Proton rolled to launchpad for June 8 launch

11:01 am

After a pause in launches lasting one day short of a full year, Russia has rolled its Proton rocket to the launchpad for a hoped-for June 8 launch of a commercial communications satellite.

The article provides a nice overview of Russia’s struggles during the past year, attempting to track down the reasons why their rockets were having problems (corruption at the rocket engine factory) and their repeated attempts to get this rocket off the ground.

They hope, if all goes well, to complete seven Proton launches through the end of 2017 in order to clean up their backlog while also demonstrating that they have solved their quality control problems.

Russia moves to reduce launch costs with new rocket

8:37 am

The head of Roscosmos said today that they are pushing to accelerate the development of a new rocket, dubbed Phoenix, that will reduce launch costs by 20%, lowering the launch price per launch to $55 million.

I have been reading stories like this, about a new wonderful Russian rocket or spacecraft, for decades. First there was Clipper. Then there was Angara, repeatedly. Recently they have been talking up a new manned capsule and cargo ship. Along the way were a number of other forgotten proposals that would revolutionize space travel. None of these proposals however have ever seen the light of day, though Angara has completed two test flights.

In the past, Russia was not under any competitive pressure. They could undercut the launch price of every other rocket company in the world, without doing anything. Now, they face stiff competition that is only going to get stiffer. They need to produce, or they will be out of the game entirely.

The big question is whether they can, as a nationalized space industry run by a government that is rampant with corruption.

Russia completes first military launch in a year

8:51 am

Russia today successfully launched a military payload on a Soyuz rocket, ending a year long gap in such launches due to the discovery of faulty and corrupt practices at rocket engine manufacturing facilities.

The lull in activity has in part been down to manufacturing defects and quality control issues affecting Russia’s production of rocket engines. A contractor was found to have been using cheaper materials in place of precious metals in alloys used to make parts of the engines. Seventy-one Proton engines and a number of Soyuz engines were recalled for inspection and repair.

Reliability concerns have lingered around Russia’s launch fleet in recent years, with Proton failing ten times since 2007 and Soyuz experiencing seven failures in the last eight years. Two Rokots and a Zenit have also failed in the last decade, while Russia’s flagship Fobos-Grunt mission to Mars never left low Earth orbit after the spacecraft itself malfunctioned.

In 2016, Russia experienced just one launch failure – with a Soyuz-U rocket suffering a third stage failure during December’s attempted launch of the Progress MS-04 vehicle to resupply the International Space Station. Despite this, there were two near-misses: a Soyuz-2-1b underperformed during the launch of a GLONASS navigation satellite last May, and the Proton launch in June suffered a second stage engine failure. In both cases the rockets’ upper stages – Fregat-M and Briz-M respectively – were able to alter their flight plans and inject the satellites into their planned orbits despite the anomalies.

They hope to resume Proton flights next month. Either way, it looks likely that in 2017 Russia will launch the fewest rockets in decades.

How Russia’s next ISS module got contaminated

9:44 am

Russia’s next module for ISS, MLM or Nauka, has been delayed years because of the discovery of sawdust sized metal particles throughout the module’s propulsion system. This article describes how this happened, showing the incredibly incompetence and bad quality control that caused it.

At the time, workers at Khrunichev were cutting pipelines and removing other components of the module’s propulsion system, in order to reconfigure it from its original role as a backup to the Zarya FGB module into the MLM. For example, a set of six tanks, which would be used for refueling of the ISS during the FGB mission, were removed from the exterior of the spacecraft in order to make room for scientific instruments and for the attachment of the European Robotic Arm, ERA.

The official conclusion of the probe said that the contamination had stemmed from the “lack of methodological and technological support for the operations of cutting pipeline connections in the pneumatic and hydraulic system, PGS, which was needed to guarantee the meeting of requirements for ensuring the sterility of the internal cavities in the pipelines and system hardware.” It is essentially bureaucratic speak for letting metallic dust formed during sawing off the lines pour into the interior of the remaining components.

According to one legend circulating at GKNPTs Khrunichev, the workers who were sawing off pipelines from the module thought they were dismantling the entire spacecraft for scrap. That story would sound completely unbelievable if not for other almost as incredible incidents of carelessness, poor quality control and incompetence within the industry in recent years, such as the installing navigation sensors on a Proton rocket in the upside down position or loading a Block DM-03 space tug on another Proton with too much propellant.

Read the whole story. It is most revealing of the overall systematic problems within Russia’s aerospace industry.

Soyuz returns ISS crew to Earth

8:12 am

A Russian Soyuz capsule safely returned three astronauts to Earth this morning.

This completes the second flight of the Soyuz-MS upgraded capsule.

The new MS series sports more efficient solar panels, a new Kurs NA approach and docking system weighing less than half that of its predecessor, additional micro-meteoroid debris shielding, and a modified docking and attitude control engine – which will add redundancy during docking and deorbit burns.

R.I.P: Georgy Grechko

8:39 am

Russian cosmonaut Georgy Grechko died today at the age of 85.

Grechko was one of the Soviet Union’s most important early cosmonauts, flying some of the first long term missions on several of Russia’s early Salyut stations. He was also important in that in the first real elections run by the Soviet Union he ran for office against party officials, won, and helped throw the Communists out of power.

I met and interviewed Grechko when I was writing Leaving Earth. He struck me as a kind and intelligent person, exactly the kind of person you’d want in charge, and who rarely gets that chance. Russia is diminished by his passing.

Russia proposes extending ISS beyond 2024

7:13 am

The head of Roscosmos said at a space conference this week that his nation is open to extending its ISS partnership with the U.S. beyond 2024 to 2028.

Russia has several good and bad reasons for wanted to do this.

  • Their shortage of cash will make it difficult for them to fly their own station.
  • They need a space station in order to maintain the jobs that exist at their mission control as well as throughout their space industry.
  • There are many good political reasons for them to maintain this space partnership with the U.S. It prevents the U.S. from completely breaking off relations, should Russia do something the U.S. doesn’t like (such as invading a nearby country).
  • They recognize that the ability to do long term research in an orbiting space station is essential for anyone who plans future interplanetary missions.

I will let my readers decide which of these reasons are the good reasons, and which are bad.

Russia responds to SpaceX reused booster success

10:57 pm

A bunch of stories from Russia today appear to express that country’s political response to SpaceX’s success yesterday in launching a commercial satellite using a previously flown first stage.

It appears that these stories are quoting a variety of Russian officials who apparently did not get their stories straight. Also, it appears that much of what they are saying here is pure bluster. For example, in the third link the official makes the silly claim that the ability of their rocket engines to be started and then restarted repeatedly proves they are dedicated to re-usability. And the first two links don’t provide much back-up for the claims that they can complete with SpaceX, especially since SpaceX presently charges a third less than they do per launch, and that is using new boosters. With reused boosters SpaceX’s launch fees will be less than half what Russia has been charging for a Proton launch ($90 million vs $40 million).

Similarly, the claim that they will complete 30 launches this years is absurd. They won’t be able to launch Proton until May, at the soonest, because of the need to remove defective parts from all of their in-stock engines. Soyuz launches are similarly delayed while they check its engines also. To complete 30 launches in only seven months seems very unrealistic to me, especially since the best they have done in a full year this century is 34 launches, with an average slightly less than 30 per year.

Nonetheless, this spate of stories and statements by Russian officials shows that they are feeling the heat of competition, and also feel a need to respond. The first story has this significant statement:

Russia’s State Space Corporation Roscosmos is responding to the challenges with available possibilities, he added. “It has announced a considerable reduction in the cost of Proton rocket launches. The commercial price of this rocket’s launch is considerably higher than its prime cost and we have the potential for the price cut. But customers are giving up our services because the number of payloads [satellites] remains unchanged and does not grow. Correspondingly, a new player on the market snatches away a part of orders,” the expert noted.

Because of Russia’s low labor costs they have always had a large profit margin on their Proton launches. The $90 million they charged was set just below what Arianespace charged for its launches. It appears they are now planning to lower their prices further to match SpaceX.

Bad solder joints cause of Russian Proton engine defects

8:49 am

The problem that has forced the Russians to recall all Proton second and third stage engines has been identified as the use of the wrong materials in solder joints.

According to specifications, the structural walls and the nozzle chamber of the gas generator had to be fused together with the help of the solder designated G70NKh, which employs nickel, chromium and manganese alloy (Ni-Cr-Mn). However the investigation revealed that due to mismanagement of the raw material usage at the Voronezh Mechanical Plant, the required alloy had been replaced with the PZhK-1000 solder comprised of palladium, nickel, chromium and silicon (Pd-Ni-Cr-Si). Because the replaced solder did not meet specifications, it could lead to structural disintegration of the nozzle head during the firing of the gas generator.

The discovery of the problem with the solder triggered inspection of other engines and revealed that all RD-0210 and RD-0212 engines from the second and third stages that had been manufactured during 2015 and 2016 had been equipped with defective gas generators. In order to re-certify these engines for flight, each of them would have to be disassembled, the gas generator would have to be removed and replaced, followed by the re-assembly and re-testing of each engine!

The article also notes that the next Angara rocket is also “unfit for flight” due to unspecified defects. It also notes widespread corruption and mismanagement throughout the Russian aerospace industry.

Sadly, the decision by the Putin administration to consolidate their industry into one huge corporation run by the government, and thus eliminate any competition, is only going to make solving this problem more difficult. What Russia needs is competition, with many different companies free to challenge each other for business. It also needs to allow companies to fail and go out of business.

Instead, everything is controlled from above, and thus no competition can happen. Rather than finding a new company to build these engines, the government is going to provide the company “economic aid” in order to modernize it. This is like putting a band-aid on a broken bone.

Practically every Russian Proton rocket engine defective

4:36 pm

The investigation of the Russian supply of rocket engines for its Proton rocket has discovered that practically every engine, numbering over seventy, had defects that needed repair.

71 engines, mostly used to power the second and third stages of the Proton rocket, require complete overhauls to remove defects. Arbuzov did not specify what was wrong with the engines. In January, Interfax reported on an investigation into high-quality metals swapped by a plant manager for cheaper alternatives. “Most of the work will be done in 2017, but we understand that some portion will inevitably slip into 2018,” Arbuzov said. “Our main goal is to avoid disrupting the government space program’s launch schedule, or the schedules of the Defense Ministry and commercial customers.”

There is also the possibility that these defects will be found in Soyuz rocket engines as well. Stay tuned.

Next Proton launch tentatively set for May

9:05 am

The Russians have tentatively scheduled their next Proton launch for May, contingent on the repair work being done on the rocket’s engines.

The engine repairs are required because of corruption in the factory that made them. Previously, the Russians had hoped to get Proton off the ground by April. That is no longer likely.

The link above includes a manifest of Russian launches through next year. Interestingly, it only includes three commercial launches. A quick review of the launches listed at this site only includes another three or so commercial launches much farther in the future. All in all, it appears that the Russians are getting less business for this rocket. I also suspect this will remain the case until they get things fixed and begin launching again, though they will need to cut their prices significantly to match SpaceX’s.

More problems for Russian ISS module

10:37 pm

A Russian module intended for ISS, delayed for years because of technical problems, appears to have more issues that could delay it further, and might even prevent its launch entirely.

As its original 2007 launch date came and went, more and more delays pushed back the MLM’s launch. Then, in 2013, engineers discovered a leaking fueling valve as well as contamination in the propulsion system. At the time, reports said repairs and cleanup would take nearly 10 months.

Those months stretched into years. During the last four years, engineers have been working diligently replacing a jungle of pipelines, valves, and thrusters—part of Nauka’s sophisticated propulsion system—in an effort to get rid of the sawdust contamination introduced during botched upgrades. Because the spacecraft has stayed earthbound much longer than intended, parts of Nauka have also slipped out of warranty.

Fighting off political and logistical concerns surrounding the project—as well suggestions that they ground the MLM entirely until it can serve as the first module of Russia’s own space station—the tedious cleanup and repair effort entered its final phase this year, and the module finally appeared on track for launch at the end of this year or, at the very latest, the first half of 2018.

Then things went from bad to worse. In the past few weeks, engineers found the same contamination they’ve been fighting for years inside the module’s propellant tanks. The repair team tried to wash off these contaminants, but so far all efforts to cleanse the vessels have failed.

Read the whole article. The situation is not good.

Russia puts four engineers on trial for Proton launch failure

8:54 am

Russia has begun the criminal trial of four engineers for their part in the launch failure of a Proton rocket six years ago, in December 2010.

According to the office of Russia’s federal Prosecutor General, employees at RKK Energia used a wrong formula during the fueling of the company’s Block DM-03 upper stage, which received 1,582 kilograms of extra liquid oxygen above the maximum allowable limit. The prosecutors allege that the department head at RKK Energia Stanislav Balakin, the unit head Aleksandr Martynov and his deputy Sergei Lomtev, while being responsible for the development of operational documentation for Block DM-03, failed to ensure that their subordinate engineer Yuri Bolshigin had completed the on-time adjustment of the computation formula controlling the operation of the fueling system.

This is not the right way to encourage good work in Russian aerospace factories. Sure, these guys screwed up, but you don’t put them on trial, you fire them and hire better people. Making them scapegoats in this way is only going to scare away the best people, who won’t want to join a high-risk industry where, if they make a mistake, they might find themselves in prison.

NASA buys Soyuz seats from Boeing

9:26 am

NASA has purchased two additional seats from Boeing on a Russian Soyuz capsule and rocket to get astronauts to ISS beyond 2019.

The reason Boeing was able to sell Russian Soyuz seats is because they have obtained them from the Russians in a deal to settle Boeing’s $320 million lawsuit over ending the Russian/Boeing Sea Launch partnership.

Sea Launch deal finalized?

1:29 pm

The competition heats up? Two articles today in the Russia press suggest that either their settlement deal with Boeing over bankrupt Sea Launch is either on the verge of signing or the Russians are trying to pressure Boeing to an agreement by use of the press.

The first article says that a final agreement is about to be signed, but provides no date or indication from Boeing that they have agreed to terms. The second announces that the private Russian company that is acquiring Sea Launch from the Russian government to compete in the commercial launch market has been given a launch license by the Russian government, and will launch its first rocket from Baikonur later this year, using the Ukrainian Zenit-M rocket that was designed to fly from the Sea Launch floating platform. .This launch is intended as a test flight prior to restarting launches from the Sea Launch platform itself.

The complexity of this Sea Launch situation boggles my mind. Russia has sold Sea Launch to a private Russian airline company, S7, which will use a Ukrainian rocket to launch satellites from the Sea Launch platform. Before that can happen however Russia has to settle its dispute with Boeing, which won a $300+ million settlement in court over the breakup of their Sea Launch partnership. That settlement reportedly includes free passenger seats on Soyuz flights to ISS, which Boeing is reportedly offering to sell to NASA, which might need them. Meanwhile, Russia does not seem to have a problem with a Russian company using a Ukrainian rocket, even though Russia itself has completely banned the use of Ukrainian equipment on any of its own space rockets or capsules.

The business of commercial space sometimes amazes me.

Last Soyuz-U launches Progress to ISS

10:25 am

Russia today successfully launched a Progress freighter to ISS using its last Soyuz-U rocket.

The Soyuz-U has been launched hundreds of times since the 1970s, but has been replaced by Russia because it uses equipment made in Ukraine. The newer versions of the Soyuz rockets are completely home-built, but also have been plagued by quality control problems and corruption within Russia.

Russia proposes increased space cooperation with the U.S.

9:48 pm

They need the money: At a science conference on Tuesday the Russian ambassador to the United States stated that his country would welcome increased space cooperation between the two countries.

“I think it would be premature for me to speculate as to whether this zone of overlapping interests will increase or decrease,” Kislyak said. “We haven’t heard a new policy yet from the United States.” He suggested, though, there may be opportunities for the countries to cooperate on NASA’s long-term plans for human Mars exploration. “That is moon exploration, which is very much on our agenda. It’s space medicine and many, many other issues,” he said. “Our programs are not identical, but there’s always been a lot of overlap that provides room for serious and significant cooperation.”

“If the U.S. government chooses programs that would be extending that kind of cooperation,” he added, “they will find us to be willing to work with you.”

As I said, they need the cash. They want to keep their space industry alive, but low oil prices combined with the corruption that has shut down their launch industry has left them very cash poor. A combined Russian/SLS/Orion project to the Moon would be very helpful for them.
