ULA pinpoints cause of Atlas 5 premature shutdown

In the heat of competition: ULA has completed its investigation into the premature shutdown of the Atlas 5 first stage during its March launch of Orbital ATK’s Cygnus capsule and has corrected the problem.

An extensive review of all post-flight data observations determined that at approximately T+222 seconds, an unexpected shift in fuel pressure differential across the RD-180 Mixture Ratio Control Valve (MRCV) and a reduction in fuel flow to the combustion chamber caused an oxidizer-rich mixture of propellants and a reduction in first stage performance. The imbalanced propellant consumption rate resulted in depletion of the first stage oxidizer with significant fuel remaining at booster engine shutdown. The engine supplier has implemented a minor change to the MRCV assembly to ensure the anomaly does not occur on future flights.

Engine hot-fire testing, extensive component and assembly level testing and analyses have been performed to confirm the findings. Detailed inspections and minor hardware replacement on all engines will support the current launch manifest.

They have now scheduled the next Atlas 5 launch for June 24.

Orbital ATK delays Antares launch until August

In the heat of competition: The review of Orbital ATK’s May 31st static fire test of its Antares rocket has caused the company to delay the upgraded rocket’s first launch until August.

Additional information pointed to data on “vibrations” during the Static Fire test that could be deemed as a problem for the vehicle’s avionics. A “fix” was already understood to have been approved.

Orbital ATK, while admitting the launch is slipping from its early July launch date estimate to a date likely to be in the August timeframe, pointed to trajectory evaluations as a specific relation to the launch date deliberations. “Final trajectory shaping work is also currently underway, which is likely to result in an updated launch schedule in the August timeframe,” added Orbital ATK.

They expect to make a decision on launch date in a few weeks.

Successful ULA Delta 4 Heavy launch today

The competition heats up: ULA today successfully launched a U.S. National Reconnaissance Office spy satellite, using what is presently the world’s most powerful rocket, the Delta 4 Heavy.

In many ways, this rocket’s launch, which you can see in the video embedded below the fold, gives a rough idea of what a Falcon Heavy launch will look like, since the rockets have somewhat similar configurations.

Elon Musk to meet with Defense Secretary

The competition heats up: A private meeting to discuss modern innovation between Elon Musk and Defense Secretary Ash Carter has been scheduled for Wednesday.

Ash Carter, the U.S. Secretary of Defense, and Elon Musk, SpaceX’s founder and chief executive, will discuss innovation June 8 in a private meeting, the Pentagon’s top spokesman said. “Elon Musk is one of the most innovative minds in this country and the secretary, as you know, has been reaching out to a number of members of the technology community to get their ideas, their feedback, find out what’s going on in the world of innovation,” Peter Cook, the Pentagon’s press secretary said during a June 6 briefing. “The secretary’s had a number of meetings with business leaders and innovation leaders in particular out in Silicon Valley, other parts of the country, and I think that’s his goal here: to hear directly from Elon Musk on some of these issues.”

The meeting is private, which means an agenda or discussion items are generally not released. More details were not immediately available.

I am sure about one thing: This meeting is going to make the corporate board of ULA very nervous.

Congress demands Air Force spend less and more at the same time

A House budget report has cut the Air Force launch budget while simultaneously requiring the Air Force to favor more expensive launch companies.

In addition to cutting the funding available for new launch contracts, House appropriators also want the Air Force to consider “the best value to the government” in evaluating bids.

ULA has been pushing for the best-value approach since it sat out last fall’s GPS-3 launch competition saying it couldn’t win a price shootout against SpaceX, which will launch the satellite which was awarded an $82.7 million contract last month for a May 2018 launch of a GPS-3 satellite. That contract was awarded as part of a best value source selection. “We do not yet feel we are in a position to win price-only competitions with our competitor,” Tory Bruno, ULA president and chief executive, said in a March interview with SpaceNews. “We believe we have better performance, reliability and schedule certainty.” Those traits would carry greater weight in a best-value competition.

Only our precious Congress. On one hand they cut the budget for launches because they think the Air Force is wasting money On the other they demand that the Air Force spend extra millions on launch contracts so that the company they favor, ULA, gets the work. One would almost think they do not have the nation’s interests in mind..

ULA’s CEO explains why they are retiring Delta

Tory Bruno, the CEO of ULA, explained in an op-ed today why his company is discontinuing its use of Boeing’s Delta family of rockets and focusing exclusively on Lockheed Martin’s Atlas 5 and its eventual replacement, the Vulcan Centaur.

Delta is an amazing rocket, but it’s costly to produce. Its burnt-orange foam insulation has to be applied by hand. Its production line is bigger and more complex than Atlas’s. And its components are pricier.

Bruno’s purpose with this op-ed is to convince Congress to leave his company alone while they develop the new Vulcan rocket. Congress keeps proposing outlawing use of the Atlas 5 with its Russian engines, and Bruno does not want that, at least not until the Vulcan is flying. He is also trying to reduce his costs by discontinuing Delta, which in turn would allow him to lower prices for his Atlas 5 and compete more effectively with SpaceX.

Though I understand Congress’s concerns, I do find it sad that in modern America a private businessman has to lobby Congress for the right to run his company as he sees fit.

ULA shuffles Atlas 5 schedule

ULA has rearranged the upcoming launch schedule of its Atlas 5 in the wake of its investigation of the valve issue that causes a premature shutdown of the first stage Russian engine during the Cygnus launch in March.

Originally they had intended to do three launches before the September 8 launch of NASA’s Osiris-REX asteroid mission. Now they will only do two, to give them additional time to test the rocket that will launch Osiris-REX.

August will be spent stacking an Atlas 5 rocket with a single solid booster, the 411 configuration, and rolling the vehicle to the pad for a rare countdown dress rehearsal to ensure systems are operating correctly ahead of the time-sensitive launch of NASA’s OSIRIS-REx probe to asteroid Bennu.

The spacecraft has a launch window that closes October 12.

Congress micro-manages rocket engineering again

In an effort to funnel money to Aerojet Rocketdyne at the cost of every other rocket company in the nation, the House Armed Services Committee has written a bill that tells the Air Force exactly how it will build its future rockets.

“The Committee shares the concern of many members that reliance on Russian-designed rocket engines is no longer acceptable,” the committee said April 25. “The Chairman’s Proposal, as recommended by Chairman Rogers of the Subcommittee on Strategic Forces, denies the Air Force’s request to pursue the development, at taxpayer expense, of new commercial launch systems. It instead focuses on the development of a new American engine to replace the Russian RD-180 by 2019 to protect assured access to space and to end reliance on Russian engines. The Mark also holds the Air Force accountable for its awards of rocket propulsion contracts that violated the FY15 and FY16 NDAAs.”

…“The funds would not be authorized to be obligated or expended to develop or procure a launch vehicle, an upper stage, a strap-on motor, or related infrastructure,” says a draft of the 2017 defense authorization bill.

As presently written, the bill would leave the Air Force only one option: use engines built by Aerojet Rocketdyne.

If anything demonstrates the corruption or foolishness of our elected officials, it is this proposal. Not only are they telling the Air Force how to design rockets, they are limiting the options so much that they are guaranteeing that it will either cost us more than we can afford, or it won’t be doable at all. As I say, either they are corrupt (working to benefit Aerojet Rocketdyne in exchange for money), or they are foolish, (preventing the Air Force from exploring as many inexpensive future options as possible).

Next Atlas 5 launch delayed again

In the heat of competition: ULA has once again suspended future Atlas 5 launches indefinitely while it investigates the launch anomaly during the Cygnus launch several weeks ago.

The problem involves the system that delivers kerosene fuel to the rocket’s Russian-made RD-180 first-stage engine. Bruno said he expects to know within the next few days which components are suspect. Engineers have not found anything in the processing of the rocket for that launch on March 22 that was different from any previously flown, Bruno added. “We have a very good idea (of what the problem is), but we’re not quite done isolating it,” Bruno said. “I think in the next few days we should be able to say which components … we’re actually focused on.”

McCain challenges ULA cost figures for new engine

Senator John McCain (R-Arizona), the head of the Senate Armed Services Committee, has questioned the cost numbers that ULA has given the government for replacing the Russian engines it uses in the first stage of its Atlas 5 rocket.

ULA has been trying to convince Congress to let it use those Russian engines indefinitely. McCain wants their use discontinued, now. The result: a battle of numbers.

The real bottom line has really nothing to do with the Russian engines, however. The real bottom line is the bottom line itself: ULA has to quickly develop a rocket that costs less to launch, or else they will lose all their business to SpaceX. Their use of these Russian engines now in the Atlas 5 is really irrelevant, in the long run.

Aerojet Rocketdyne pitches its AR1 rocket engine to reporters

The competition heats up: At a space conference this week Aerojet Rocketdyne pitched its AR1 rocket engine, still under development, as the ideal replacement for the Russian engine in the Atlas 5.

The U.S. Air Force awarded Aerojet Rocketdyne a contract in February worth up to $534 million over five years to certify and start delivering flight-ready AR1 engines in 2019. Aerojet Rocketdyne says it already has kicked in $70 million, with its total investment expected to exceed $250 million over the life of the contract.

Van Kleeck, vice president of Aerojet Rocketdyne’s advanced space and launch business unit, said the Air Force contract — the largest of several propulsion-related awards the service has made in recent months — is a sign of the Air Force’s confidence in the AR1’s ability to provide an expedient replacement for the RD-180 engine the Defense Department is under pressure from Congress to stop using.

United Launch Alliance, however, has anointed Blue Origin’s methane-fueled BE-4 engine as the front runner to replace the RD-180 by serving as the main engine for the Denver company’s next-generation rocket Vulcan.

“The AR1 engine can fly both on an Atlas and Vulcan and it’s the only engine that can do so,” Van Kleeck said.

Aerojet has been losing business to the newer commercial space companies like Blue Origin, and desperately needs to find a customer for the AR1. In the long run the Air Force contract won’t suffice, as it really is no more than government corporate welfare and cannot sustain them as a company. This press conference was part of that effort.

ULA to launch two Bigelow space station modules

The competition heats up: ULA and Bigelow Aerospace have announced a partnership to launch two of Bigelow’s largest space station modules, each with about as much interior space as both Skylab and Mir.

Both will be ready for launch by 2020. Neither company has made clear if they have any outside investment, though they left open the option of working with NASA and having the modules attached to ISS.

Next Atlas 5 launch delayed indefinitely

In the heat of competition: Because of the continuing investigation into the launch issue during its last launch, ULA has now extended the delay of the next launch of its Atlas 5 from one week to an indefinite delay.

The report at the link is very brief, and it also does not give a source. I was not able to find any other reports of this story after doing a web search as well as a search of ULA’s website, so it remains unconfirmed. Nonetheless, I suspect it is real, suggesting the company has uncovered some unexpected issue with the Atlas 5 that now requires more serious action that is going to take time. Stay tuned.

ULA trims workforce

The competition heats up: In an effort to cut its costs, ULA has announced that it is laying off 375 workers.

The job cuts are not because the company is having financial troubles, but because they need to lower their launch prices to compete with SpaceX.They have always had some fat that could be trimmed but have not done so because, before SpaceX, there was no effort in the launch industry to cut costs. SpaceX, and some good healthy competition in a free market, is now forcing this upon everyone.

Vulcan passes first design review

The competition heats up: ULA’s Vulcan rocket has passed its first design review.

This is good news for ULA, but I wouldn’t get too excited. Announcements like this often have little to do with any real construction, and are often made to give the impression to the public and Congress and other investors that something is happening. Right now, all ULA is doing is pushing paper around. Only when they start cutting metal and testing real equipment will I consider Vulcan for real.

The article does provide an interesting tidbit. Despite protests that ULA hasn’t yet made a decision between Blue Origin or Aerojet Rocketdyne for the first stage engine of Vulcan, it was Blue Origin’s engine that they used for the design review, suggesting that this is the engine they plan on using in the real rocket.

DOD opens ULA investigation

The deputy inspector general of the Defense Department has notified the Air Force that he is beginning an investigation into ULA and the DOD over their relationship and contract.

He also made it clear that the investigation was sparked by last week’s comments by a ULA executive who subsequently resigned.

This is all a game. The Air Force and ULA have been colluding for years to squeeze out any competition. There is no one in Washington who needs an investigation to find this out. The inspector general will issue a report, the Air Force will admit its error and promise to do better, and they will then try to have things continue as they have.

The one difference, however, will be that SpaceX will be there, providing real competition. Thus, what matters isn’t the investigation by the inspector general. What matters is the existence of a competing company willing to put cost pressure on ULA and the Air Force.

Atlas 5 launches Cygnus

The competition heats up: A ULA Atlas 5 rocket tonight successfully placed an Orbital ATK Cygnus freighter into orbit to resupply ISS.

This was the second time an Atlas 5 put Cygnus into orbit. The next Cygnus flight will mark the return of Orbital’s Antares rocket.

This Cygnus capsule contains probably one of the more interesting engineering experiments flown by NASA in years. When it leaves ISS in about two months they will ignite a fire inside it to study the way fires spread and burn in weightlessness.

ULA official resigns

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

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.

ULA’s parent companies express caution about Vulcan

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.
