Russia selling Sea Launch?

12:12 am

The competition heats up? Though he couldn’t reveal any details, the director of Russian space agency Roscosmos today said that they have found a buyer for Sea Launch.

“I cannot tell you who the investor is, or the value of the contract, due to certain obligations. I hope that we will have something to say about it by the end of April,” Komarov said. He did, however, say that investors from the U.S., Australia, China and Europe have expressed interest in the project.

Because Sea Launch is a floating launch platform, there really is no reason the company can’t be taken over by anyone in the world. And should the buyer use the Ukrainian Zenit rocket that the platform was designed to use, the technical problems might be reduced as well.

Using lasers to travel to the stars

9:44 am

The competition really heats up! A research team at the University of California, Santa Barbara (UCSB) has proposed that an array of space-based lasers can be used to accelerate a solar sail to speeds as much as 26% the speed of light, thus making interstellar travel possible.

[The] key breakthrough was the development of modular arrays of synchronized high-power lasers, fed by a common “seed laser.” The modularity removes the need for building powerful lasers as a single device, splitting them instead into manageable parts and powering the seed laser with relatively little energy. Lockheed Martin has recently exploited this advance to manufacture powerful new weapons for the US Army. In March last year, the aerospace and defense giant demonstrated a 30 kW laser weapon (and its devastating effect on a truck). By October, the laser’s power had already doubled to 60 kW and offered the option to reach 120 kW by linking two modules using off-the-shelf components.

The UCSB researchers refer to their own planned arrays as DE-STAR (Directed Energy System for Targeting of Asteroids and ExploRation), with a trailing number to denote their size. A DE-STAR-1 would be a square array 10 meters (33 ft) per side and about as powerful as Lockheed’s latest; at the other end of the spectrum, a DE-STAR-4 would be a 70 GW array covering a massive area of 100 square kilometers (39 square miles).

…Lubin stresses that even a relatively modest orbital array could offer interesting propulsion capabilities to CubeSats and nanosatellites headed beyond Earth orbit, and that useful initial tests would still be conducted on the ground first on one-meter (3-ft) arrays, gradually ramping up toward assembling small arrays in orbit. While even a small laser array could accelerate probes of all sizes, the larger 70-GW system would of course be the most powerful, capable of generating enough thrust to send a CubeSat probe to Mars in eight hours – or a much larger 10,000-kg (22,000-lb) craft to the same destination in a single month, down from a typical six to eight.

Further upgrades would make it possible to send a cubesate and its lightsail to Alpha Centuri in about fifteen years.

The important point here is that it appears that all the technology for building this already exists, or is relatively straightforward to develop.

Federal law outlaws launches on foreign rockets

5:37 pm

Killing competition: The American launch industry as well as the FAA regulators are in agreement that a 2005 law that limits American small satellite companies from using foreign launch companies should remain in place.

The CSLA, dating from 2005, is the U.S. government’s way of protecting the seemingly forever-nascent U.S. small-satellite launch industry from competing with government-controlled foreign launchers for U.S. business. It seeks to oblige non-U.S. rocket providers to sign a CSLA that, for all intents and purposes, sets U.S. commercial launch prices as the world minimum for government-owned non-U.S. launch providers.

The rationale is that these non-U.S. launchers, not bound by the constraints of profit and loss – but hungry for hard-currency export earnings – will undercut commercial U.S. companies’ launch prices and keep them from gaining market traction.

India’s launch rockets, for example, are designed and built by India’s space agency ISRO, and are backed not by private funds but by government money. The fear is that India could subsidize its rockets so that the price could always be kept below what any American company could charge.

The truth, however, is that competition and innovation, here in the U.S., has so successful undercut foreign prices that no amount of subsidies can hope to compete. Those foreign companies are now scrambling to actually redesign their rockets to lower their costs and thus their prices, rather than asking for more handouts from their governments. This law should be repealed.

More chalk oppression at Emory!

12:38 pm

Push back: A conservative student group at Emory University has responded to the protests against pro-Trump chalk messages on campus by drawing more pro-Trump messages.

Over the weekend, students involved in Emory’s Young Americans for Liberty chapter responded to the wailing and gnashing of teeth by the $59,444-per-year private school’s social justice warriors with a new, bigger, better political message in support of Trump, reports Inside Higher Ed. The newest chalking at Emory represents the Republican presidential front-runner in his trademark baseball cap. Scribbled on the cap is the slogan: “Make Emory Great Again.”

Young Americans for Liberty also chalked other messages on campus on behalf of every other remaining Republican and Democratic presidential candidate. Some of the other chalk imagery also managed to make clever use of the other candidates’ slogans. Leaders of the limited-government-focused group said their multi-candidate campus chalking adventure is manifestly not intended to endorse any particular candidate. Instead, the goal is to buck the growing national impression that Emory is full of ninnies who are afraid of temporary, mainstream political speech that can be instantly washed away with a bucket of water and a bit of scrubbing.

Good for them. They have more courage and common sense than the university’s idiot president, who had immediately agreed with the protesters that messages in favor of Trump had to be racist.

Emory University takes action to stop free speech

4:26 pm

The coming dark age: Students at Emory University are protesting the horror of having to see the words “Vote Trump” and “Trump 2016” written in chalk throughout the campus last week, and the university president, in total sympathy with these horrified students, has agreed to take quick action to prevent such horrors in the future.

The letter the university president wrote is worth reading in its entirety, as it illustrates forcefully the uselessness of today’s academic elite and the worthlessness of a liberal arts education at most of today’s colleges. Here is just one quote:

Yesterday I received a visit from 40 to 50 student protesters upset by the unexpected chalkings on campus sidewalks and some buildings yesterday morning, in this case referencing Donald Trump. The students shared with me their concern that these messages were meant to intimidate rather than merely to advocate for a particular candidate, having appeared outside of the context of a Georgia election or campus campaign activity. During our conversation, they voiced their genuine concern and pain in the face of this perceived intimidation.

After meeting with our students, I cannot dismiss their expression of feelings and concern as motivated only by political preference or over-sensitivity. Instead, the students with whom I spoke heard a message, not about political process or candidate choice, but instead about values regarding diversity and respect that clash with Emory’s own.

In other words, these poor students might have to admit that there is at least one person on their campus who disagrees with them and supports Donald Trump. We can’t have that! The president then goes on to outline some vague actions he is going to take to prevent such dissent from happening again. These students mustn’t be subjected to a free and open debate. It might cause them to think!

In related news, a Hispanic businesswoman who expressed Latino support for Donald Trump at one of his rallies is now being threatened and harassed at her business.

SpaceX sets date for next Dragon launch

8:41 am

The competition heats up: SpaceX has scheduled April 8 for the next Falcon 9 launch, set to carry its first Dragon capsule since the launch failure last year.

Though this is the most important news contained by the article, its focus is instead on the various preparations that SpaceX is doing at its Texas test facility to prepare for this launch as well as the increased launch rate required for the company to catch up on its schedule.

Note that the Dragon launch will also be significant in that it will be carrying Bigelow’s inflatable test module for ISS, built for only $17 million in less than 2 years. NASA, ESA, or JAXA would have required at least half a billion and several years to have accomplished the same.

South Korea commits almost a billion dollars to AI research

8:56 am

In reaction to the recent Go victory by a computer program over a human, the government of South Korea has quickly accelerated its plans to back research into the field of artificial intelligence with a commitment of $863 million and the establishment of public/private institute.

Scrambling to respond to the success of Google DeepMind’s world-beating Go program AlphaGo, South Korea announced on 17 March that it would invest $863 million (1 trillion won) in artificial-intelligence (AI) research over the next five years. It is not immediately clear whether the cash represents new funding, or had been previously allocated to AI efforts. But it does include the founding of a high-profile, public–private research centre with participation from several Korean conglomerates, including Samsung, LG Electronics and Hyundai Motor, as well as the technology firm Naver, based near Seoul.

The timing of the announcement indicates the impact in South Korea of AlphaGo, which two days earlier wrapped up a 4–1 victory over grandmaster Lee Sedol in an exhibition match in Seoul. The feat was hailed as a milestone for AI research. But it also shocked the Korean public, stoking widespread concern over the capabilities of AI, as well as a spate of newspaper headlines worrying that South Korea was falling behind in a crucial growth industry.

South Korean President Park Geun-hye has also announced the formation of a council that will provide recommendations to overhaul the nation’s research and development process to enhance productivity. In her 17 March speech, she emphasized that “artificial intelligence can be a blessing for human society” and called it “the fourth industrial revolution”. She added, “Above all, Korean society is ironically lucky, that thanks to the ‘AlphaGo shock’, we have learned the importance of AI before it is too late.”

Not surprisingly, some academics are complaining that the money is going to industry rather than the universities. For myself, I wonder if this crony capitalistic approach will produce any real development, or whether it will instead end up to be a pork-laden jobs program for South Korean politicians.

NOAA head poo-poos private weather companies

10:58 pm

At a congressional hearing on Wednesday the head of NOAA expressed serious doubts about the ability of private companies to provide worthwhile weather data.

At a hearing of the environment subcommittee of the House Science Committee on NOAA’s fiscal year 2017 budget request, NOAA Administrator Kathryn Sullivan said it was still too soon to determine if commercial sources of weather data, most notably GPS radio occultation systems, could augment or replace existing data sources. “In the weather domain, we believe it is a promising but still quite nascent prospect to actually have data flows from private sector satellites,” Sullivan said. “There have been a number of claims, there’s some hardware in orbit from at least one company that I’m aware of, but really nothing proven to the level that we require for ingesting something into the National Weather Service.”

This so much reminds me of past NASA administrators who repeatedly told us that private companies really couldn’t do the job of supplying ISS or launching humans into space, and that we really needed to leave that job to the government, which really knew better.

As it turns out, those past NASA administrators were wrong. Not only has private space done a very effective job at supplying ISS, they made it happen fast for relatively little money. And they are about to do the same in launching humans into space as well. NASA meanwhile has been twiddling its thumbs for decades in its efforts to replace the space shuttle while spending ungodly amounts of money and accomplishing little with it.

I have no doubt the same will be true with the weather. Allow private companies to compete for profits in providing the world with good weather data, and they will quickly do a far better job than NOAA. And the data will likely not be tampered with for political ends by global warming advocates in the government!

Self-tightening shoelaces!

9:05 am

Science marches on! Nike has unveiled its first pair of shoes that has automatically tightening shoelaces.

The Nike HyperAdapt 1.0 features a sensor inside that detects a heel sliding in, causing the shoe to automatically tighten around the foot. Two buttons on the side then allow the wearer to manually tighten and loosen the shoe until they have themselves a snug fit.

According to Nike, this ability to change tension on the fly solves what is apparently a “typical” problem for athletes: distraction. It does so by allowing precise adjustments to eliminate tight tying and the slippage that results from loose laces. It also imagines a future where a sports shoe can sense the moment you need a tighter fit for a quick mid-game maneuver and adjusts itself accordingly.

Virgin Galactic awards contract

8:58 am

The competition heats up: Virgin Galactic has awarded a contract to a Waco company to strengthen the wings of a 747 it intends to use the first stage for LauncherOne.

L-3’s work will make the left wing stout enough to support a rocket that would launch in flight from beneath the wing. This rocket would propel satellites into space for commercial and government customers. Company spokesman Lance Martin said that for confidentiality reasons he could not disclose the value of the contract or the length of the plane’s stay in Waco. He said performing work for Virgin Galactic and Branson should enhance L-3’s image, saying, “the customer speaks for itself.”

I suppose I should be excited by this, as it suggests that LauncherOne is moving forward. Considering Virgin Galactic’s history, however, I find myself sadly disinterested. I won’t get excited by this company again until they actually begin flying something.

ULA official resigns

8:48 am

In an update to the story last night about the head of ULA rejecting comments made by one of his chief engineers, that engineer has now resigned.

[Brett Tobey, formerly ULA vice president of engineering] resigned his position, effective immediately, ULA chief executive Tory Bruno said in a statement. ULA is a joint venture of Lockheed Martin Corp and Boeing. “The views, positions and inaccurate statements Mr. Tobey presented at his recent speaking engagement were not aligned with the direction of the company, my views, nor the views I expect from ULA leaders,” Bruno said in the statement.

In other words, we can’t have too much honesty here. There are games that Congress and ULA play with each other to justify the billions in subsidies the government gives ULA, and to note these games in a straightforward way is to note that the emperor has no clothes. We can’t have that.

I hope Tobey finds a job at SpaceX.

ULA head rejects his engineer’s remarks about Aerojet Rocketdyne

9:47 pm

The heat of competition: The head of ULA has disavowed his engineers’ remarks that plugged Blue Origin’s engine for the Atlas 5 while dissing Aeroject Rocketdyne’s.

The engineer was giving a talk at the University of Colorado this week where he made it pretty clear that ULA favors Blue Origin over Aerojet Rocketdyne, but had to make believe they were treating both companies equally in the competition to replace the Atlas 5’s Russian engines in order to keep the Air Force happy. Bruno is probably now doing some damage control, as the government still wants to justify the Aerojet Rocketdyne contract (whose only real purpose was as a government pork barrel jobs program). Considering all the money the Air Force and congressmen give to ULA, he has to keep them both happy. And telling the world that their Aerojet contract is a waste of government money is not a very good way to do this.

Nonetheless, he also admitted that Blue Origin is way ahead in development, and is thus most likely to win the competition anyway.

Tea party Republican wins primary for John Boehner’s seat

12:02 pm

A conservative tea party Republican has won the primary for former House Speaker John Boehner’s congressional seat.

If anything should tell the Republican leadership that they aren’t doing what the voters want, even more than the presidential campaign, it is this story. Boehner did nothing but show contempt for the tea party Freedom Caucus in the House, doing anything he could to block them. In the end, they were instrumental in getting him ousted. And as the article notes,

Davidson’s win Tuesday could give those [tea party] lawmakers reason to dig their heels in as things escalate. They can make their case to Republican leaders that, sure, putting their foot down on a proposed budget that increases spending might hinder Republicans’ goal of passing a budget on time. But what they’re doing is really in the interest of a growing number of Republican voters. Look no further than this highly symbolic seat they just won.

Even though I have serious doubts about Donald Trump’s conservatism, his rise is just another indication that the voters are pissed off at the leadership in Congress, from both parties. That leadership had better change its stripes soon, or it will find others taking their place, as has happened with John Boehner..

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.
