Proton failure investigation finds quality control the root problem
In the heat of competition: The Russian investigation into the most recent Proton rocket launch failure has now found that the cause of the turbo pump failure was because of significant management failures.
The investigation into the MexSat-1 failure established that a fast spinning shaft inside a turbine of the RD-0212 engine propelling the third stage can break easily due to excessive vibrations. (The turbine is designed to pump propellant into four thrusters which steer the rocket in flight.) Yet, despite the problem lingering in the engine’s design for decades, the fact that two of these three accidents had happened in the past 15 months was itself is not an accident!
In an interview with the Russian business web site BFM.ru, the head of Roskosmos Igor Komarov disclosed that due to recent easing of requirements for the quality of metal that had gone into the production of the shaft, the turbine became more vulnerable to vibrations. Additional fascinating details on the same issue had surfaced on the online forum of the Novosti Kosmonavtiki magazine.
As it turned out, dangerously low requirements for the turbine shaft were set in the design documentation during the development of the rocket. However the issue was identified early during testing and the production team self-imposed extra margins for the affected components to remedy the problem. However in 2013, the new management began questioning why so much manufactured parts had been disqualified during production, even when they had met lowest requirements set in the design documentation. By that time, the new generation of workers and mid-level production managers no longer saw a reason to fight for more stringent requirements, which were actually making their own work more difficult. As a result, the hardware which was barely making through the quality control was certified for the installation on the engine, thus giving the old design flaw more chances to surface. [emphasis mine]
The description above reminds me strongly of the circumstances that took place prior to the Challenger failure in 1986: Engineers trying to fix a problem that managers don’t want to see.

More problems at Virgin Galactic?
The story outlines what appear to significant problems at Virgin Galactic:
- Some sources say the company has shelved LauncherOne in favor of a bigger launcher that would be deployed from the bottom of a 747, not WhiteKnightTwo.
- The company however says LauncherOne is still under development.
- The company admits that they recently had a LauncherOne test rocket engine explode during testing.
It appears that they have discovered that LauncherOne is not cost effective for meeting their contract with OneWeb to launch 39 satellites. It would only be able put up one satellite at a time. A more powerful launcher however would be too heavy for WhiteKnightTwo.
Thus, after 10 years of development, nothing they have built to date is useful for a profitable operation, and they apparently have to start over.

Russians confirm their commitment to ISS through 2024
Even as a new crew arrived at ISS, the head of Roscosmos confirmed that the Russians are now committed to sticking with ISS through 2024, as requested by the U.S.
I’ll make a prediction: The station’s life will be extended beyond 2024, but not necessarily under the control of its present international partnership. If the governments involved consider backing out at that time, there will be private companies then capable of taking it over, and will demand that the U.S. transfer ownership to them. This will in turn act to pressure the governments to continue the station’s operation.
Either way, ISS will continue.
Meanwhile, quality control issues continue to pop up with the Russians. One of the solar panels on the Soyuz capsule that delivered crew to ISS yesterday had failed to open when commanded, then decided to pop open unannounced during the docking. They had enough power to get to the station with only one panel, and the panel opening at the wrong time fortunately did not cause any problems, but for the panel to open as it did is without doubt worrisome.

Hackers demonstrate they can remotely take over moving vehicle
Does this make you feel safer? In a demonstration of the vulnerability of modern cars that are linked to the internet, two hackers took over the operation of an unmodified moving Jeep Cherokee.
A pair of Missouri-based hackers have put on an extraordinary demonstration by logging into a Jeep Cherokee remotely, while it was being driven by a Wired reporter Andy Greenberg, and systematically taking over the car’s functionality. First, they hit him with cold air through the air-con system, then they blasted Kanye West through the stereo at full volume, rendering the volume knob completely useless. They flashed up a picture of themselves on the car’s console and set the windscreen wipers going full blast, squirting cleaning fluid onto the windscreen and making it difficult to see.
But these were just warmups to the main event – next, they took over the engine and shut it off completely, leaving the driver powerless and coasting on the freeway as traffic flashed past around him. Then, once he was off the highway, they showed how they could completely disable the brakes, and take over the steering of the car – only at slow speeds and in reverse, but they’re working on unlocking new abilities every day.
This suggests to me that linking any car directly to the internet is probably a very bad idea.

Falcon Heavy first test flight delayed again
In the heat of competition: The first test flight of SpaceX’s Falcon Heavy rocket has been pushed back from the end of this year until April 2016.
This isn’t surprising after the June 28 launch failure. They have to get the Falcon 9 up and running before they can consider launching the first Falcon Heavy.

Judy Garland – Somewhere over the rainbow
An evening pause: I posted this performance back on November 23, 2010, had forgotten, and found it again by accident. It bears another viewing. As noted at the youtube link,
Judy Garland only performed “Over The Rainbow” twice during her many television appearances, which spanned 14 years. She performed it on her first TV Special, “Ford Star Jubilee” in the episode called “The Judy Garland Special” in 1955, and sang it to her children on The Christmas Edition of her weekly TV show “The Judy Garland Show” (1963).
Here Judy is dressed up [in the first special] as the tramp character she played when doing a duet with Fred Astaire in the film ‘Easter Parade’.
Watch. It shows why she was both a great singer and a great actress.
SpaceX pinpoints likely cause of Falcon 9 failure
The investigation into the failure of the Falcon 9 launch June 28 now thinks the cause was a failed strut in the upper stage.
The struts are 2 feet long and about an inch thick at its thickest. SpaceX does not make the struts, a supplier does. From now on, each one will be individually checked, Musk said, and the design and material may be altered for added strength. The struts are designed to handle 10,000 pounds of force at liftoff; at the time of the accident, they would have been seeing only 2,000 pounds of force. A failure at such a low threshold is “pretty crazy,” Musk said. The strut most likely failed at its attachment point, he added.
Another change: Beginning with its next launch, each Dragon cargo carrier will be equipped with software for deploying its parachutes. The Dragon destroyed last month, along with an estimated $110 million worth of NASA equipment and supplies, would have survived if the parachutes normally used for descent at mission’s end could have been activated, Musk said.
The investigation is still not finalized, but is likely close to completion.

Internet tycoon commits $100 million to alien life search
Russian internet entrepreneur Yuri Milner has given SETI $100 million for a ten year project to accelerate their effort to search for evidence of extraterrestrial life.
Understanding why SETI needs private funding is important:
SETI has been going on since 1960, when radio telescopes became sensitive enough to detect signals from another planet if it was broadcasting signals similar to those which our civilization does. Researchers developed devices that could monitor millions of frequencies at once for any signal that looked at all different from that produced by astronomical objects or the natural background. At first funded by universities and NASA, public funding for SETI was axed by Congress in the early 1990s. Since then, the nonprofit SETI League has received funding of a few million dollars a year from private donors.
Congress correctly cut the funds because it isn’t really the business of the federal government to search for alien life. Some taxpayers really don’t want their money used for that purpose, and they should have the right to say no. Instead, Congress essentially told SETI to do it right: Get private funding from people who want the research done. The work will be done more efficiently for less, and no one will be required to contribute who doesn’t want to.
Milner’s contribution now is the biggest donation yet, and suggests that interest in this research is building culturally.

Baikonur Cosmodrome to open for tourists
The competition heats up: Faced with the possibility that the Russians might eventually end their lease arrangement combined with a desire to make money, Kazakhstan is now planning to make the historic Baikonur spaceport available to tourists.
Why they haven’t done this years ago is baffling. But then, this is Russia and Kazakhstan, not the U.S.

India engine test a success
The competition heats up: India has successfully completed a full duration engine test of its most powerful home-built rocket engine.
The Indian Space Research Organisation (ISRO) successfully conducted the much-awaited ‘full endurance test’ of the Geosynchronous Satellite Launch Vehicle Mk III’s indigenous cryogenic CE-20 engine at ISRO Propulsion Complex (IPRC) in Mahendragiri in the district on Thursday. The CE-20 was ignited and tested for 800 seconds from 5 p.m. to study the performance of the engine though the actual required duration was only 635 seconds.
This success puts them ever closer to creating their own rocket comparable to the Falcon 9 and capable of competing for commercial business in the international launch market.

The government-run Russian space program trims its budget
In the heat of competition: Even as the Russians consolidate their entire aerospace industry into a single entity run by the government, the government has revealed that — due to the country’s recent economic troubles — the budget for space will have to be trimmed.
I found the juxtaposition of these two stories today quite revealing, and illustrates to me the fundamental problem with the Russian Soviet-style government-run approach. Under the competitive, capitalist system that the U.S. is finally beginning to adopt for its space program, when the economy forces budget cuts, competition naturally requires the different companies in the industry to lower costs and innovate. If they don’t, their competitors will get the business. This in turn keeps the industry vibrant, and actually acts to end the tough economic times.
In the Soviet-style system, there is no incentive to compete or innovate. There is only one company, no competition, and everything is decided by a single leadership on top. The government can demand innovation by command from above, but this is not the most effective way to make it happen. Some will obey the commands and try harder. Most however will simply hunker down during hard times, taking fewer risks to cover their asses so they won’t be a target for those budget cuts.
Moreover, with a single government entity running everything, if the economy goes sour the budget must be cut to the entire industry. And since the cuts are determined by a handful of powerful government officials at the top, using money they obtained by coercion (tax-dollars) and not from customers who voluntarily purchased the product, they have no guidance on what parts of the industry to cut. They are just as likely cut the best because it involves too much risk, or because their buddies in a poorly run agency bribed them more.
Capitalism, however, provides competing independent companies, some of which are going to have their own sources of income that might flow independent of a shrinking economy. And it is quality that determines who lives and who dies, not corrupt and powerful government officials. The better companies gain customers, while the less efficient companies naturally fall by the wayside. Thus, during hard economic times competitive capitalism actually works to increase an industry’s efficiency while simultaneously helping to reinvigorate the industry.
This all suggests to me once again that while the consolidation in Russia of its aerospace industry might provide them a short-term burst of success, in the long run they will find it difficult to keep up with America’s private companies.

SpaceX in no hurry to launch 4000 satellite constellation
In the heat of competition: During an interview on July 7, Elon Musk noted that SpaceX’s project to launch a 4,000 satellite communications constellation will be not be hurried.
“A lot of companies have tried it and broken their pick on it,” Musk said in response to an audience question during an appearance at the International Space Station Research and Development Conference here. “We want to be really careful about how we make this thing work, and not overextend ourselves.”… “We’re hopefully going to launch a test satellite next year,” Musk said in Boston, not going into detail about the satellite’s capabilities.
Musk indicated that SpaceX was not in a rush to develop the system. “We’re still in the early stages of a big LEO constellation communications idea,” he said. “I think the long-term potential of it is pretty great, but I don’t want to overplay or overstate things.”

NASA names its astronauts for the first Dragon and CST-100 flights
The competition heats up: NASA today named the four government astronauts that will fly on the first manned demo flights to ISS of SpaceX’s Dragon and Boeing’s CST-100.
Bob Behnken, Eric Boe, Doug Hurley and Sunita Williams are veteran test pilots who have flown on the shuttle and the International Space Station. ….
NASA said the four astronauts will train with both companies and have not yet been assigned to flights. Two-person crews will fly the first test flights by each capsule, after they have completed an orbital test flight without people on board. Company proposals anticipate an all-NASA crew flying SpaceX’s Dragon test flight, with Boeing’s CST-100 carrying a split NASA-Boeing crew. Boeing has not yet identified its astronaut.

Some results from SpaceX’s Dragon launchpad abort test
SpaceX has revealed some of the results from their Dragon launchpad abort test in May, which may explain why they have delayed the launch abort test until next year.
SpaceX engineers are evaluating the results of the May 6 pad abort test, in which the prototype Crew Dragon rocketed away from Cape Canaveral’s Complex 40 launch pad, reached an altitude of nearly one mile, and splashed down under parachutes just offshore in the Atlantic Ocean. Officials said data from the test showed a slight underperformance of the SuperDraco jetpack, and capsule did not reach the top speed and altitude targeted by engineers. But the test was successful by NASA’s standards, and the space agency awarded SpaceX a $30 million milestone payment after data reviews. [emphasis mine]
The article says that the delay is to make sure they are doing a launch abort test with the capsule design they intend to use, rather than an earlier design. I wonder if they also have decided they need more time to tweak their designs after this first test, and thus don’t want to use the capsule they had original planned to use since it has an older design.
Instead, the plan is to use the actual capsule after it has flown to ISS in their unmanned demo test flight of the manned capsule. They will not only be using their in-flight design for the test, this will give them extra time to study the results from the first test and revise the SuperDraco engines.
