China plans first commercial rocket company

9:13 am

The competition heats up: A Chinese company has announced plans to start a new commercial rocket company to compete for the burgeoning space launch market.

China Sanjiang Space Group Co. is preparing to enter the commercial-rocket business with a launch slated for 2017, Xinhua reported Tuesday, citing the company’s chief engineer Hu Shengyun. Some Internet companies have expressed interest in collaborating on commercial launches, Hu said.

The Kuaizhou-11, translated as “fast vessel,” rocket is being developed by the Fourth Academy of China Aerospace Science & Industry Corp., a major missile supplier to the People’s Liberation Army, according to China Daily.

There is not much information at the link. The rocket was first launched in 2013, but not much has been revealed about it since.

What next for the computer Go program?

9:07 am

Link here.

The software uses neural networks to learn from experience. For example, to train for its Go match the computer program studied 30 million Go board positions from human games, then played itself again and again to improve its skills.

DeepMind’s founder and chief executive Demis Hassabis mentioned the possibility of training a version of AlphaGo using self-play alone, omitting the knowledge from human-expert games, at a conference last month. The firm created a program that learned to play less complex arcade games in this manner in 2015. Without a head start, AlphaGo would probably take much longer to learn, says Bengio — and might never beat the best human. But it’s an important step, he says, because humans learn with such little guidance.

DeepMind, based in London, also plans to venture beyond games. In February the company founded DeepMind Health and launched a collaboration with the UK National Health Service: its algorithms could eventually be applied to clinical data to improve diagnoses or treatment plans. Such applications pose different challenges from games, says Oren Etzioni, chief executive of the non-profit Allen Institute for Artificial Intelligence in Seattle, Washington. “The universal thing about games is that you can collect an arbitrary amount of data,” he says — and that the program is constantly getting feedback on what’s a good or bad move by playing many games. But, in the messy real world, data — on rare diseases, say — might be scarcer, and even with common diseases, labelling the consequences of a decision as ‘good’ or ‘bad’ may not be straightforward.

Hassabis has said that DeepMind’s algorithms could give smartphone personal assistants a deeper understanding of users’ requests. And AI researchers see parallels between human dialogue and games: “Each person is making a play, and we have a sequence of turns, and each of us has an objective,” says Bengio. But they also caution that language and human interaction involve a lot more uncertainty.

Blue Origin engine testing update

9:33 am

The competition heats up: Jeff Bezos has released an update on Blue Origin’s test program of its BE-4 rocket engine, being built as a possible replacement for the Russian engines in the Atlas 5.

Bezos’s final comment kind of explains why Boeing has favored them over Aerojet Rocketdyne for this engine:

One of the many benefits of a privately funded engine development is that we can make and implement decisions quickly. Building these two new test cells is a $10 million commitment, and we as a team made the decision to move forward in 10 minutes. Less than three weeks later we were pouring the needed three-foot thick foundations. Private funding and rapid decision making are two of the reasons why the BE-4 is the fastest path to eliminate U.S. dependence on the Russian-made RD-180.

I imagine however a lot of Congressmen are upset by this. If they do it too cheaply or too quickly there will be far less opportunity to spend pork in their districts!

SpaceX estimates 30% price cut from reusable 1st stage

11:04 pm

The competition heats up: At a satellite conference on Wednesday SpaceX President Gwynne Shotwell estimated that they will be able to cut the price of launch to about $40 million, a 30% cut from their already low prices, once they can reliably begin reusing the first stages of the Falcon 9 rocket.

Given that SpaceX has no intention, for now, of recovering the second stage, she said a launch with a previously used first stage could be priced 30 percent less than the current Falcon 9 rockets.

SES of Luxembourg, SpaceX’s biggest backer among the large commercial satellite fleet operators, has said it wants to be the first customer to fly with a reused stage. But SES Chief Executive Karim Michel Sabbagh said here March 8 that SES wanted a 50 percent price cut, to around $30 million, in return for pioneering the reusable version.

Shotwell said it was too early to set precise prices for a reused Falcon 9, but that if the fuel on the first stage costs $1 million or less, and a reused first stage could be prepared for reflight for $3 million or so, a price reduction of 30 percent – to around $40 million – should be possible.

Shotwell also said they hope to launch 18 times this year, with the first Falcon Heavy launch now set for November. This is another two month delay from their previous announcement, which had said they were hoping to launch in September.

With only two launches so far this year, I must say I am skeptical they can achieve 16 more launches in the year’s remaining 9 months, a rate of about one almost every two weeks. They have never come close to this schedule, and though I believe they can eventually do so, I don’t think they can do it so quickly.

ULA’s parent companies express caution about Vulcan

10:52 pm

The competition heats up? The executives in charge of ULA’s parent companies, Boeing and Lockheed Martin, today expressed mixed support for the development of the Vulcan rocket, designed to replace the Atlas 5.

For more than a year, Boeing and Lockheed Martin have been investing in the rocket on a quarter-by-quarter basis and the ULA board leaders said this week that the practice would continue. “We have to be prudent, disciplined stewards of any kind of investment,” Ambrose [Lockheed Martin] said. “Vulcan would be like any other investment decision.”

In September 2015, ULA’s leaders said a ban by Congress on the Russian RD-180 rocket engine, which powers ULA’s Atlas 5 rocket, was a leading driver behind the measured investment in Vulcan. But that issue was temporarily resolved in December, when Sen. Richard Shelby (R-Ala.) used a must-pass spending bill to eliminate the engine restrictions that had become law just weeks earlier.

Now, Ambrose pointed to “uncertainties” with launch policy, while Cooning [Boeing] said disagreements between lawmakers and the Air Force on the best approach for ending RD-180 dependence have given them pause, further justifying a “cautious and conservative approach.”

In other words, now that the law requiring a quick replacement of the Russian engine has been repealed, these executives feel less compunction to build Vulcan, something I had sensed in December and had commented on. As a result, they are telling us, in their tangled corporate ways, that they are not going to invest much of their own money on Vulcan, unless the government forks up a lot of cash for them to proceed.

XCOR wins Vulcan engine design contract

10:05 am

The competition heats up: ULA has awarded XCOR a design contract for building an upper stage rocket engine for the Vulcan rocket.

This is good news for XCOR, though there is one important caveat: A close reading of the press release at the link shows that the contract does not guarantee that ULA will use this engine in Vulcan. XCOR must deliver, and ULA must be satisfied with what they produce.

Another Falcon Heavy customer switches to different rocket

2:15 am

The competition heats up: Afraid of more delays in SpaceX’s Falcon Heavy rocket, Inmarsat has booked a Russian Proton rocket for a 2017 commercial satellite launch.

London-based Inmarsat is the second Falcon Heavy commercial customer to have sought a Plan B given the continued uncertainties in the launch schedule of Falcon Heavy, whose inaugural flight has been repeatedly delayed. Carlsbad, California-based ViaSat Inc. in February moved its ViaSat-2 consumer broadband satellite from the Falcon Heavy to Europe’s Ariane 5 rocket for an April 2017 launch, securing what may be launch-service provider Arianespace’s last 2017 slot for a heavy satellite.

Jeff Bezos gives a tour of Blue Origin

8:56 am

The competition heats up: Jeff Bezos gave his first tour of Blue Origin’s facilities for eleven journalists on Tuesday.

The article is chock full of interesting details about the company’s plans. To me these details about their New Shepard test program are the most interesting:

“We’re going to fly it until we lose it,” he said. The plan is to test the spaceship many, many times without humans aboard. At some point, Blue Origin will run a test in which the crew capsule will have to blast itself clear from the propulsion module at maximum dynamic pressure – a scenario during which the propulsion module will almost certainly be destroyed.

Not to worry, though: More crew capsules and propulsion modules are already under construction at the factory. “By the time anybody gets on, I think you should be willing to bring your mom,” Bezos said.

They also hope that this test program will proceed to launching humans by 2017.

Second solo Ariane 5 launch in 2016

8:46 am

The competition heats up: In successfully placing a commercial communications satellite in orbit last night, Arianespace also did its second consecutive single satellite launch.

The Ariane 5 rocket is designed to carry two satellites, and normally does so in order to maximize its profit per launch. That they have done two straight commercial launches without a second satellite suggests to me that the competition from SpaceX is taking customers from them. The scheduling of the secondary payload usually suffers because priority is given to the primary satellite. Those customers thus might be switching to SpaceX in the hope they can gain better control over their own launch schedule, while also paying far less for their launch.

Then again, considering how unreliable SpaceX’s own launch schedule has been, it is unlikely these customers will have yet gained any scheduling advantages.

The Kingsmen – Louie Louie

6:01 pm

An evening pause: Normally I don’t post videos with no visuals, but for this I will make an exception. It is probably the first time anyone has ever done the hard work necessary to translate the mumblings of the singer to find out the lyrics of this pop tune. Before now, who knew?

Building a log cabin, alone

6:01 pm

An evening pause: This is the first part of a longer work. To quote the youtube webpage,

“Alone in the Wilderness” is the story of Dick Proenneke living in the Alaska wilderness. Dick filmed his adventures so he could show his relatives in the lower 48 states what life was like in Alaska, building his cabin, hunting for food and exploring the area. Bob Swerer has taken the best footage from Dick’s films and he has created 3 videos about Dick, “Alone in the Wilderness”, “Alaska, Silence and Solitude” and “The Frozen North”

I like this because it gives a good hint at what life was really like for the original mountain men who first explored the American west. They were resourceful, clever, strong-willed, and technologically very sophisticated. Dick Proenneke shows us how to do it again.

Hat tip Rocco.

India’s space agency ISRO gets a budget boost

9:37 pm

In its new budget approved by India’s government the country’s space agency ISRO was the only science agency to get a significant budget increase, approximately 7.3%.

In the short run this is good, as ISRO has been using its funds wisely and accomplishing a lot for a little, while trying to encourage private development in India’s aerospace industry. In the long run, however, this will not be good, as government agencies always grow more than they should while sucking the innovation and creativity from the private sector. This is what NASA did in the U.S.

Hopefully, India will see how things are changing in America with private enterprise reasserting itself after a half century of government stagnation in space development and copy what we are doing.

Brownshirts try to silence conservative speaker

11:48 am

The coming dark age: Ben Shapiro speaks at California State U, despite fascist mobs, violent threats, and an attempt by the college president to silence him.

Be sure to watch all three video clips at the first link above. One shows Shapiro speaking as the fire alarm goes off. The other two clips show the hostile mob outside. The contrast is striking. All the mob needs are pitchforks and torches to complete the picture.

That it was possible for the left to harness such a large mob so quickly in an effort to silence Shapiro’s dissent suggests strongly to me that we are heading for very bad times. In a few short years, the students in that mob, who far outnumber the peaceful students who came to listen to Shapiro, are going to have powerful jobs and influential positions. And these fascists are going to be eager to use that power to squelch their opponents.

Addendum: Be sure to read this comment at the link from someone who was there. It is really frightening. As she notes,

I know from this site and others that this is what goes on. But actually being there and being shoved and taunted and blocked from hearing a speaker … it’s just another dimension. You can’t believe the insanity. You can’t believe the completely undeserved sense of moral superiority coupled with the simmering threat of violence. Really, really disheartening. …

The Young Americans for Freedom gang are a brave, brave group. Just completely outnumbered. Talked with one of them from the Reagan Center and she’d met Professor Jacobson and Mrs. Jacobson when they were at the center last year.

Seeing that in person, I think we’ve passed the point of no return. It’s not something you fix. It’s a stain you can’t get out … a complete mess. You cannot reason with people who refuse to listen to reason. At one point, one of the protestors was telling the guy next to me that Ben Shapiro was a racist and a supremacist because he was an Orthodox Jew, and thus should not be allowed to speak.

Tolerance. Behold.

Iridium dumps Russia for SpaceX

10:14 pm

In the heat of competition: Because of Russian red tape Iridium has switched from a Russian rocket to SpaceX’s Falcon 9 for placing its first 10 next generation communications satellites in orbit this year.

I thought the Putin government’s consolidation of its entire aerospace industry into a single corporation was going to speed things up? Not. Then again, SpaceX might not be any better, considering the problems it continues to have meeting its launch schedule.

SpaceX scrubs Falcon 9 launch again

10:01 pm

Update: It appears that they called the launch because of winds, though it also appears that the lower oxidizer temperatures have also reduced their weather margins.

In the heat of competition: For the second day in a row SpaceX has canceled a commercial launch of its Falcon 9 rocket because they were unable to get the oxygen in its tanks as cold as required.

The denser propellant gives the rocket added thrust, contributing to what SpaceX says is a 33 percent overall increase in its performance compared to the previous version.

But during countdowns Wednesday and Thursday, SpaceX reported trouble keeping the “deeply cryogenic” propellant cold enough. Although Thursday’s launch window lasted 96 minutes, it turned out SpaceX really only had one opportunity during that window. If any problem arose, SpaceX said the liquid oxygen would have to be drained and re-loaded, a process that would take too long.

This problem is troubling, suggesting that there might be a more fundamental issue here than they are saying. First, there was the significant delay since the last launch of this upgraded fueling system in December, implying that the data from that launch required some reworking. Now, they have scrubbed two launches in a row because they couldn’t get the oxygen cold enough to properly fuel the rocket. I also wonder if they need to reach a colder temperature in order to get enough fuel loaded to get the satellite to its proper orbit.

I generally trust SpaceX’s engineers to address a problem and fix it. Right now, however, they are under the gun. They need to get this working and begin launching rockets on a more reliable schedule. They have a lot of customers waiting in line.

The moment Yeltsin became a capitalist

10:50 pm

In 1989 Boris Yeltsin, member of the Communist Party in the Soviet Union and leader of one of what could be considered the equivalent of one of its mid-western states, visited Texas and toured the Johnson Space Center as well as a typical American supermarket. It was the grocery store that impressed him, not America’s space program.

He was dazzled by the fact that grocery stores were everywhere, and that they even offered free samples. A year or so later, a biographer wrote that on the plane ride from Texas to Florida, Yelstin couldn’t get the vision of the endless food supply out of his mind, and lamented how different things were for his own countrymen. According to wikipedia, Leon Aron, quoting a Yeltsin associate, wrote in his biography, “Yeltsin, A Revolutionary Life” (St. Martin’s Press, 2000): “For a long time, on the plane to Miami, he sat motionless, his head in his hands. ‘What have they done to our poor people?’ he said after a long silence.” He added, “On his return to Moscow, Yeltsin would confess the pain he had felt after the Houston excursion: the ‘pain for all of us, for our country so rich, so talented and so exhausted by incessant experiments.’”

He wrote that Mr. Yeltsin added, “I think we have committed a crime against our people by making their standard of living so incomparably lower than that of the Americans.”

And then, in his own autobiography, Yeltsin wrote about the experience at the grocery store himself, which reshaped his entire view on communism, ultimately leading to his leaving the Communist party. “When I saw those shelves crammed with hundreds, thousands of cans, cartons and goods of every possible sort, for the first time I felt quite frankly sick with despair for the Soviet people,” Yeltsin wrote. “That such a potentially super-rich country as ours has been brought to a state of such poverty! It is terrible to think of it.”

In writing Leaving Earth, I read all these same sources and was struck as well by how much this moment influenced Yeltsin. Very clearly, what Yeltsin saw that day led him to abandon communism.

If only more Americans could experience the same contrast he did, that of the shortages and poverty of top-down, command economies like socialism and communism vs the wealth and vibrancy and freedom of capitalism. I suspect unfortunately they will have to turn the U.S. into a new Soviet Union before they will realize how bankrupt such systems are.

SpaceX launch scrubbed

5:02 pm

SpaceX today scrubbed its Falcon 9 launch of a commercial communications satellite about a half hour before launch time.

They have not revealed why they cancelled, though they report the rocket is in good condition and have rescheduled for the same 6:46 pm (Eastern) launch tomorrow.

Update: It appears they had not gotten the rocket’s liquid oxygen as cold as they want. The colder it is, the denser it is, and the more fuel they can pack into the tank.
