has been attempting this with its orbital Falcon 9 rocket for the last two years. They have come very close, hitting their target and almost landing. They plan to try again in December. Blue Origin however has beaten them to it, even if they have done it with a suborbital rocket.This demonstrates unequivocally that the concept is sound and that a rocket’s first stage can be recovered. It also demonstrates that of all the rocket companies in the world, SpaceX and Blue Origin are in position to dominate for at least the next decade. I am very confident that SpaceX will succeed in its efforts to recover its first stage. I am also very confident that Blue Origin’s plans to upgrade New Shepard into an orbital rocket/capsule will proceed quickly.

In both cases, the companies will then move forward, capable of recovering and reusing significant parts of their rockets, thus making it possible to significantly lower the launch cost and thus charge their customers less. No one else is in this position, or even close to it. The launch market will belong to them.

Trump’s real weakness

10:22 am

While Donald Trump has remained the leader in every poll for president since he entered the campaign, it still remains to be seen whether Republican voters will give him the nod when actual voting begins in the primaries. I have tended to believe that they will not, and I base this on Trump’s essential lack of understanding of the small government principles of conservatism. Though it is very clear that Trump has rejected the left and the big government ideas of the Democratic Party, it is also clear that he really doesn’t really believe in small government either. This story quoting a Trump speech from yesterday illustrates this very well:

Speaking during a town hall meeting in Iowa Thursday, Republican front-runner Donald Trump told the crowd the way to make college affordable for students is “to start some governmental program. … Well the only way you can do it is you have to start some governmental program and you have governmental programs right now,” Trump told the crowd.

Click on the link to read the whole quote, which also illustrates the generally incoherent way in which Trump speaks. His incoherency however, is not what hurts him here, but his easy acceptance of the idea that government is the solution.

Don’t get me wrong. Trump is by far a better candidate than any of the Democratic Party options, and he would do a far better job then them as well. His business experience in the real world will make him a better president, and is also likely the reason he now generally favors conservative solutions. Nonetheless, when voting time comes I think the Republican voters are going to move away from him.

Vine to Wine

6:01 pm

An evening pause: Making wine, the modern way. It is interesting how many steps here are still done by hand when they clearly could be automated. I suspect that it doesn’t pay for this winery to upgrade to more sophisticated equipment because their overall output is relatively small and it is more efficient for these steps to still be done by hand.

ULA concedes GPS competition to SpaceX

8:47 am

The competition cools down: ULA has decided against bidding on a military GPS launch contract, leaving the field clear for SpaceX.

ULA, which for the past decade has launched nearly every U.S. national security satellite, said Nov. 16 it did not submit a bid to launch a GPS 3 satellite for the Air Force in 2018 in part because it does not expect to have an Atlas 5 rocket available for the mission. ULA has been pushing for relief from legislation Congress passed roughly a year ago requiring the Air Force to phase out its use of the Russian-made RD-180 engine that powers ULA’s workhorse Atlas 5 rocket.

This decision might be a lobbying effort by ULA to force Congress to give them additional waivers on using the Atlas 5 engine. Or it could be that they realize that they wouldn’t be able to match SpaceX’s price, and decided it was pointless wasting time and money putting together a bid. Either way, the decision suggests that ULA is definitely challenged in its competition with SpaceX, and until it gets a new lower cost rocket that is not dependent on Russian engines, its ability to compete in the launch market will be seriously hampered.

Copenhagen Phil – Ravel’s Bolero

An evening pause: You really can’t pick a better classical piece for a flash mob performance than Bolero. It builds bit by bit, allowing the performers to slowly gather as if by accident. I also noticed that they seemed to be really enjoying the casual dress nature of this performance, which occurred at Coperhagen Central Station on May 2, 2011..

Vizio smart televisions watch YOU

10:12 am

If you are going to buy a smart television, don’t buy one by Vizio, as they by default track your viewing and provide the information to advertisers.

The feature, “Smart Interactivity,” is already turned on as a default setting for millions of people who have purchased the device. Viewers are able to turn off the setting, that is, if they know it even exists. “Non-personal identifiable information may be shared with select partners… to permit these companies to make, for example, better-informed decisions regarding content production, programming and advertising,” Vizio said in a statement.

Vizio seems to be taking a new approach by tracking viewers by default, while competitors like San Jose-based Samsung or LG Electronics leave it to customers to turn the setting on. Vizio’s sharing with advertisers also reportedly lets them target devices like your phone, which other companies do not.

Somehow this seems to be a direct violation of privacy, which also might be quite illegal.

Bibles banned from school libraries in Tennessee

9:19 am

Fascists: Because of a complaint, a Tennessee school administrator has banned Gideon Bibles from providing free bibles to the school’s libraries.

Superintendent Jennifer Terry would not elaborate on the complaints made. In a statement to Channel 3 News, she said the school system will no longer allow any religious group or material to be distributed. “Bledsoe County Schools do not allow the distribution of religious materials from any religious groups. The distribution of religious materials in a public school is in violation of constitutional provisions and well established federal and state laws and precedence,” Jennifer Terry, Director of Schools in Bledsoe County

This is insane. The government is not establishing a state religion by accepting free bibles from private American citizens for its libraries. It is a library, where books are made available to read. If the school can get some of those books free they should take them. To suggest that a government-run library can’t contain any religious books is the height of stupidity.

The article suggests that the community plans to protest this at the next school board meeting. It will be interesting to see what happens.

Dubai to use jetpacks to fight fires

8:59 am

Buck Rogers lives! In order to better fight fires among its many high skyscrapers, Dubai officials have purchased 20 jetpacks for use by its firefighters.

Martin Jetpacks have been developed with first responder use in mind. They can be flown by a pilot or via remote control, take off and land vertically, operate in confined spaces (such as close to or between buildings or near trees) and carry commercial payloads of up to 120 kg (265 lb). This functionality means the Jetpacks can provide a variety of first response services. For example, they can be used for surveillance or observation (such as to determine the focus of a fire), transporting equipment to where it is required, rescuing individuals or deploying specialist teams.

Though it sounds cool, remotely controlled drones would make more sense for most of these tasks. The jetpacks might be useful for getting crews in and out of difficult high locations, as well as possibly rescuing trapped victims, but to make this practical will require significant training, something that I don’t see as realistic.

SpaceX successfully tests its Dragon capsule abort rocket thrusters

10:39 am

The competition heats up: SpaceX has successfully tested its abort rocket thrusters that will be used to speed a Dragon capsule away from any rocket during a failed launch.

Named SuperDracos, the engines are arranged in four pairs – SpaceX calls them ‘jetpacks’ – integrated around the outside of the Crew Dragon spacecraft. Firing all at once, the eight engines produce 120,000 pounds of thrust – enough power to accelerate a Crew Dragon from zero to 100 mph in 1.2 seconds. In the unlikely event of an emergency, that power means the ability to lift the crew a safe distance off the launch pad or far away from a booster failing on the way to orbit. That capability was demonstrated earlier this year in a pad abort test that confirmed the SuperDraco design in a flight-like condition.

A normal launch of the Crew Dragon atop a Falcon 9 rocket would not offer the SuperDracos anything to do during the mission since their only responsibility is to fire in an emergency to rescue the crew onboard. Eventually, SpaceX plans to use the SuperDracos in the place of a parachute during landing.

Congress revises law governing commercial space

10:32 am

The competition heats up? Congress this week passed a revision to the Commercial Space Act that they claimed will help encourage the growth of the new industry.

According to the Senate press release, the bill does the following:

  • Extend the liability waiver for private space launches until 2023
  • Extend ISS operations until 2024
  • Establishes a legal right for U.S. companies to mine resources in space
  • Demands a new more streamlined framework for the government’s regulation of the industry

The last item is probably mostly blather, since a close look at the bill itself [pdf] reveals that most of these demands are merely requirements that the executive branch write a report. The odious rules that will allow the federal government to regulate and restrict the industry all remain. And even though the bill makes a big deal about establishing these regulations in concert with the industry itself, that only means that today’s players can use the government to make it difficult for new players to get started.

The claim that the bill also establishes “a legal right to resources a U.S. citizen may recover in space consistent with current law and international obligations of the United States,” as noted in the Senate press release, is a very big overstatement. The bill’s wording does nothing to get the U.S. out of the UN’s Outer Space Treaty, which forbids any person or nation from claiming ownership of territory in space. All the bill does is express the desire that American citizens should have the right to own what they mine, while at the same time stating that these resources will be “obtained in accordance with applicable law, including the international obligations of the United States.’’ In other words, the Outer Space Treaty still applies, and you can’t own it.

For what it’s worth, the bill also renames the FAA’s space regulatory agency from “The Office of Space Commercialization” to “The Office of Space Commerce.”

All in all, the bill’s most important overall accomplishment is that it strongly emphasizes and encourages the development of a private space industry, and tries to focus the government’s regulatory efforts in that direction. This ain’t perfect, but it could be considered a step in the right direction.

One more thing to note: Senator Ted Cruz (R-Texas) appears to have been a major player in getting this bill written and passed.

Another new American rocket engine tested successfully

9:58 am

The competition heats up: Sierra Nevada has successfully tested a new rocket engine, dubbed Vortex, specifically designed to fulfill a wide range of uses. From the press release:

These tests demonstrate the ability to transition use of different propellant combinations in the same core rocket engine design with slight changes to accommodate a specific combination of fuel and oxidizer, including propane and kerosene fuels with nitrous oxide (laughing gas) and liquid oxygen oxidizers. This latest development offers customers a suite of engines scalable to higher thrust levels and customer-selected fuel combinations from a single core rocket engine design. ORBITEC’s patented vortex rocket engines utilize a unique swirling propellant flow to naturally cool the engine walls, allowing for the development and manufacture of simpler, low-cost, light-weight and more robust rocket engine systems.

What strikes me about this is that, until SpaceX built its Merlin engine in the mid-2000s, it had been decades since the American aerospace industry had developed a new rocket engine. After the development of the shuttle’s main engines in the late 1970s nothing new was created for the rest of the 20th century. Since Merlin, however, we have seen a string of new engines from several different companies, suggesting that the new renaissance I wrote about back in 2005 is on-going and accelerating.

Why cold fusion and NASA’s EM Drive are most likely frauds

7:55 am

Link here. The writer does a nice job of explaining why impossible engines that appear to defy basic laws of physics are almost certainly incapable of doing what they promise, and are likely frauds.

An extraordinary result has to come with extraordinary evidence. When someone claims they have come up with something that can do something that engineers have been unable to do for centuries — since the very beginnings of the Industrial Age — I get very very suspicious, especially when their evidence is scanty and their data is not open for study.

Yale students demand two administrators be fired for defending free speech

8:13 am

The coming dark age: Students at Yale University on Thursday demanded that two university administrators be fired because they refused to ban certain Halloween costumes that might offend some students.

On Thursday, the students surrounded Yale College Dean Jonathan Holloway—a black man—in an outdoor space and chided him for failing to take action against a fraternity that had allegedly prevented black women from attending its party. (It’s not at all clear the allegation is true, according to The Daily Beast)

After giving Holloway his comeuppance, they moved on to Nicholas Christakis, master of Silliman College. What was Christakis’s crime? His wife, an early childhood educator, had responded to a campus-wide email about offensive Halloween costumes by opining that it was inappropriate for the college to tell students how to dress.

There are videos also showing the students attacking Christakis. Watch them, and then weep for the fall of western civilization. Key quote, by one of the students:

It is not about creating an intellectual space! It is not! Do you understand that? It’s about creating a home here! You are not doing that. You’re going against that.

In other words, going to Yale is not about going to a place where intellectual ideas of all kinds can be expressed. You go to Yale to feel safe and unbothered.

An evening pause: Normally I do not post music videos where the singers are lip-syncing so that they can stage some clever visuals, as is done in this video. However, the singing is so good, and the singers and song is filled with such joy, that it is worth listening and watching regardless. A good way to end the week.

Crowded Mexico City and colonization of space

11:15 pm

This week Diane and I are in Mexico with friends doing some sightseeing. As is my habit, I can’t just enjoy the sights I have to ask a lot of questions while trying to get an impression of the place, its culture, its environment, its atmosphere, and its politics. Not surprisingly, the answers to some of those questions pointed me upward beyond the surface of the Earth. To understand why, read on.

Today we toured the inner parts of Mexico City, both on foot and by bus and subway (or the Metro as they call it here). I have spent considerable time in many of the world’s major cities, growing up in New York and visiting at length Moscow, Kiev, Prague, London, Chicago, Los Angeles and others. Mexico City has many of the same features you’d expect for this kind of big city, lots of people, lots of traffic, lots of buildings packed tight together, and lots of wealth and poverty sitting side-by-side.

Mexico City traffic

Mexico City however to me seemed to be most crowded and the most packed of any city I have ever visited or lived in. Its size and population probably rivals that of the entire New York metropolitan area, but somehow the traffic and crowds and architecture seemed more piled on top of each other with far less breathing room.

First was the traffic. Everywhere we went it was wall to wall vehicles. The major highways were never quiet, even at night. Nor could I see much difference between midday and rush hours. The picture on the right shows us heading from in from an outer neighborhood where we were staying to take the subway into the center of the city. Not only was it bumper-to-bumper, but if you look out in the distance the road is bumper-to-bumper as far as the eye can see. My host Alfonso added at one point that in order to avoid this traffic many people routinely leave for work before 5 am and come home after 8 pm. Schools have multiple shifts, including ones at night.

A side note: The tall rectangular structures in the foreground are not buildings. This is a work of art, five several hundred foot tall cinderblock structures supposedly forming a hand pointing up, with the thicker yellow tower in the front representing the thumb.

Tomato harvesting

6:01 pm

An evening pause: Another video suggested by Phill Oltmann illustrating how engineering has revolutionized the agricultural field. In this case its tomatoes, which I think illustrates quite well why mass produced tomatoes are simply not as good as vine grown tomatoes from your garden. Assuming the tomatoes in this video are not intended for canning, they have to be tough to withstand the harvesting process so that they remain whole for the fruit stand.

Update to commercial space law stalled in Senate

6:26 am

Surprise, surprise! It appears that several Senate Democrats and the trial lawyer organizations that back them are objecting to passage of an update to the 2004 Commercial Space Act that would extend the period that companies would be exempt from liability while they experiment with new spacecraft.

Some Democratic members of the House Science Committee opposed those provisions when the committee marked up a version of the bill in May. “This really is quite an indefensible provision,” said Rep. Donna Edwards (D-Md.) during discussion then regarding the federal jurisdiction clause of the House bill, arguing that the bill is “basically providing the launch industry with complete immunity from any civil action.”

The American Association for Justice, a legal organization formerly known as the Association of Trial Lawyers of America, also spoke out against those sections of the bill in May. “Industries that lobby for immunity from accountability might as well hang up a sign saying they don’t trust themselves to be safe,” Linda Lipsen, chief executive of the association, said in a May 13 statement.

I really hate saying “I told you so!” but more than a decade ago, when the 2004 Commercial Space Act was passed, I opposed it because it gave the federal government far too much regulatory control over this very new and very experimental industry. Many industry people attacked me for doing so, saying that they needed this regulatory framework to raise capital.

Now the industry finds those regulations burdensome and is trying to get them eased, or waived temporarily. Not unexpectedly, there are vested interests in and out of Congress who don’t want those regulations eased. So, instead of focusing their energies on developing new technologies, the industry must instead spend money on lobbying and political dealmaking, which might get them some of what they want but will certainly also come with some political price that will be even more burdensome.

Kingston Trio – They’re rioting in Africa

6:01 pm

An evening pause: The amazing thing about this song is that it was written in the 1960s and does a good job of describing the insanity today. In the 60s it was actually exaggerating the chaos a bit. Today, it probably understates it. The only thing about the song that I objected to then, and now, is its eventual pessimistic view of humanity. We ain’t perfect, but we ain’t all bad either. In fact, I think there is probably more good than evil in most of us. We just need to listen, think, and choose. Chaos happens when we don’t, and instead act like mindless instinct-driven animals.

Excommunication scene from Becket

6:01 pm

An evening pause: On the eve of this year’s election day, this scene from Becket (1964) expresses well what I wish the American voters would do to both the Democratic Party and the Republican leadership in Congress. They all need to go, for the health of the country and because of their repeated malfeasance in office.

History: CNBC, the tea party, and this week’s debate

12:38 pm

Link here. The essay is a fascinating look back at the factors that generated the tea party movement in 2009, centered greatly on a single commentary that took place on CNBC at the time. The essay then notes how NBC then revamped CNBC’s lineup, making it far more liberal and Democratic, which is why we had what we had at the Republican Presidential debate this past week.

It is very much worth a read, as it gives some very important background to these events. It also makes this point, which I think is quite significant:

[I]t was Cruz’s defense of the entire field, and of all conservatives, that was like a game changing pick six in football. The debate was instantly different. That was the match and the gasoline to another conservative explosion. I contend nothing will be the same in debates any time soon, or in any liberal media interviews for that matter – and this is critical. [emphasis in original]
